Only the first two, Roaring data and Column-Key -data are relevant here. Broadly, the Roaring bitmap data -forms the central features -- the bits -- of a large, sparse bitmap matrix. -The Column-Keys are the labels for the columns at the top margin of this matrix. - -For speed, the Roaring bitmap data is stored separately from the -Key data. The Roaring data is stored in sharded files -within a directory heirarchy under PILOSA-DATA-DIR/index_name/field_name/... -The Key translation data is stored in sharded BoltDB databases within -the PILOSA-DATA-DIR/index_name/_key directory. - -The current approach to Roaring file replication involves an -eventually consistent mechanism that uses an Anti-Entropy agent to -fix partial or incomplete replication from the primary shard to all -replica shards. - -Unfortunately, the Anti-Entropy agent approach has proved inadequate on two -fronts. First, it does not provide for immediately consistent reads in the -event that the primary is lost. Second, the Anti-Entropy agent itself experienced -out-of-memory issues that have yet to be resolved. - -Therefore, work is now underway to replace this replication -approach with a more consistent design. - -However, in the meantime, for our customers in production with Molecula -Pilosa, we wish to provide a means to re-establish correct replication. -Thus even in the event of a node failure followed by a read from a replica, the -returned read will be correct. - -The pilosa-fsck tool can therefore be seen as a temporary, stop-gap -measure to address immediate issues while the cluster replication -mechanism is replaced. - -The second factor motivating the creation of pilosa-fsck was the discovery -of a bug in the Key-translation process. Unfortunately this was a hard -to reproduce bug. It happened only on the customer's premises, -and only after running the system for a long time, with a -large amount of data, and with various eccentric node failures -and recoveries. - -However, we were able to reproduce a plausible explanation. -Non-primary replicas were creating keys when they should have been -forwarding the request to the primary. Correcting this bug is impetus -for the v2.1.4 release of Molecula Pilosa. - -A fine point here: since we were not able to precisely reproduce the customer's -issue in the development environment, we cannot guarantee with 100% -certainty that we have actually addressed the bug that the customer -was seeing. - -Therefore we also desired an additional insurance -policy. We wished to be able to empower customers to proactively discover any -future Key-translation issues that happen in their on-premise systems. - -To do this, we proposed providing select customers with the pilosa-fsck -tool which can analyze their offline backups for issues. - -Optionally, these issues can also be repaired in-place in the -offline backup on which pilosa-fsck is run. - -The -fix flag repairs both kinds of replication issues. - -Solution Approach: mechanism of action --------------------------------------- - -The pilosa-fsck is run offline on a full set of backups taken from -all nodes in a Pilosa cluster. It runs on a single computer that -must be separate from the production or staging Pilosa environments. - -When run, pilosa-fsck analyzes the differences between the -primary and its replicas. Both the Roaring -files and the Key translation databases are analyzed. -The computer running pilosa-fsck must have the same or more -memory as the Pilosa nodes in the cluster, as it will -"pretend" to be each Pilosa node in turn. However, as each -node's backup is closed before the next node's backup is -opened, we do not require substantially more memory than a single -production node. Short Blake3 cryptographic checksums are -computed for each Roaring fragment and each Key translation -database. These are held in memory (and printed to the log) -for comparing nodes. This comparison forms the heart of -the consistency checks, and is the basis for any subsequent -repair. - -We recommend capturing both stdout and stderr to a log. -Use `&> log` or `2>&1 > log` at the end of the -pilosa-fsck invocation to save a log of the run to disk. - -In a typical cluster, the Replication factor R may be less -than the number of nodes N in the cluster. For example, while -N may be 4, the R may be only 3.

Pilosa can run on very small machines and works well with even a medium sized dataset on a personal laptop. If you are reading this section, you are likely ready to deploy a cluster of Pilosa servers handling very large datasets or high velocity data. These are guidelines for running a cluster; specific needs may differ. - -#### Memory - -Pilosa holds all row/column bitmap data in main memory. While this data is compressed more than a typical database, available memory is a primary concern. In a production environment, we recommend choosing hardware with a large amount of memory >= 64GB. Prefer a small number of hosts with lots of memory per host over a larger number with less memory each. Larger clusters tend to be less efficient overall due to increased inter-node communication. - -#### CPUs - -Pilosa is a concurrent application written in Go and can take full advantage of multicore machines. The main unit of parallelism is the [shard](../data-model/#shard), so a single query will only use a number of cores up to the number of shards stored on that host. Multiple queries can still take advantage of multiple cores as well, so tuning in this area is dependent upon the expected workload. - -#### Disk - -Even though the main dataset is in memory Pilosa backs up to disk frequently. We recommend SSDs—especially if you have a write-heavy application. - -#### Network - -Pilosa is designed to be a distributed application, with data replication replicated across the cluster. As such, every write and read needs to communicate with several nodes. Therefore fast internode communication is essential. If using a service like AWS we recommend that all nodes exist in the same region and availability zone. The inherent latency of spreading a Pilosa cluster across physical regions is not usually worth the redundancy protection. Since Pilosa is designed to be an indexing service there should already be a system of record, or ability to rebuild a cluster quickly from backups. - -#### Overview - -While Pilosa does have some high system requirements it is not a best practice to set up a cluster with the fewest, largest machines available. You want an evenly distributed load across several nodes in a cluster to easily recover from a single node failure, and have the resource capacity to handle a missing node until it's repaired or replaced. Nor is it advisable to have many small machines, as the internode network traffic will become a bottleneck. You can always add nodes later, but that does require some down time. - -### Open File Limits - -Pilosa requires a large number of open files to support its memory-mapped file storage system. Most operating systems put limits on the maximum number of files that may be opened concurrently by a process. On Linux systems, this limit is controlled by a utility called [ulimit](https://ss64.com/bash/ulimit.html). Pilosa will automatically attempt to raise the limit to `262144` during startup, but it may fail due to access limitations. If you see errors related to open file limits when starting Pilosa, it is recommended that you run `sudo ulimit -n 262144` before starting Pilosa. - -On Mac OS X, `ulimit` does not behave predictably. The Mac OS X system has a utility called csrutil that prevents you from changing the open file limit easily. One workaround that may work for you involves disabling the csrutil program. To disable the csrutil program, restart your laptop and when the start up screen pops up, hold down command + R to enter Recovery Mode. Open a terminal and enter `csrutil disable`, then restart your computer as you normally would. Now that the csrutil is disabled, you can change the open file limit. The open file limit can be changed by creating the following files and changing their ownership: - -Copy the contents of [this](https://github.com/wilsonmar/mac-setup/blob/master/configs/limit.maxfiles.plist) file into a new file on your system located at /Library/LaunchDaemons/limit.maxfiles.plist, then run: - -``` -sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist -``` - -Copy the contents of [this](https://github.com/wilsonmar/mac-setup/blob/master/configs/limit.maxproc.plist) file into a new file on your system located at /Library/LaunchDaemons/limit.maxproc.plist, then run: - -``` -sudo chown root:wheel /Library/LaunchDaemons/limit.maxproc.plist -``` - -To ensure the open file limit has successfully changed, run `ulimit -a`. Your open files should be set to a number greater than 256 (in the range of 524288) and your max users processes should be greater than 709 (in the range of 2048). - -### Importing and Exporting Data - -#### Importing - -The import API expects a csv of the format `Row,Column`. - -When importing large datasets remember it is much faster to pre sort the data by row ID and then by column ID in ascending order. You can use the `--sort` flag to do that. Also, avoid querying Pilosa until the import is complete, otherwise you will experience inconsistent results. - -``` -pilosa import --sort -i project -f stargazer project-stargazer.csv -``` - -We recommend importing data using official Pilosa client libraries. You can find the corresponding documentation at: -* [Go client imports documentation](https://github.com/pilosa/go-pilosa/blob/master/docs/imports-exports.md) -* [Java client imports documentation](https://github.com/pilosa/java-pilosa/blob/master/docs/imports.md) -* [Python client imports documentation](https://github.com/pilosa/python-pilosa/blob/master/docs/imports.md) - -##### Importing Integer Values - -If you are using [integer](../data-model/#bsi-range-encoding) field values, the CSV file should be in the format `Column,Value`. - -``` -pilosa import -i project -f stargazer-counts project-stargazer-counts.csv -``` - -##### Importing Boolean Values - -If you are using a [boolean](../data-model/#boolean) field, the CSV file should be in the format `Boolean,Value`, where `Boolean` is either `0` (false) or `1` (true). - -For example, importing a file with the following contents will result in columns 3 and 9 being set in the `false` row, and columns 1, 2, 4, and 8 being set in the `true` row. -``` -0,3 -0,9 -1,1 -1,2 -1,4 -1,8 -``` - -
-

Note that you must first create a field. View Create Field for more details. The `-e` flag can create the necessary schema when using a field of type "set".

-
- -#### Clearing Data via Import - -By using the `--clear` flag with the import command, Pilosa will clear the values provided in the import payload. - -For example, importing a file with the following contents along with the `--clear` flag will result in data being cleared from row 0, column 9; row 1, columns 2 and 8; and row 3, column 12. Clearing a value that doesn't exists is allowed. -``` -0,9 -1,2 -1,8 -3,12 -``` - -#### Exporting - -Exporting data to csv can be performed on a live instance of Pilosa. You need to specify the index and the field. The API also expects the shard number, but the `pilosa export` sub command will export all shards within a field. The data will be in csv format `Row,Column` and sorted by column. -```request -curl "http://localhost:10101/export?index=repository&field=stargazer&shard=0" \ - --header "Accept: text/csv" -``` -```response -2,10 -2,30 -3,426 -4,2 -... -``` - -### Versioning - -Pilosa follows [Semantic Versioning](http://semver.org/). - -MAJOR.MINOR.PATCH: - -* MAJOR version when you make incompatible API changes, -* MINOR version when you add functionality in a backwards-compatible manner, and -* PATCH version when you make backwards-compatible bug fixes. - -#### PQL versioning - -The Pilosa server should support PQL versioning using HTTP headers. On each request, the client should send a Content-Type header and an Accept header. The server should respond with a Content-Type header that matches the client Accept header. The server should also optionally respond with a Warning header if a PQL version is in a deprecation period, or an HTTP 400 error if a PQL version is no longer supported. - -#### Upgrading - -To upgrade Pilosa: - -1. First, upgrade the [client libraries](../client-libraries/) you are using in your application. Generally, a client version `X` will be compatible with the Pilosa server version `X` and earlier. For example, `python-pilosa 0.9.0` is compatible with both `pilosa 0.8.0` and `pilosa 0.9.0`. -2. Next, download the latest release from our [installation page](/docs/latest/installation/) or from the [release page on Github](https://github.com/pilosa/pilosa/releases). -3. Shut down the Pilosa cluster. -4. Make a backup of the [data directory](../configuration/#data-dir) on each cluster node. -5. Upgrade the Pilosa server binaries and any configuration changes. See the following sections on any version-specific changes you must make. -6. Start Pilosa. It is recommended to start the cluster coordinator node first, followed by any other nodes. - -##### Version 1.4 - -Pilosa 1.4.0 changes the way that integer fields are stored. The upgrade from old format to new is handled automatically, however you will not be able to downgrade to 1.3 should you wish to do so. We *always* recommend taking a backup of your Pilosa data directory before upgrading Pilosa, but doubly so with this release. - -### Resizing the Cluster - -If you need to increase (or decrease) the capacity of a Pilosa server, you can add or remove nodes to a running cluster at any time. Note that you can only add or remove one node at a time; if you attempt to add multiple nodes at once, those requests will be enqueued and processed serially. Also note that during any resize process, the cluster goes into state `RESIZING` during which all read/write requests are denied. When the cluster returns to state `NORMAL` then read/write operations can resume. The amount of time that the cluster stays in state `RESIZING` depends on the amount of data that needs to be moved during the resize process. - -#### Adding a Node - -You can add a new, empty node to an existing cluster by starting `pilosa server` on the new node with the correct configuration options. Specifically, you must specify the [cluster coordinator](../configuration/#cluster-coordinator) to be the same as the coordinator on the existing nodes. You must also specify at least one valid [gossip seed](../configuration/#gossip-seeds) (preferably multiple for redundancy). When the new node starts, the coordinator node will receive a `nodeJoin` event indicating that a new node is joining the cluster. At this point, the coordinator will put the cluster into state `RESIZING` and kick off a resize job that instructs all of the nodes in the cluster how to rebalance data to accomodate the additional capacity of the new node. Once the resize job is complete, the coordinator will put the cluster back to state `NORMAL` and ensure that the new node is included in future queries. - -If the node is being added to a cluster which contains no data (for example, during startup of a new cluster), the coordinator will bypass the `RESIZING` state and allow the node to join the cluster immediately. - -#### Removing a Node - -In order to remove a node from a cluster, your cluster must be configured to have a [cluster replicas](../configuration/#cluster-replicas) value of at least 2; if you're removing a node that no longer exists (for example a node that has died), there must be at least one additional replica of the data owned by the dead node in order for the cluster to correctly rebalance itself. - -To remove node `localhost:10102` from a cluster having coordinator `localhost:10101`, first determine the ID of the node to be removed. If the node to be removed is still available, you can find the ID by issuing a `/status` request to the node. The node's ID is in the `localID` field: -``` request -curl localhost:10101/status -``` -``` response -{ - "state":"NORMAL", - "nodes":[ - {"id":"24824777-62ec-4151-9fbd-67e4676e317d","uri":{"scheme":"http","host":"localhost","port":10101}} - {"id":"40a891fa-243b-4d71-ae24-4f5c78a0f4b1","uri":{"scheme":"http","host":"localhost","port":10102}} - {"id":"9fab09cc-3c26-4202-9622-d167c84684d9","uri":{"scheme":"http","host":"localhost","port":10103}} - ], - "localID": "40a891fa-243b-4d71-ae24-4f5c78a0f4b1" -} -``` - -If the node to be removed is no longer available, you can get the IDs of the nodes in the cluster by issuing a `/status` request to any available node: -``` request -curl localhost:10101/status -``` -``` response -{ - "state":"NORMAL", - "nodes":[ - {"id":"24824777-62ec-4151-9fbd-67e4676e317d","uri":{"scheme":"http","host":"localhost","port":10101}} - {"id":"40a891fa-243b-4d71-ae24-4f5c78a0f4b1","uri":{"scheme":"http","host":"localhost","port":10102}} - {"id":"9fab09cc-3c26-4202-9622-d167c84684d9","uri":{"scheme":"http","host":"localhost","port":10103}} - ], - "localID": "40a891fa-243b-4d71-ae24-4f5c78a0f4b1" -} -``` - -Once you have the ID of the node that you want to remove from the cluster, issue the following request: -``` -curl localhost:10101/cluster/resize/remove-node \ - -X POST \ - -d '{"id": "40a891fa-243b-4d71-ae24-4f5c78a0f4b1"}' -``` -At this point, the coordinator will put the cluster into state `RESIZING` and kick off a resize job that instructs all of the nodes in the cluster how to rebalance data to accomodate the reduced capacity of the cluster. Once the resize job is complete, the coordinator will put the cluster back to state `NORMAL` and ensure that the removed node is no longer included in future queries. - -Note that you can't directly remove the coordinator node. If you need to remove the coordinator node from the cluster, you must first [make one of the other nodes the coordinator](#changing-the-coordinator). - -#### Aborting a Resize Job - -If at any point you need to abort an active resize job, you can issue a `POST` request to the `/cluster/resize/abort` endpoint on the coordinator node. -For example, if your coordinator node is `localhost:10101`, then you can run: -``` -curl localhost:10101/cluster/resize/abort -X POST -``` -This will immediately abort the resize job and return the cluster to state `NORMAL`. Because data is never removed from a node during a resize job (only once a resize job has successfully completed), aborting a resize job will return the cluster back to the state it was in before the resize began. - -#### Changing the Coordinator - -In order to assign a different node to be the coordinator, you can issue a `/cluster/resize/set-coordinator` request to any node in the cluster. The payload should indicate the ID of the node to be made coordinator. -``` -curl localhost:10101/cluster/resize/set-coordinator \ - -X POST \ - -d '{"id": "9fab09cc-3c26-4202-9622-d167c84684d9"}' -``` - -### Backup/restore - -Pilosa continuously writes out the in-memory bitmap data to disk. This data is organized by Index->Field->Views->Fragment->numbered shard files. These data files can be routinely backed up to restore nodes in a cluster. - -Depending on the size of your data you have two options. For a small dataset you can rely on the periodic anti-entropy sync process to replicate existing data back to this node. - -For larger datasets and to make this process faster you could copy the relevant data files from the other nodes to the new one before startup. - -Note: This will only work when the replication factor is >= 2 - -#### Using Index Sync - -- Shutdown the cluster. -- Modify config file to replace existing node address with new node. -- Restart all nodes in the cluster. -- Wait for auto Index sync to replicate data from existing nodes to new node. - -#### Copying data files manually - -- To accomplish this you will first need: - - List of all indexes on your cluster - - List of all fields in your indexes - - Max shard per index, listed in the `/internal/shards/max` endpoint -- With this information you can query the `/internal/fragment/nodes` endpoint and iterate over each shard -- Using the list of shards owned by this node you will then need to manually: - - setup a directory structure similar to the other nodes with a path for each Index/Field - - copy each owned shard for an existing node to this new node -- Modify the cluster config file to replace the previous node address with the new node address. -- Restart the cluster -- Wait for the first sync (10 minutes) to validate Index connections - -### Diagnostics - -Each Pilosa cluster is configured by default to share anonymous usage details with Pilosa Corp.

Pilosa categorizes rows into different *fields* and quickly retrieves the top rows in a field sorted by the number of columns set in each row. - -Please note that Pilosa is most performant when row and column IDs are sequential starting from 0.

You cannot perform cross-index queries. - -### Column - -Column ids are sequential, increasing integers and they are common to all Fields within an Index.

A Pilosa field might correspond to a single field in a relational table, where each row in a standard Pilosa field represents a single possible value of the relational field. Similarly, an integer field could represent all possible integer values of a relational field. - -#### Relational Analogy - -The Pilosa index is a flexible structure; it can represent any sort of high-cardinality binary matrix. We have explored a number of modeling patterns in Pilosa use cases; one accessible example is a direct analogy to the relational model, summarized here. - -Entities: - - Relational | Pilosa --------------|---------------------------------------------- - Database | N/A *(internal: Holder)* - Table | Index - Row | Column - Column | Field - Value | Row - Value (int) | Field.Value (see [BSI](#bsi-range-encoding)) - -Simple queries: - - Relational | Pilosa ------------------------------------------------|------------------------------------ - `select ID from People where Name = 'Bob'` | `Row(Name="Bob")` - `select ID from People where Age > 30` | `Row(Age > 30)` - `select ID from People where Member = true` | `Row(Member=0)` - -Note that `Row(Member=0)` selects all entities with a bit set in row 0 of the Member field. We could just as well use row 1 to store this, in which case we would use `Row(Member=1)`, which looks a bit more intuitive. In the relational model, joins are often necessary. Because Pilosa supports extremely high cardinality in both rows and columns, many types of joins are accomplished with basic Pilosa queries across multiple fields. For example, this SQL join: - -```sql -select AVG(p.Age) from People p -inner join PersonCar pc on pc.PersonID=p.ID -inner join Cars c on pc.CarID=c.ID -where c.Make = 'Ford' -``` - -can be accomplished with a Pilosa query like this (note that [Sum](../query-language/#sum) returns a json object containing both the sum and count, from which the average is easily computed): - -```pql -Sum(Row(Car-Make="Ford"), field=Age) -``` - -This is one major component of Pilosa's ability to combine relationships from multiple data stores. - -#### Ranked - -Ranked Fields maintain a sorted cache of column counts by Row ID (yielding the top rows by columns with a bit set in each). This cache facilitates the TopN query. The cache size defaults to 50,000 and can be set at Field creation. - -![ranked field diagram](/img/docs/field-ranked.png) -*Ranked field diagram* - -#### LRU - -The LRU cache maintains the most recently accessed Rows. - -![lru field diagram](/img/docs/field-lru.png) -*LRU field diagram* - -### Time Quantum - -Setting a time quantum on a field creates extra views which allow ranged Row queries down to the time interval specified. For example, if the time quantum is set to `YMD`, ranged Row queries down to the granularity of a day are supported. - -### Attribute - -Attributes are arbitrary key/value pairs that can be associated with either rows or columns. This metadata is stored in a separate BoltDB data structure. - -Column-level attributes are common across an index. That is, each column attribute applies to all bits in the corresponding column, across all fields in an index. Row attributes apply to all bits in the corresponding row. - -### Shard - -Indexes are segmented into groups of columns called shards (previously known as slices). Each shard contains a fixed number of columns, which is the ShardWidth. ShardWidth is a constant that can only be modified at compile time, and before ingesting data. The default value is 220. - -Query operations run in parallel, and they are evenly distributed across a cluster via a consistent hash algorithm. - -### Field Type - -Upon creation, fields are configured to be of a certain type. Pilosa supports the following field types: `set`, `int`, `bool`, `time`, and `mutex`. - -#### Set - -Set is the default field type in Pilosa. Set fields represent a standard, binary matrix of rows and columns where each row key represents a possible field value. The following example creates a `set` field called "info" with a ranked cache containing up to 100,000 records. -Row and/or column key can be a string literal (e.g. "value"). This mapping is also stored in a separate BoltDB data structure. Becauase BoltDB does not allow to have empty strings as keys, in pilosa we translate an empty string key into sentinel byte slice: -```go -[]byte{ - 0x00, 0x00, 0x00, - 0x4d, 0x54, 0x4d, 0x54, // MTMT - 0x00, - 0xc2, 0xa0, // NO-BREAK SPACE - 0x00, -} -``` -(where the first three bytes are _zero_ bytes, next four bytes stands for `MTMT` literal and the rest four bytes represent NBSP prefixed and suffixed with _zero_ byte). -In reverse translation, if we get from BoltDB the sentinel key, pilosa will rewrite it into an empty string (`""`). - -``` request -curl localhost:10101/index/repository/field/info \ - -X POST \ - -d '{"options": {"type": "set", "cacheType": "ranked", "cacheSize":100000}}' -``` -``` response -{"success":true} -``` - -#### Int -Fields of type `int` are used to store integer values. Integer fields share the same columns as the other fields in the index, but values for the field must be integers that fall between the `min` and `max` values specified when creating the field. The following example creates an `int` field called "quantity" capable of storing values from -1000 to 2000: - -``` request -curl localhost:10101/index/repository/field/quantity \ - -X POST \ - -d '{"options": {"type": "int", "min": -1000, "max":2000}}' -``` -``` response -{"success":true} -``` - -##### BSI Range-Encoding - -Bit-Sliced Indexing (BSI) is the storage method Pilosa uses to represent multi-bit integers in a bitmap index. Integers are stored as n-bit, range-encoded bit-sliced indexes of base-2, along with an additional row indicating "not null". This means that a 16-bit integer will require 17 rows: one for each 0-bit of the 16 bit-slice components (the 1-bit does not need to be stored because with range-encoding the highest bit position is always 1) and one for the non-null row. Pilosa can evaluate `Row`, `Min`, `Max`, and `Sum` queries on these BSI integers. The result of a `Sum` query includes a count, which can be used to compute an average with no other overhead. - -Internally Pilosa stores each BSI `field` as a `view`. The rows of the `view` contain the base-2 representations of the integer values. Pilosa manages the base-2 offset and translation that efficiently packs the integer value within the minimum set of rows. - -For example, the following `Set()` queries executed against BSI fields will result in the data described in the diagram below: - -``` -Set(1, A=1) -Set(2, A=2) -Set(3, A=3) -Set(4, A=7) -Set(2, B=1) -Set(3, B=6) -``` - -![BSI field diagram](/img/docs/field-bsi.png) -*BSI field diagram* - -Check out this [blog post](/blog/range-encoded-bitmaps/) for some more details about BSI in Pilosa. - - -###### BSI Deprecated Format - -The original implementation of BSI required a fixed bit depth when creating fields because the existence bit was written to the bit above the highest bit. The second version of BSI moves the existence bit to the beginning, adds a negative bit as the second bit, and shifts all remaining bits up by two. - -Pilosa automatically converts all old data to the new format on startup, however, this can cause issues when upgrading Pilosa and then reverting back to an old version. This documentation section exists as a record for anyone who experiences unusual behavior in BSI between versions. - - -#### Time - -Time fields are similar to `set` fields, but in addition to row and column information, they also store a per-bit time value down to a defined granularity. The following example creates a `time` field called "event" which stores timestamp information down to a day granularity. - -``` request -curl localhost:10101/index/repository/field/event \ - -X POST \ - -d '{"options": {"type": "time", "timeQuantum": "YMD"}}' -``` -``` response -{"success":true} -``` - -With `time` fields, data views are generated for each of the defined time segments. For example, for a field with a time quantum of `YMD`, the following `Set()` queries will result in the data described in the diagram below: - -``` -Set(3, A=8, 2017-05-18T00:00) -Set(3, A=8, 2017-05-19T00:00) -``` - -![time quantum field diagram](/img/docs/field-time-quantum.png) -*Time quantum field diagram* - -#### Mutex - -Mutex fields are similar to `set` fields, with the distinction of requiring the row value for each column to be mutually exclusive. In other words, each column can only have a single value for the field. If the field value for a column is updated on a `mutex` field, then the previous field value for that column will be cleared. This field type is like a field in an RDBMS table where every record contains a single value for a particular field. - -#### Boolean - -A boolean field is similar to a `mutex` field tracking only two values: `true` and `false`. Boolean fields do not maintain a sorted cache, nor do they support key values. diff --git a/docs/examples.md b/docs/examples.md deleted file mode 100644 index eae05ab76..000000000 --- a/docs/examples.md +++ /dev/null @@ -1,221 +0,0 @@ -+++ -title = "Examples" -weight = 4 -nav = [ - "Transportation", -] -+++ - -## Examples - -### Transportation - -#### Introduction - -New York City released an extremely detailed data set of over 1 billion taxi rides taken in the city - this data has become a popular target for analysis by tech bloggers and has been very well studied.

These data files have around 20 columns, about half of which are relevant to the benchmark queries we're looking at: - -* Distance: miles, floating point -* Fare: dollars, floating point -* Number of passengers: integer -* Dropoff location: latitude and longitude, floating point -* Pickup location: latitude and longitude, floating point -* Dropoff time: timestamp -* Pickup time: timestamp - -We import these fields, creating one or more Pilosa fields from each of them: - -field |mapping -------------|--------------------- -cab_type |direct map of enum int → row ID -dist_miles |round(dist) → row ID -total_amount_dollars |round(dist) → row ID -passenger_count |direct map of integer value → row ID -drop_grid_id |(lat, lon) → 100x100 rectangular grid → cell ID -drop_year |year(timestamp) → row ID -drop_month |month(timestamp) → row ID -drop_day |day(timestamp) → row ID -drop_time |time of day mapped to one of 48 half-hour buckets -pickup_grid_id |(lat, lon) → 100x100 rectangular grid → cell ID -pickup_year |year(timestamp) → row ID -pickup_month |month(timestamp) → row ID -pickup_day |day(timestamp) → row ID -pickup_time |time of day mapped to one of 48 half-hour buckets → row ID - -We also created two extra fields that represent the duration and average speed of each ride: - -field |mapping ---------------------|------------- -duration_minutes |round(drop_timestamp - pickup_timestamp) → row ID -speed_mph |round(dist_miles / (drop_timestamp - pickup_timestamp)) → row ID - -#### Mapping - -Each column that we want to use must be mapped to a combination of fields and row IDs according to some rule. There are many ways to approach this mapping, and the taxi dataset gives us a good overview of possibilities. - -##### 0 columns → 1 field - -**cab_type**: contains one row for each type of cab. Each column, representing one ride, has a bit set in exactly one row of this field. The mapping is a simple enumeration, for example yellow=0, green=1, etc. The values of the bits in this field are determined by the source of the data. That is, we're importing data from several disparate sources: NYC yellow taxi cabs, NYC green taxi cabs, and Uber cars. For each source, the single row to be set in the cab_type field is constant. - -##### 1 column → 1 field - -The following three fields are mapped in a simple direct way from single columns of the original data. - -**dist_miles:** each row represents rides of a certain distance. The mapping is simple: as an example, row 1 represents rides with a distance in the interval [0.5, 1.5]. That is, we round the floating point value of distance to an integer, and use that as the row ID directly. Generally, the mapping from a floating point value to a row ID could be arbitrary. The rounding mapping is concise to implement, which simplifies importing and analysis. As an added bonus, it's human-readable. We'll see this pattern used several times. - -In PDK parlance, we define a Mapper, which is simply a function that returns integer row IDs. PDK has a number of predefined mappers that can be described with a few parameters. One of these is LinearFloatMapper, which applies a linear function to the input, and casts it to an integer, so the rounding is handled implicitly. In code: -```go -lfm := pdk.LinearFloatMapper{ - Min: -0.5, - Max: 3600.5, - Res: 3601, -} -``` - -`Min` and `Max` define the linear function, and `Res` determines the maximum allowed value for the output row ID - we chose these values to produce a "round to nearest integer" behavior. Other predefined mappers have their own specific parameters, usually two or three. - -This mapper function is the core operation, but we need a few other pieces to define the overall process, which is encapsulated in the ColumnMapper object. This object defines which field(s) of the input data source to use (`Fields`), how to parse them (`Parsers`), what mapping to use (`Mapper`), and the name of the field to use (`Field`). -```go -pdk.ColumnMapper{ - Field: "dist_miles", - Mapper: lfm, - Parsers: []pdk.Parser{pdk.FloatParser{}}, - Fields: []int{fields["trip_distance"]}, -}, -``` - -These same objects are represented in the JSON definition file: -```go -{ - "Fields": { - "Trip_distance": 10 - }, - "Mappers": [ - { - "Name": "lfm0", - "Min": -0.5, - "Max": 3600.5, - "Res": 3600 - } - ], - "ColumnMappers": [ - { - "Field": "dist_miles", - "Mapper": { - "Name": "lfm0" - }, - "Parsers": [ - {"Name": "FloatParser"} - ], - "Fields": "Trip_distance" - } - ] -} -``` - -Here, we define a list of Mappers, each including a name, which we use to refer to the mapper later, in the list of ColumnMappers. We can also do this with Parsers, but a few simple Parsers that need no configuration are available by default. We also have a list of Fields, which is simply a map of field names (in the source data) to column indices (in Pilosa). We use these names in the ColumnMapper definitions to keep things human-readable. - -**total_amount_dollars:** Here we use the rounding mapping again, so each row represents rides with a total cost that rounds to the row's ID. The ColumnMapper definition is very similar to the previous one. - -**passenger_count:** This column contains small integers, so we use one of the simplest possible mappings: the column value is the row ID. - -##### 1 column → multiple fields - -When working with a composite data type like a timestamp, there are plenty of mapping options. In this case, we expect to see interesting periodic trends, so we want to encode the cyclic components of time in a way that allows us to look at them independently during analysis. - -We do this by storing time data in four separate fields for each timestamp: one each for the year, month, day, and time of day. The first three are mapped directly. For example, a ride with a date of 2015/06/24 will have a bit set in row 2015 of field "year", row 6 of field "month", and row 24 of field "day". - -We might continue this pattern with hours, minutes, and seconds, but we don't have much use for that level of precision here, so instead we use a "bucketing" approach. That is, we pick a resolution (30 minutes), divide the day into buckets of that size, and create a row for each one. So a ride with a time of 6:45AM has a bit set in row 13 of field "time_of_day". - -We do all of this for each timestamp of interest, one for pickup time and one for dropoff time. That gives us eight total fields for two timestamps: pickup_year, pickup_month, pickup_day, pickup_time, drop_year, drop_month, drop_day, drop_time. - -##### Multiple columns → 1 field - -The ride data also contains geolocation data: latitude and longitude for both pickup and dropoff. We just want to be able to produce a rough overview heatmap of ride locations, so we use a grid mapping. We divide the area of interest into a 100x100 grid in latitude-longitude space, label each cell in this grid with a single integer, and use that integer as the row ID. - -We do all of this for each location of interest, one for pickup and one for dropoff. That gives us two fields for two locations: pickup_grid_id, drop_grid_id. - -Again, there are many mapping options for location data. For example, we might convert to a different coordinate system, apply a projection, or aggregate locations into real-world regions such as neighborhoods. Here, the simple approach is sufficient. - -##### Complex mappings - -We also anticipate looking for trends in ride duration and speed, so we want to capture this information during the import process. For the field `duration_minutes`, we compute a row ID as `round((drop_timestamp - pickup_timestamp).minutes)`. For the field `speed_mph`, we compute row ID as `round(dist_miles / (drop_timestamp - pickup_timestamp).minutes)`. These mapping calculations are straightforward, but because they require arithmetic operations on multiple columns, they are a bit too complex to capture in the basic mappers available in PDK. Instead, we define custom mappers to do the work: -```go -durm := pdk.CustomMapper{ - Func: func(fields ...interface{}) interface{} { - start := fields[0].(time.Time) - end := fields[1].(time.Time) - return end.Sub(start).Minutes() - }, - Mapper: lfm, -} -``` - -#### Import process - -After designing this schema and mapping, we capture it in a JSON definition file that can be read by the PDK import tool. Running `pdk taxi` runs the import based on the information in this file. For more details, see the [PDK](../pdk/) section, or check out the [code](https://github.com/pilosa/pdk/tree/master/usecase/taxi) itself. - -#### Queries - -Now we can run some example queries. - -Count per cab type can be retrieved, sorted, with a single PQL call. - -```request -TopN(cab_type) -``` -```response -{"results":[[{"id":1,"count":1992943},{"id":0,"count":7057}]]} -``` - -High traffic location IDs can be retrieved with a similar call. These IDs correspond to latitude, longitude pairs, which can be recovered from the mapping that generates the IDs. - -```request -TopN(pickup_grid_id) -``` -```response -{"results":[[{"id":5060,"count":40620},{"id":4861,"count":38145},{"id":4962,"count":35268},...]]} -``` - -Average of `total_amount` per `passenger_count` can be computed with some postprocessing. We use a small number of `TopN` calls to retrieve counts of rides by passenger_count, then use those counts to compute an average. - -```python -import pilosa - -client = pilosa.Client() -schema = client.schema() -taxi = schema.index("taxi") -passenger_count = taxi.field("passenger_count") -total_amount_dollars = taxi.field("total_amount_dollars") - -queries = [] -pcounts = range(10) -for i in pcounts: - queries.append(total_amount_dollars.topn(passenger_count.row(i)) -query = taxi.batch_query(**queries) -results = client.query(query) -resp = requests.post(qurl, data=queries) - -average_amounts = [] -for pcount, result in zip(pcounts, resp.results): - wsum = sum([r.count * r.id for r in result.count_items]) - count = sum([r.count for r in result.count_items]) - average_amounts.append(float(wsum)/count) -``` - -
-Note that the BSI-powered Sum query now provides an alternative approach to this kind of query. -

It supports fast ad-hoc queries and segmentation. Pilosa does not require the underlying data to be moved, rather it can be populated in conjunction with data writes, or it can be backfilled asynchronously from any other data store or event processing system. This allows Pilosa to support sub-second queries against very large underlying data sets. - -### Is Pilosa a database? - -Pilosa is not a database in the traditional sense. While Pilosa does store data (both in-memory as well as persisted to disk), it wouldn't typically be used as a primary data store. Instead, one would likely use Pilosa as an index of the data stored in a traditional database or in a data warehouse. - -### Where does Pilosa fit in my stack? - -Pilosa was designed to index the relationships in your data. Pilosa runs along with your existing stack, integrating with one or more backing data stores. Pilosa can connect through a stream platform like Kafka or application integration via [PDK](../pdk/). - -### How is Pilosa different from Elasticsearch since they are both indexes? - -Elasticsearch is a search engine based on Lucene, and is therefore very good at indexing and searching large volumes of unstructured text. As it matures, Elasticsearch has continued to move into the analytics space, but its core data object is still the "document". Pilosa is specifically designed to index structured data and improve query speed. By representing data as the relationship between objects, and then storing those relationships in bitmaps, Pilosa can very efficiently search and compare many millions of data points while still maintaining a small memory footprint. - -### How do I get my data into Pilosa? - -There are typically two methods for getting data into Pilosa: importing large batches of data from an existing data set, and continuously updating Pilosa as data is added or updated. - -In the first case, one would use the `pilosa import` command to bulk load structured data into Pilosa. In order to improve this process, one can use the Pilosa Development Kit (PDK) to map structured data in the original data set onto the Pilosa schema. - -For the case where data is continually mutating, one would apply a parallel data writer at the point at which data is written to the persistent data store. This new writer would simultaneously write to Pilosa. An example use case would be one where Kafka was employed as the message broker in your data pipeline, you could introduce an additional Kafka consumer to read from the message log and write mutated data to Pilosa. - -### What languages can I use with it? - -There is currently [client support](../client-libraries/) for [Go](https://github.com/pilosa/go-pilosa), [Python](https://github.com/pilosa/python-pilosa), and [Java](https://github.com/pilosa/java-pilosa). If you want to use Pilosa with a different language, you can access Pilosa via the [Pilosa API](../api-reference/). - -### Do you query Pilosa using SQL? - -One can access Pilosa directly via the terminal using the [Pilosa Query Language](../query-language/) (PQL), but a typical implementation would use one of the Pilosa client libraries to integrate with an existing codebase. There is currently client support for Go, Python, and Java. - -### Replication on each node? - -Pilosa supports a replication factor greater than or equal to one. When replication is configured to be greater than one, then all mutations will be replicated to additional nodes in the cluster. For example, in a five-node cluster consisting of nodes A-B-C-D-E and with replication factor of three, then a write to node B will result in data being written to nodes B, C, and D. If the replication factor is greater than the number of nodes in the cluster, the data will be replicated to every node in the cluster only once. diff --git a/docs/getting-started.md b/docs/getting-started.md deleted file mode 100644 index 982bf1ca1..000000000 --- a/docs/getting-started.md +++ /dev/null @@ -1,970 +0,0 @@ -+++ -title = "Getting Started" -weight = 3 -nav = [ - "Starting Pilosa", - "Sample Project", - "Using Curl", - "Using Go", - "Using Java", - "Using Python", - "What's Next?", -] -+++ - -## Getting Started - -Pilosa supports an HTTP interface which uses JSON by default. -Any HTTP tool can be used to interact with the Pilosa server.

- -### Starting Pilosa - -Follow the steps in the [Installation](../installation/) document to install Pilosa. -Execute the following in a terminal to run Pilosa with the default configuration (Pilosa will be available at [localhost:10101](http://localhost:10101)): -``` -pilosa server -``` - -Let's make sure Pilosa is running: -``` request -curl localhost:10101/status -``` -``` response -{"state":"NORMAL","nodes":[{"id":"91715a50-7d50-4c54-9a03-873801da1cd1","uri":{"scheme":"http","host":"localhost","port -":10101},"isCoordinator":true}],"localID":"91715a50-7d50-4c54-9a03-873801da1cd1"} -``` - -### Sample Project - -In order to better understand Pilosa's capabilities, we will create a sample project called "Star Trace" containing information about 1,000 popular Github repositories which have "go" in their name. The Star Trace index will include data points such as programming language and stargazers—people who have starred a project. - -Although Pilosa doesn't keep the data in a tabular format, we still use the terms "columns" and "rows" when describing the data model. We put the primary objects in columns, and the properties of those objects in rows. For example, the Star Trace project will contain an index called "repository" which contains columns representing Github repositories, and rows representing properties like programming languages and stargazers. We can better organize the rows by grouping them into sets called Fields. So the "repository" index might have a "languages" field as well as a "stargazers" field. You can learn more about indexes and fields in the [Data Model](../data-model/) section of the documentation. - -

If at any time you want to verify the data structure, you can request the schema as follows:

-
- -```request -curl localhost:10101/schema -``` -```response -{ - "indexes": [ - { - "name": "repository", - "options": { - "keys": false, - "trackExistence": true - }, - "fields": [ - { - "name": "language", - "options": { - "type": "set", - "cacheType": "ranked", - "cacheSize": 50000, - "keys": false - } - }, - { - "name": "stargazer", - "options": { - "type": "time", - "timeQuantum": "YMDH", - "keys": false, - "noStandardView": false - } - } - ], - "shardWidth": 1048576 - } - ] -} -``` -

- -#### Using Curl - -##### Create the Schema - -Before we can import data or run queries, we need to create our indexes and the fields within them. Let's create the `repository` index first: -``` request -curl localhost:10101/index/repository -X POST -``` -``` response -{"success":true} -``` -The index name must be 230 characters or fewer, start with a letter, and consist only of lowercase alphanumeric characters or `_-`. The same goes for field names. - -Let's create the `stargazer` field which has user IDs of stargazers as its rows: -``` request -curl localhost:10101/index/repository/field/stargazer \ - -X POST \ - -d '{"options": {"type": "time", "timeQuantum": "YMD"}}' -``` -``` response -{"success":true} -``` - -Since our data contains time stamps which represent the time users starred repos, we set the field type to `time`. Time quantum is the resolution of the time we want to use, and we set it to `YMD` (year, month, day) for `stargazer`. - -Next up is the `language` field, which will contain IDs for programming languages: -``` request -curl localhost:10101/index/repository/field/language \ - -X POST -``` -``` response -{"success":true} -``` - -The `language` is a `set` field, but since the default field type is `set`, we didn't specify it in field options. - -##### Import Data From CSV Files - -Download the `stargazer.csv` and `language.csv` files here: - -``` -curl -O https://raw.githubusercontent.com/pilosa/getting-started/master/stargazer.csv -curl -O https://raw.githubusercontent.com/pilosa/getting-started/master/language.csv -``` - -Run the following commands to import the data into Pilosa: - -``` -pilosa import -i repository -f stargazer stargazer.csv -pilosa import -i repository -f language language.csv -``` - -If you are using a Docker container for Pilosa (with name `pilosa`), you should instead copy the `*.csv` file into the container and then import them: -``` -docker cp stargazer.csv pilosa:/stargazer.csv -docker exec -it pilosa /pilosa import -i repository -f stargazer /stargazer.csv -docker cp language.csv pilosa:/language.csv -docker exec -it pilosa /pilosa import -i repository -f language /language.csv -``` - -Note that both the user IDs and the repository IDs were remapped to sequential integers in the data files, they don't correspond to actual Github IDs anymore. You can check out [languages.txt](https://github.com/pilosa/getting-started/blob/master/languages.txt) to see the mapping for languages. - -##### Make Some Queries - -Which repositories did user 14 star: -``` request -curl localhost:10101/index/repository/query \ - -X POST \ - -d 'Row(stargazer=14)' -``` -``` response -{ - "results":[ - { - "attrs":{}, - "columns":[1,2,3,362,368,391,396,409,416,430,436,450,454,460,461,464,466,469,470,483,484,486,490,491,503,504,514] - } - ] -} -``` - -What are the top 5 languages in the sample data: -``` request -curl localhost:10101/index/repository/query \ - -X POST \ - -d 'TopN(language, n=5)' -``` -``` response -{ - "results":[ - [ - {"id":5,"count":119}, - {"id":1,"count":50}, - {"id":4,"count":48}, - {"id":9,"count":31}, - {"id":13,"count":25} - ] - ] -} -``` - -Which repositories were starred by user 14 and 19: -``` request -curl localhost:10101/index/repository/query \ - -X POST \ - -d 'Intersect( - Row(stargazer=14), - Row(stargazer=19) - )' -``` -``` response -{ - "results":[ - { - "attrs":{}, - "columns":[2,3,362,396,416,461,464,466,470,486] - } - ] -} -``` - -Which repositories were starred by user 14 or 19: -``` request -curl localhost:10101/index/repository/query \ - -X POST \ - -d 'Union( - Row(stargazer=14), - Row(stargazer=19) - )' -``` -``` response -{ - "results":[ - { - "attrs":{}, - "columns":[1,2,3,361,362,368,376,377,378,382,386,388,391,396,398,400,409,411,412,416,426,428,430,435,436,450,452,453,454,456,460,461,464,465,466,469,470,483,484,486,487,489,490,491,500,503,504,505,512,514] - } - ] -} -``` - -Which repositories were starred by user 14 and 19 and also were written in language 1: -``` request -curl localhost:10101/index/repository/query \ - -X POST \ - -d 'Intersect( - Row(stargazer=14), - Row(stargazer=19), - Row(language=1) - )' -``` -``` response -{ - "results":[ - { - "attrs":{}, - "columns":[2,362,416,461] - } - ] -} -``` - -Set user 99999 as a stargazer for repository 77777: -``` request -curl localhost:10101/index/repository/query \ - -X POST \ - -d 'Set(77777, stargazer=99999)' -``` -``` response -{"results":[true]} -``` - -Please note that while user ID 99999 may not be sequential with the other column IDs, it is still a relatively low number. -Don't try to use arbitrary 64-bit integers as column or row IDs in Pilosa - this will lead to problems such as poor performance and out of memory errors. - -#### Using Go - -Pilosa follows the Go policy of supporting the two most recent major versions of Go. - -##### Create the Environment - -Interacting with Pilosa in your go program is best accomplished using our client, go-pilosa. To install go-pilosa, open a new terminal and download the library to your `GOPATH` using: -``` -go get github.com/pilosa/go-pilosa -``` - -Create a project folder: -``` -mkdir getting-started && cd getting-started -``` - -In this folder, we will download two CSV files to provide data to our fields later on. Download the `stargazer.csv` and `language.csv` files here: -``` -curl -O https://raw.githubusercontent.com/pilosa/getting-started/master/stargazer.csv -curl -O https://raw.githubusercontent.com/pilosa/getting-started/master/language.csv -``` - -We will also create a file called `startrace.go` as follows: -``` -touch startrace.go -``` -This file will be used in the following sections. - -##### Create the Schema - -Before we can import data or run queries, we need to create our schema. You can see two imports from the go-pilosa repo, go-pilosa for the client, and csv for the CSV reader. Create the schema by creating a client (which will communicate our schema to Pilosa), creating a schema locally (which will contain our indexes and fields), and syncing with Pilosa. This is all done in the `startrace.go` file: -``` -package main - -import ( - "bytes" - "fmt" - "github.com/pilosa/go-pilosa" - "github.com/pilosa/go-pilosa/csv" - "io/ioutil" - "log" -) - -func main() { - // Create the Schema - client := pilosa.DefaultClient() - schema, _ := client.Schema() - // This is where the index will go later - // This is where the fields will go later - err := client.SyncSchema(schema) - if err != nil { - log.Fatal(err) - } -} -``` - -Next, let's create the `repository` index: -``` - repository := schema.Index("repository") -``` - -The index name must be 230 characters or fewer, start with a letter, and consist only of lowercase alphanumeric characters or `_-`. The same goes for field names. - -Let's create the `stargazer` field which has user IDs of stargazers as its rows: -``` - stargazer := repository.Field("stargazer") -``` - -Next up is the `language` field, which will contain IDs for programming languages: -``` - language := repository.Field("language") -``` - -Your `startrace.go` file should look like: -``` -package main - -import ( - "bytes" - "fmt" - "github.com/pilosa/go-pilosa" - "github.com/pilosa/go-pilosa/csv" - "io/ioutil" - "log" -) - -func main() { - // Create the Schema - client := pilosa.DefaultClient() - schema, _ := client.Schema() - repository := schema.Index("repository") - stargazer := repository.Field("stargazer") - language := repository.Field("language") - err := client.SyncSchema(schema) - if err != nil { - log.Fatal(err) - } -} -``` - -##### Import Data From CSV Files - -Now that we have our index and our fields, we can import the data we downloaded earlier and be on our way to making our own queries. - -First, we will load our data into the `stargazer` field: -``` - stargazerFile, err := ioutil.ReadFile("stargazer.csv") - if err != nil { - log.Fatal(err) - } - format := "2006-01-02T15:04" - iterator = csv.NewColumnIteratorWithTimestampFormat(csv.RowIDColumnID, bytes.NewReader(stargazerFile), format) - err = client.ImportField(stargazer, iterator) - if err != nil { - log.Fatal(err) - } -``` -Since our `stargazer` data contains time stamps, which represent the time users starred repos, we will be using the `csv.NewColumnIteratorWithTimeStampFormat` function from the go-pilosa/csv package. This function takes the format of the csv files (`csv.RowIDColumnID`), an `io.Reader` (`bytes.NewReader(stargazerFile)`), and the time quantum format (`format`) and translates the csv file into a format Pilosa can read. Time quantum is the resolution of the time we want to use. - -Next, we will load our data into the `language` field: -``` - languageFile, err := ioutil.ReadFile("language.csv") - if err != nil { - log.Fatal(err) - } - iterator := csv.NewColumnIterator(csv.RowIDColumnID, bytes.NewReader(languageFile)) - err = client.ImportField(language, iterator) - if err != nil { - log.Fatal(err) - } -``` -Since our `language` data doesn't contain time stamps, we will use the `csv.NewColumnIterator` function in place of `csv.NewColumnIteratorWithTimeStampFormat`. - -Note that both the user IDs and the repository IDs were remapped to sequential integers in the data files, they don't correspond to actual Github IDs anymore.

You can see the first six dependencies are imported from the java-pilosa library. Create the schema by creating a client which will communicate our schema to Pilosa, creating a schema which will contain our indexes and fields, and syncing with Pilosa. This is all done in the `StarTrace.java` file: -``` -package main.java; - -import com.pilosa.client.PilosaClient; -import com.pilosa.client.QueryResponse; -import com.pilosa.client.exceptions.PilosaException; -import com.pilosa.client.orm.*; -import com.pilosa.client.csv.FileRecordIterator; -import com.pilosa.client.TimeQuantum; - -import java.io.IOException; -import java.text.SimpleDateFormat; - -public class StarTrace { - public static void main(String []args) throws IOException { - // Create the Schema - PilosaClient client = PilosaClient.defaultClient(); - Schema schema = client.readSchema(); - // This is were the index will go later - // This is were the fields will go later - client.syncSchema(schema); - } -} -``` - -Next, let's create the `repository` index: -``` - Index repository = schema.index("repository"); -``` -The index name must be 230 characters or fewer, start with a letter, and consist only of lowercase alphanumeric characters or `_-`. The same goes for field names. - -Let's create the `stargazer` field which has user IDs of stargazers as its rows: -``` - FieldOptions stargazerOptions = FieldOptions.builder() - .fieldTime(TimeQuantum.YEAR_MONTH_DAY) - .build(); - Field stargazer = repository.field("stargazer", stargazerOptions); -``` -Since our data contains time stamps which represent the time users starred repos, we set the field type to `time` using `fieldTime()`. Time quantum is the resolution of the time we want to use, and we set it to `YEAR_MONTH_DAY` for `stargazer`. - -Next up is the `language` field, which will contain IDs for programming languages: -``` - Field language = repository.field("language"); -``` -The `language` field is a `set` field, but since the default field type is `set`, we don't need to specify it - -Your `StarTrace.java` file should look like: -``` -package main.java; - -import com.pilosa.client.PilosaClient; -import com.pilosa.client.QueryResponse; -import com.pilosa.client.exceptions.PilosaException; -import com.pilosa.client.orm.*; -import com.pilosa.client.csv.FileRecordIterator; -import com.pilosa.client.TimeQuantum; - -import java.io.IOException; -import java.text.SimpleDateFormat; - -public class StarTrace { - public static void main(String []args) throws IOException { - // Create the Schema - PilosaClient client = PilosaClient.defaultClient(); - Schema schema = client.readSchema(); - Index repository = schema.index("repository"); - - FieldOptions stargazerOptions = FieldOptions.builder() - .fieldTime(TimeQuantum.YEAR_MONTH_DAY) - .build(); - Field stargazer = repository.field("stargazer", stargazerOptions); - - Field language = repository.field("language"); - client.syncSchema(schema); - } -} -``` - -##### Import Data From CSV Files - -Now that we have our index and our fields, we can import the data we downloaded earlier and be on our way to making our own queries. - -First, we will load our data into the `stargazer` field: -``` - SimpleDateFormat timestampFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm"); - FileRecordIterator iterator = FileRecordIterator.fromPath("stargazer.csv", stargazer, timestampFormat); - client.importField(stargazer, iterator); -``` -Due to the time aspect of the `stargazer` csv file, we have to specify the time stamp format in the `fromPath` function. We set the variable `timestampFormat` to the format present in the csv file using the function `SimpleDateFormat()` and pass the variable to the `fromPath` function, which will take the csv file name, the field name, and the time stamp format and translate the csv file into a format Pilosa can read. - -Next, we will load our data into the `language` field: -``` - iterator = FileRecordIterator.fromPath("language.csv", language); - client.importField(language, iterator); -``` -Since our `language` data doesn't have a time aspect, the time stamp format doesn't need to be specified. - -Note that both the user IDs and the repository IDs were remapped to sequential integers in the data files, they don't correspond to actual Github IDs anymore.

For more information, see [data model](../data-model/) and [Creating fields](../api-reference/#create-field). - -[Frame](../data-model/#field): Prior to Pilosa 1.0, fields were known as frames. - -[Gossip](https://en.wikipedia.org/wiki/Gossip_protocol): A protocol used by Pilosa for internal communication. - -[GroupBy](../query-language/#group-by): A [PQL](#pql) query, with functionality similar to a SQL `GROUP BY` clause, that returns the count of the intersection of every combination of rows taking one row each from the specified `Rows` calls. GroupBy can be thought of as a multi-dimensional version of the [TopN](#topn) query. - -[Index](../data-model/#index): An Index is a top level container in Pilosa, analogous to a database in an RDBMS. Basic queries cannot operate across multiple indexes. - -[Jump Consistent Hash](https://arxiv.org/pdf/1406.2294v1.pdf): A fast, minimal memory, consistent hash algorithm that evenly distributes the workload even when the number of buckets changes. - -[Max](../query-language/#max): A [PQL](#pql) query that returns the maximum integer value stored in an [integer](#bsi) [field](#field). - -MaxShard: The total number of [shards](#shard) allocated to handle the current set of [columns](#column). This value is important for all [nodes](#node) to efficiently distribute queries. MaxShard is zero-indexed, so if an index contains six shards, its MaxShard will be 5. - -[Min](../query-language/#min): A [PQL](#pql) query that returns the minimum integer value stored in an [integer](#bsi) [field](#field). - -Node: An individual running instance of Pilosa server which belongs to a [cluster](#cluster). - -Partition: The [consistent hash](#jump-consistent-hash) maps keys to partitions (or locations on the unit circle), based on a preset maximum number of partitions. Partitions are then evenly mapped to physical [nodes](#node). To add nodes to the [cluster](#cluster), the partitions must be remapped, and data is then associated across the new cluster topology. `DefaultPartitionN` is 256. It can be modified, but only at compile time, and before ingesting any data. - -[PQL](../query-language/): Pilosa Query Language. - -[Protobuf](https://developers.google.com/protocol-buffers/): Protocol Buffers is a binary serialization format which Pilosa uses for internal messages, and can be used by clients as an alternative to JSON. - -[Replica](../configuration/#cluster-replicas): A copy of a [fragment](#fragment) on a different [node](#node) than the original. The `cluster.replicas` configuration parameter determines how many replicas of a fragment exist in the cluster. This includes the original, so a value of 1 means no extra copies are made. - -[Roaring Bitmap](http://roaringbitmap.org): the compressed bitmap format which Pilosa uses to [implement bitmaps](../architecture/#roaring-bitmap-storage-format), for both storage and logical query operations. - -[Row](../data-model/#row): Rows are the fundamental vertical data axis within Pilosa. They are namespaced to each [field](#field) within an [index](#index). Represented as a [Bitmap](#bitmap). - -[Row (Ranged)](../query-language/#row-range): A [PQL](#pql) query that returns bits based on comparison to timestamps, set according to the [time quantum](#time-quantum). - -[Row (BSI)](../query-language/#row-bsi): A [PQL](#pql) query that returns bits based on comparison to integers stored in [BSI](#bsi) [fields](#field). - -[Rows](../query-language/#rows): A [PQL](#pql) query that returns a list of row IDs in the given field which have at least one bit set. The field argument is mandatory, the others are optional. `Rows` is the primary argument used with the [GroupBy](#groupby) query. - -[Slice](../data-model/#shard): Prior to Pilosa 1.0, shards were known as slices. - -[Shard](../data-model/#shard): [Columns](#column) are [sharded](https://en.wikipedia.org/wiki/Shard_(database_architecture)) on a preset [width](#shardwidth). Shards are operated on in parallel and are evenly distributed across the cluster via a [consistent hash](#jump-consistent-hash). - -ShardWidth: This is the number of [columns](#column) in a [shard](#shard). `ShardWidth` defaults to 220 or about one million. It can be modified, but only at compile time, and before ingesting any data. - -[Sum](../query-language/#sum): A [PQL](#pql) query that returns the sum of integers stored in an [integer](#bsi) [field](#field). - -[Time quantum](../data-model/#time-quantum): Defines the granularity to be used for [ranged Row](#range) queries on time [fields](#field). - -[TOML](https://github.com/toml-lang/toml): the language used for Pilosa's [configuration file](../configuration/). - -[TopN](../query-language/#topn): A [PQL](#pql) query that returns a list of rows, sorted by the count of [columns](#column) set in the [row](#row), within a specified [field](#field). - -View: Views separate the different data layouts within a [Field](#field). The primary view is standard, which represents the typical [row](#row)/[column](#column) data. Time based field views are automatically generated for each [time quantum](#time-quantum). Views are internally managed by Pilosa, and never exposed directly via the API. This simplifies the functional interface by separating it from the physical data representation. diff --git a/docs/installation.md b/docs/installation.md deleted file mode 100644 index f3bf96c44..000000000 --- a/docs/installation.md +++ /dev/null @@ -1,382 +0,0 @@ -+++ -title = "Installation" -weight = 2 -nav = [ - "Installing on MacOS", - "Installing on Linux", -] -+++ - - -## Installation - -Pilosa is currently available for [MacOS](#installing-on-macos) and [Linux](#installing-on-linux). - -### Installing on MacOS - -There are four ways to install Pilosa on MacOS: Use [Homebrew](https://brew.sh/) (recommended), download the binary, build from source, or use [Docker](#docker). - -#### Use Homebrew - -1.

Each -record from Kafka is assigned a Pilosa column, and each value in a record is -assigned a row or field. Pilosa field names are built from the "path" through -the record to arrive at that field. For example: - -```json -{ - "name": "jill", - "favorite_foods": ["corn chips", "chipotle dip"], - "location": { - "city": "Austin", - "state": "Texas", - "latitude": 3754, - "longitude": 4526 - }, - "active": true, - "age": 27 -} -``` - -This JSON object would result in the following Pilosa schema: - -| Field | Example Value | Type | Cache Size | -|----------------|---------------|--------|------------| -| name | "jill" | ranked | 100000 | -| favorite_foods | "corn chips" | ranked | 100000 | -| default | | ranked | 100000 | -| age | 27 | int | | -| location | | ranked | 1000 | -| latitude | 3754 | int | | -| longitude | 4526 | int | | -| location-city | "Austin" | ranked | 100000 | -| location-state | "Texas" | ranked | 100000 | - -All set fields are created as ranked fields by default, with the cache size -listed above.

Field names are a dash-separated concatenation of -all key values in the path - you can see this with fields like location-city. - - -Most of the options to `pdk kafka` are self-explanatory (kafka hosts, pilosa hosts, -kafka topics, kafka group, etc.), but there are a few options that give some -control over the way data is indexed, and ingestion performance. - -* `--batch-size`: The batch size controls how many set bits or values are batched up to be imported *per field*. So for fields that have one value per record, you have to wait for `batch-size` records to come through before you'll see the data indexed in Pilosa. Fields like `favorite_foods` which can have multiple values could be indexed sooner. -* `--framer.collapse`: This is a list of strings which will be removed from the field names created by dash-concatentating all names in the JSON path to a value. E.G. if "location" were listed in `framer.collapse`, then there would be fields named "city" and "state" rather than "location-city" and "location-state". -* `--framer.ignore`: This allows you to skip indexing on any path containing these strings. If you have a field like email address or some other unique ID, you might not want to index it. -* `--subject-path`: If nothing is passed for this option, then each record will be assigned a unique sequential column ID. If `subject-path` is specified, then the value at this path in the record will be mapped to a column ID. If the same value appears in another record, the same column ID will be used. -* `--proxy`: The PDK ingests data, but also keeps a mapping for string values to row IDs, and from subjects to column ids. Because of this, querying Pilosa directly may not be useful, since it only returns integer row and column ids. The PDK will start a proxy server which intercepts requests to Pilosa using strings for row and column ids, and translates them to the integers that Pilosa understands. It will also translate responses so that (e.g.) a TopN query will return `{"results":[[{"Key":"chipotle dip","Count":1},{"Key":"corn chips","Count":1}]]}`. By default, the mapping is stored in an embedded leveldb. - -For more information on running `pdk kafka` and how Pilosa interfaces with Kafka, please see the [kafka directory](https://github.com/pilosa/pdk/tree/master/kafka) in the pdk repository. - -### Library - -For now, the [Godocs](https://godoc.org/github.com/pilosa/pdk) have the most up to date library documentation. - diff --git a/docs/query-language.md b/docs/query-language.md deleted file mode 100644 index 8513cffbc..000000000 --- a/docs/query-language.md +++ /dev/null @@ -1,1060 +0,0 @@ -+++ -title = "Query Language" -weight = 6 -nav = [ - "Conventions", - "Arguments and Types", - "Write Operations", - "Read Operations", -] -+++ - -## Query Language - -### Overview - -This section will provide a detailed reference and examples for the Pilosa Query Language (PQL).

Valid field names are lower case strings; they start with a lowercase letter, and contain only alphanumeric characters and `_-`. They must be 230 characters or less in length. -* `TIMESTAMP` This is a timestamp in the following format `YYYY-MM-DDTHH:MM` (e.g. 2006-01-02T15:04). -* `UINT` An unsigned integer (e.g. 42839). -* `BOOL` A boolean value, `true` or `false`. -* `ATTR_NAME` Must be a valid identifier `[A-Za-z][A-Za-z0-9._-]*`. -* `ATTR_VALUE` Can be a string, float, integer, or bool. -* `CALL` Any query. -* `ROW_CALL` Any query which returns a row, such as `Row`, `Union`, `Difference`, `Xor`, `Intersect`, `Not`. -* `ROWS_CALL` A query that returns a `Rows` result (i.e. a list of row IDs). Currently only the `Rows` query. -* `ROWSET_CALL` A query that returns a set of rows. Currently only the `Rows` and `TopN` queries. -* `[]ATTR_VALUE` Denotes an array of `ATTR_VALUE`s. (e.g. `["a", "b", "c"]`). - -### Write Operations - -#### Set - -**Spec:** - -``` -Set(, =, [TIMESTAMP]) -``` - -**Description:** - -`Set` assigns a value of 1 to a bit in the binary matrix, thus associating the given row (the `` value) in the given field with the given column. - -
-

While using "Set" in PQL is a convenient way to get familiar with Pilosa, it's almost always better to use the import functionality in the Go, Java, and Python clients to ingest lots of data.

-
- -**Result Type:** boolean - -A return value of `true` indicates that the bit was changed to 1. - -A return value of `false` indicates that the bit was already set to 1 and nothing changed. - - -**Examples:** - -Set the bit at row 1, column 10: -```request -Set(10, stargazer=1) -``` -```response -{"results":[true]} -``` - -This sets a bit in the stargazer field, representing that the user with id=1 has starred the repository with id=10. - -Set also supports providing a timestamp. To write the date that a user starred a repository: -```request -Set(10, stargazer=1, 2016-01-01T00:00) -``` -```response -{"results":[true]} -``` - -Set multiple bits in a single request: -```request -Set(10, stargazer=1) Set(20, stargazer=1) Set(10, stargazer=2) Set(30, stargazer=2) -``` -```response -{"results":[false,true,true,true]} -``` - -Set the field "pullrequests" to integer value 2 at column 10: -```request -Set(10, pullrequests=2) -``` -```response -{"results":[true]} -``` - -#### SetRowAttrs -**Spec:** - -``` -SetRowAttrs(, , - , - [ATTR_NAME=ATTR_VALUE ...]) -``` - -**Description:** - -`SetRowAttrs` associates arbitrary key/value pairs with a row in a field. Setting a value of `null`, without quotes, deletes an attribute. - -**Result Type:** null - -SetRowAttrs queries always return `null` upon success. - -**Examples:** - -Set attributes `username` and `active` on row 10: -```request -SetRowAttrs(stargazer, 10, username="mrpi", active=true) -``` -```response -{"results":[null]} -``` - -Set username value and active status for user 10. These are arbitrary key/value pairs which have no meaning to Pilosa. You can see the attributes you've set on a row with a [Row](../query-language/#row) query like so `Row(stargazer=10)`. - -Delete attribute `username` on row 10: -```request -SetRowAttrs(stargazer, 10, username=null) -``` -```response -{"results":[null]} -``` - -#### SetColumnAttrs - -**Spec:** - -``` -SetColumnAttrs(, - , - [ATTR_NAME=ATTR_VALUE ...]) -``` - -**Description:** - -`SetColumnAttrs` associates arbitrary key/value pairs with a column in an index. - -**Result Type:** null - -SetColumnAttrs queries always return `null` upon success. Setting a value of `null`, without quotes, deletes an attribute. - -**Examples:** - -Set attributes `stars`, `url`, and `active` on column 10: -```request -SetColumnAttrs(10, stars=123, url="http://projects.pilosa.com/10", active=true) -``` -```response -{"results":[null]} -``` - -Set url value and active status for project 10. These are arbitrary key/value pairs which have no meaning to Pilosa. - -ColumnAttrs can be requested by adding the URL parameter `columnAttrs=true` to a query. For example: -```request -curl localhost:10101/index/repository/query?columnAttrs=true -XPOST -d 'Row(stargazer=1) Row(stargazer=2)' -``` -```response -{ - "results":[ - {"attrs":{},"cols":[10,20]}, - {"attrs":{},"cols":[10,30]} - ], - "columnAttrs":[ - {"id":10,"attrs":{"active":true,"stars":123,"url":"http://projects.pilosa.com/10"}}, - {"id":20,"attrs":{"active":false,"stars":456,"url":"http://projects.pilosa.com/30"}} - ] -} -``` - -In this example, ColumnAttrs have been set on columns 10 and 20, but not column 30. The relevant attributes are all returned in a single columnAttrs list. See the [query index](../api-reference/#query-index) section for more information. - -Delete the `url` attribute on column 10: -```request -SetColumnAttrs(10, url=null) -``` -```response -{"results":[null]} -``` - -#### Clear - -**Spec:** - -``` -Clear(, =) -``` - -**Description:** - -`Clear` assigns a value of 0 to a bit in the binary matrix, thus disassociating the given row in the given field from the given column. - -Note that clearing a column on a time field will remove all data for that column. - -**Result Type:** boolean - -A return value of `true` indicates that the bit was toggled from 1 to 0. - -A return value of `false` indicates that the bit was already set to 0 and nothing changed. - -**Examples:** - -Clear the bit at row 1 and column 10 in the stargazer field: -```request -Clear(10, stargazer=1) -``` -```response -{"results":[true]} -``` - -This represents removing the relationship between the user with id=1 and the repository with id=10. - -#### ClearRow - -**Spec:** - -``` -ClearRow(=) -``` - -**Description:** - -`ClearRow` sets all bits to 0 in a given row of the binary matrix, thus disassociating the given row in the given field from all columns. - -**Result Type:** boolean - -A return value of `true` indicates that at least one column was toggled from 1 to 0. - -A return value of `false` indicates that all bits in the row were already 0 and nothing changed. - -**Examples:** - -Clear all bit in row 1 in the stargazer field: -```request -ClearRow(stargazer=1) -``` -```response -{"results":[true]} -``` - -This represents removing the relationship between the user with id=1 and all repositories. - -#### Store - -**Spec:** - -``` -Store(, =) -``` - -**Description:** - -`Store` writes the results of `` to the specified row.

The exact solution to the problem of computing the TopN counts is prohibitively expensive, so TopN is instead implemented as a heuristic. This provides a significant performance improvement, at the cost of uncertainty in the result order. - -The implementation is based on a per-shard cache. The accuracy of the results depends on how well the counts for the overall index are reflected in the individual shards (so TopN queries on a single-shard index are exact). If the distribution of bits across shards is uniform, shard counts are representative. This is often a reasonable assumption, especially for the top results for large data sets, in which counts might follow Zipfian, exponential, or other long-tail distributions. However, this assumption may not hold for some applications. - -Additional implementation details: - -* The field's cache size determines the number of sorted rows to maintain in the cache for purposes of TopN queries. There is a tradeoff between performance and accuracy; increasing the cache size will improve accuracy of results at the cost of performance. Note that this per-shard tradeoff is independent of the per-index performance/accuracy tradeoff mentioned above. -* Fields with cache type `ranked` will return the top rows sorted by count in descending order. -* Fields with cache type `lru` will maintain an LRU (Least Recently Used replacement policy) cache, thus a TopN query on this type of field will return rows sorted in order of most recently set bit. -* Once full, the cache will truncate the set of rows according to the field option CacheSize. Rows that straddle the limit and have the same count will be truncated in no particular order. -* The TopN query's attribute filter is applied to the existing sorted cache of rows. Rows that fall outside of the sorted cache range, even if they would normally pass the filter, are ignored. - -See [field creation](../api-reference/#create-field) for more information about the cache. - -**Examples:** - -Basic TopN query: -```request -TopN(stargazer) -``` -```response -{"results":[[{"id":1240,"count":102},{"id":4734,"count":100},{"id":12709,"count":93},...]]} -``` - -* `id` is a row ID (user ID) -* `count` is a count of columns (repositories) -* Results are the number of bits set in the corresponding row (repositories that each user starred) in descending order for all rows (users) in the stargazer field. For example user 1240 starred 102 repositories, user 4734 starred 100 repositories, user 12709 starred 93 repository. - -Limit the number of results: -```request -TopN(stargazer, n=2) -``` -```response -{"results":[[{"id":1240,"count":102},{"id":4734,"count":100}]]} -``` - -* Results are the top two rows (users) sorted by number of bits set (repositories they've starred) in descending order. - -Filter based on an existing row: -```request -TopN(stargazer, Row(language=1), n=2) -``` -```response -{"results":[[{"id":1240,"count":35},{"id":7508,"count":32}]]} -``` - -* Results are the top two users (rows) sorted by the number of bits set in the intersection with row 1 of the language field (repositories that they've starred which are written in language 1). - -Filter based on attributes: -```request -TopN(stargazer, n=2, attrName=active, attrValues=[true]) -``` -```response -{"results":[[{"id":10,"count":1},{"id":13,"count":1}]]} -``` - -* Results are the top two users (rows) which have the "active" attribute set to "true", sorted by the number of bits set (repositories that they've starred). - - -#### Min - -**Spec:** - -``` -Min([ROW_CALL], field=) -``` - -**Description:** - -Returns the minimum value of all BSI integer values in this `field`.

The field argument is mandatory, the others are optional. - -If `previous` is given, rows prior to and including the specified row ID or -key will not be returned. If `column` is given, only rows which have a set bit -in the given column will be returned. `previous` or `column` must be strings if -and only if the field or index respectively is using key translation. If `limit` -is given, the number of rowIDs returned will be less than or equal to -`limit`. The combination of `limit` and `previous` allows for paging over large -result sets. Results are always ordered, so setting `previous` as the last -result of the previous request will start from the next available row. - -If the field is of type `time`, the `from` and `to` arguments can be provided -to restrict the result to a specific time span. If `from` and `to` are -not provided, the full range of existing data will be queried. - -If `like` is given, only keys matching a pattern will be selected. -A `like` pattern may use `_` as a placeholder to match a single UTF-8 codepoint, and `%` to match 0 or more codepoints. -All other characters will be matched exactly. - -**Result Type:** Object with `"rows" or "keys" and an array of integers or strings respectively.` - -**Examples:** - -Without keys: -```request -Rows(age) -``` -```response -{"rows":[18,22,29]} -``` - -With keys: -```request -Rows(job) -``` -```response -{"rows":null,"keys":["engineer","management","student"]} -``` - -With `like`: -```request -Rows(job, like="%t") -``` -```response -{"rows":null,"keys":["management","student"]} -``` - -#### Extract - -**Spec:** -``` -Extract(, [...]) -``` - -**Description:** - -Extract intersects a set of columns with a set of rows in order to extract a subset of the index. -The result is a table consisting of the matched columns and the rows which they intersect. -This is similar to a select query in a SQL database. - -**Result Type:** Object with an array of the selected fields and an array of the selected columns. -The column array contains objects containing a column identifier and an array of field values. -Field values are typed as such: -- Bool Field - boolean or null -- Mutex Field (unkeyed) - 64-bit unsigned integer or null -- Mutex Field (keyed) - string or null -- Integer Field - 64-bit signed integer or null -- Decimal Field - Pilosa decimal value or null -- Set Field (unkeyed) - array of 64-bit unsigned integers -- Set Field (keyed) - array of strings -- Time Field - same as the equivalent Set - -**Examples:** - -List all stargazers who have starred repository 1, and the full set of repositories they have starred: -```request -Extract(Row(stargazer=1), Rows(stargazer)) -``` -```response -{"fields":[{"name":"stargazer","type":"set"}],"columns":[{"column":3,"rows":[[1, 2, 3]]}]} -``` - -#### Group By - -**Spec:** - -``` -GroupBy(, [...], limit=, filter=, aggregate=) -``` - -**Description:** - -GroupBy returns the count of the intersection of every combination of rows -taking one row each from the specified `Rows` calls. It returns only those -combinations for which the count is greater than 0. - -The optional `filter` argument takes any type of `Row` query (e.g. Row, Union, -Intersect, etc.) which will be intersected with each result prior to returning -the count. This is analagous to a WHERE clause applied to a relational GROUP BY -query. - -The optional `limit` argument limits the number of results returned. The results -are ordered, so as long as the data isn't changing, the same query will return -the same result set. - -The optional `aggregate` argument takes a `Sum()` query which will be used to -calculate the sum & count of each group. This is similar to using a `SUM()` in -the SELECT clause of a relation GROUP BY query. - -Paging through results is supported by passing the `previous` argument to each -of the `Rows` calls in the GroupBy. Take the last result from your previous -`GroupBy` query, and pass each row ID in that result as the `previous` argument -to each of the respective `Rows` queries in your next `GroupBy` query. - -**Result Type:** Array of "groups". Each group is an object with a group key and -a count key.

- -### Setting Up a Secure Cluster - -#### Introduction - -Pilosa supports encrypting all communication with nodes in a cluster using TLS, including [Mutual TLS Authentication](https://en.wikipedia.org/wiki/Mutual_authentication). In this tutorial, we will be setting up a three node Pilosa cluster running on the same computer. The same steps can be used for a multi-computer cluster but that requires setting up firewalls and other platform-specific configuration which is beyond the scope of this tutorial. - -This tutorial assumes that you are using a UNIX-like system, such as Linux or MacOS. [Windows Subsystem for Linux (WSL)](https://msdn.microsoft.com/en-us/commandline/wsl/about) works equally well on Windows 10 systems. - -#### Installing Pilosa and Creating the Directory Structure - -If you haven't already done so, install Pilosa server on your computer. For Linux and WSL (Windows Subsystem for Linux) use the [Installing on Linux](../installation/#installing-on-linux) instructions. For MacOS use the [Installing on MacOS](../installation/#installing-on-macos). We do not support precompiled releases for other platforms, but you can always compile it yourself from source. See [Build from Source](../installation/#build-from-source). - -After installing Pilosa, you may have to add it to your `$PATH`. Check that you can run Pilosa from the command line: -``` request -pilosa --help -``` -``` response -Pilosa is a fast index to turbocharge your database. - -This binary contains Pilosa itself, as well as common -tools for administering pilosa, importing/exporting data, -backing up, and more. Complete documentation is available -at https://www.pilosa.com/docs/. - -Pilosa v1.4.0 -Build Time: 2019-09-23T14:33:07+0000 - -Usage: - pilosa [command] - -Available Commands: - check Do a consistency check on a pilosa data file. - config Print the current configuration. - export Export data from pilosa. - generate-config Print the default configuration. - help Help about any command - holder Load Pilosa. - import Bulk load data into pilosa. - inspect Get stats on a pilosa data file. - server Run Pilosa. - -Flags: - -c, --config string Configuration file to read from. - -h, --help help for pilosa - -Use "pilosa [command] --help" for more information about a command. -``` - -First, create a directory in which to put all of the files for this tutorial. Then switch to that directory: -``` -mkdir $HOME/pilosa-tls-tutorial && cd $_ -``` - -#### Creating the TLS Certificate and Gossip Key - -Securing a Pilosa cluster consists of securing the communication between nodes using TLS and Gossip encryption. - -The first step is acquiring the necessary TLS certificates. Operating your own public key infrastructure (PKI) is outside of the scope of this tutorial, but it is easy to get started with [certstrap](https://github.com/square/certstrap) for testing/development purposes. For production, you can use OpenSSL or any other software that provides PKI using X.509 certificates, including [Hashicorp Vault](https://learn.hashicorp.com/vault/secrets-management/sm-pki-engine). It is not recommended to use certstrap in production. - -First, create a certificate authority (CA): - -``` -$ certstrap init --common-name ca -Created out/ca.key -Created out/ca.crt -Created out/ca.crl -``` - -The command above creates three files in the `out/` directory: - -* `ca.key` is the CA private key file which must be kept as secret. -* `ca.crt` is the CA TLS certificate. -* `ca.crl` is the Certificate Revocation List (CRL). - -Next, create and sign a wildcard certificate for pilosa: - -``` -$ certstrap request-cert --cn "*.pilosa.local" -Created out/*.pilosa.local.key -Created out/*.pilosa.local.csr - -$ certstrap sign "*.pilosa.local" --CA ca -Created out/*.pilosa.local.crt from out/*.pilosa.local.csr signed by out/ca.key -``` - -The commands above create three files in the `out/` directory: - -* `*.pilosa.local.key` is the private key file which must be kept as secret. -* `*.pilosa.local.csr` is the certificate signing request (CSR). -* `*.pilosa.local.crt` is the signed TLS certificate. - -You can also create a separate client certificate signed by the same CA to test mutual TLS using curl: - -``` -$ certstrap request-cert --cn "curl" -Created out/curl.key -Created out/curl.csr - -$ certstrap sign "curl" --CA ca -Created out/curl.crt from out/curl.csr signed by out/ca.key -``` - -Having created the TLS certificates, we can now create the gossip encryption key. The gossip encryption key file must be exactly 16, 24, or 32 bytes to select one of AES-128, AES-192, or AES-256 encryption. Reading random bytes from cryptographically secure `/dev/random` serves our purpose very well: -``` -head -c 32 /dev/random > pilosa.local.gossip32 -``` - -We now have a file called `pilosa.local.gossip32` in the current directory which contains 32 random bytes. - -#### Creating the Configuration Files - -Pilosa supports passing configuration items using command line options, environment variables, or a configuration file. For this tutorial, we will use three configuration files; one configuration file for each of our three nodes. - -One of the nodes in the cluster must be chosen as the *coordinator*. We choose the first node as the coordinator in this tutorial. The coordinator is only important during cluster resizing operations, and otherwise acts like any other node in the cluster. In the future, the coordinator will be chosen transparently by distributed consensus, and this option will be deprecated. - -Create `node1.config.toml` in the project directory and paste the following in it: - -```toml -# node1.config.toml - -data-dir = "node1_data" -bind = "https://01.pilosa.local:10501" - -[cluster] -coordinator = true - -[tls] -ca-certificate = "out/ca.crt" -certificate = "out/*.pilosa.local.crt" -key = "out/*.pilosa.local.key" -enable-client-verification = true - -[gossip] -seeds = ["01.pilosa.local:15000"] -port = 15000 -key = "pilosa.local.gossip32" -``` - -Create `node2.config.toml` in the project directory and paste the following in it: - -```toml -# node2.config.toml - -data-dir = "node2_data" -bind = "https://02.pilosa.local:10502" - -[tls] -ca-certificate = "out/ca.crt" -certificate = "out/*.pilosa.local.crt" -key = "out/*.pilosa.local.key" -enable-client-verification = true - -[gossip] -seeds = ["01.pilosa.local:15000"] -port = 16000 -key = "pilosa.local.gossip32" -``` - -Create `node3.config.toml` in the project directory and paste the following in it: - -```toml -# node3.config.toml - -data-dir = "node3_data" -bind = "https://03.pilosa.local:10503" - -[tls] -ca-certificate = "out/ca.crt" -certificate = "out/*.pilosa.local.crt" -key = "out/*.pilosa.local.key" -enable-client-verification = true - -[gossip] -seeds = ["01.pilosa.local:15000"] -port = 17000 -key = "pilosa.local.gossip32" -``` - -Here is some explanation of the configuration items: - -* `data-dir` points to the directory where the Pilosa server writes its data. If it doesn't exist, the server will create it. -* `bind` is the address to which the server listens for incoming requests. The address is composed of three parts: scheme, host, and port. The default scheme is `http` so we explicitly specify `https` to use the HTTPS protocol for communication between nodes. -* `[cluster]` section contains the settings for a cluster. We set `coordinator = true` for only the first node to choose that as the coordinator node. See [Cluster Configuration](../configuration/#cluster-coordinator) for other settings. -* `[tls]` section contains the TLS settings, including the path to the TLS certificate and the corresponding key. The `ca-certificate` setting is optional and will default to your system CAs. You may also disable server-to-server verification by setting `skip-verify` to `true`, which we don't recommend for production. -* `[gossip]` section contains settings for the gossip protocol. `seeds` contains the list of nodes from which to seed cluster membership. There must be at least one gossip seed. The `port` setting is the gossip listen address for the node. If all nodes of the cluster are running on the same computer, the gossip listen address should be different for each node. Otherwise, it can be set to the same value. Finally, the `key` points to the gossip encryption key we created earlier. - -#### Final Touches Before Running the Cluster - -Before running the cluster, let's make sure that `01.pilosa.local`, `02.pilosa.local` and `03.pilosa.local` resolve to an IP address. If you are running the cluster on your computer, it is adequate to add them to your `/etc/hosts`. Below is one of the many ways of doing that (mind the `>>`): -``` -sudo sh -c 'printf "\n127.0.0.1 01.pilosa.local 02.pilosa.local 03.pilosa.local\n" >> /etc/hosts' -``` - -Ensure we can access the hosts in the cluster: -``` -ping -c 1 01.pilosa.local -ping -c 1 02.pilosa.local -ping -c 1 03.pilosa.local -``` - -If any of the commands above return `ping: unknown host`, make sure your `/etc/hosts` contains the failed hostname. - -#### Running the Cluster - -Let's open three terminal windows and run each node in its own window. This will enable us to better observe what's happening on each node. - -Switch to the first terminal window, change to the project directory and start the first node: -``` -cd $HOME/pilosa-tls-tutorial -pilosa server -c node1.config.toml -``` - -Switch to the second terminal window, change to the project directory and start the second node: -``` -cd $HOME/pilosa-tls-tutorial -pilosa server -c node2.config.toml -``` - -Switch to the third terminal window, change to the project directory and start the third node: -``` -cd $HOME/pilosa-tls-tutorial -pilosa server -c node3.config.toml -``` - -Let's ensure that all three Pilosa servers are running and they are connected: -``` request -curl --cacert out/ca.crt --cert out/curl.crt --key out/curl.key \ - https://01.pilosa.local:10501/status -``` -``` response -{"state":"NORMAL","nodes":[{"id":"98ebd177-c082-4c54-8d48-7e7c75857b52","uri":{"scheme":"https","host":"02.pilosa.local","port":10502},"isCoordinator":false},{"id":"a33dc0d6-c35f-4559-984a-e582bf032a21","uri":{"scheme":"https","host":"03.pilosa.local","port":10503},"isCoordinator":false},{"id":"e24ac014-ee2f-4cb0-b565-74df6c551f0a","uri":{"scheme":"https","host":"01.pilosa.local","port":10501},"isCoordinator":true}]} -``` - -The `-k` flag is used to tell curl that it shouldn't bother checking the certificate the server provides, and the `--ipv4` flag avoids an issue on MacOS where the curl request takes a long time if the address resolves to `127.0.0.1`. You can leave it out on Linux and WSL. - -If everything is set up correctly, the cluster state should be `NORMAL`. - -#### Running Queries - -Having confirmed that our cluster is running normally, let's perform a few queries. First, we need to create an index and a field: -``` request -curl --cacert out/ca.crt --cert out/curl.crt --key out/curl.key \ - https://01.pilosa.local:10501/index/sample-index \ - -X POST -``` -``` response -{"success":true} -``` - -This will create index `sample-index` with default options. Let's create the field now: -``` request -curl --cacert out/ca.crt --cert out/curl.crt --key out/curl.key \ - https://01.pilosa.local:10501/index/sample-index/field/sample-field \ - -X POST -``` -``` response -{"success":true} -``` - -We just created field `sample-field` with default options. - -Let's run a `Set` query: -``` request -curl --cacert out/ca.crt --cert out/curl.crt --key out/curl.key \ - https://01.pilosa.local:10501/index/sample-index/query \ - -X POST \ - -d 'Set(100, sample-field=1)' -``` -``` response -{"results":[true]} -``` - -Confirm that the value was indeed set: -``` request -curl --cacert out/ca.crt --cert out/curl.crt --key out/curl.key \ - https://01.pilosa.local:10501/index/sample-index/query \ - -X POST \ - -d 'Row(sample-field=1)' -``` -``` response -{"results":[{"attrs":{},"columns":[100]}]} -``` - -The same response should be returned when querying other nodes in the cluster: -``` request -curl --cacert out/ca.crt --cert out/curl.crt --key out/curl.key \ - https://02.pilosa.local:10502/index/sample-index/query \ - -X POST \ - -d 'Row(sample-field=1)' -``` -``` response -{"results":[{"attrs":{},"columns":[100]}]} -``` - -#### What's Next? - -Check out our [Administration Guide](https://www.pilosa.com/docs/latest/administration/) to learn more about making the most of your Pilosa cluster and [Configuration Documentation](https://www.pilosa.com/docs/latest/configuration/) to see the available options to configure Pilosa. - -### Setting Up a Docker Cluster - -In this tutorial, we will be setting up a 2-node Pilosa cluster using Docker containers. - -#### Running a Docker Cluster on a Single Server - -The instructions below require Docker 1.13 or better. - -Let's first be sure that the Pilosa image is up to date: -``` -docker pull pilosa/pilosa:latest -``` - -Then, create a virtual network to attach our containers. We are going to name our network `pilosanet`: - -``` -docker network create pilosanet -``` - -Let's run the first Pilosa node and attach it to that virtual network. We set the first node as the cluster coordinator and use its address as the gossip seed. And also set the server address to `pilosa1`: -``` -docker run -it --rm --name pilosa1 -p 10101:10101 --network=pilosanet pilosa/pilosa:latest server --bind pilosa1 --cluster.coordinator=true --gossip.seeds=pilosa1:14000 -``` - -Let's run the second Pilosa node and attach it to the virtual network as well. Note that we set the address of the gossip seed to the address of the first node: -``` -docker run -it --rm --name pilosa2 -p 10102:10101 --network=pilosanet pilosa/pilosa:latest server --bind pilosa2 --gossip.seeds=pilosa1:14000 -``` - -Let's test that the nodes in the cluster connected with each other: -``` request -curl localhost:10101/status -``` -``` response -{"state":"NORMAL","nodes":[{"id":"2e8332d0-1fee-44dd-a359-e0d6ecbcefc1","uri":{"scheme":"http","host":"pilosa1","port":10101},"isCoordinator":true},{"id":"8c0dbcdc-9503-4265-8ad2-ba85a4bb10fa","uri":{"scheme":"http","host":"pilosa2","port":10101},"isCoordinator":false}],"localID":"2e8332d0-1fee-44dd-a359-e0d6ecbcefc1"} -``` - -And similarly for the second node: -``` request -curl localhost:10102/status -``` -``` response -{"state":"NORMAL","nodes":[{"id":"2e8332d0-1fee-44dd-a359-e0d6ecbcefc1","uri":{"scheme":"http","host":"pilosa1","port":10101},"isCoordinator":true},{"id":"8c0dbcdc-9503-4265-8ad2-ba85a4bb10fa","uri":{"scheme":"http","host":"pilosa2","port":10101},"isCoordinator":false}],"localID":"2e8332d0-1fee-44dd-a359-e0d6ecbcefc1"} -``` -The corresponding [Docker Compose](https://docs.docker.com/compose/) file is below: - -```yaml -version: '2' -services: - pilosa1: - image: pilosa/pilosa:latest - ports: - - "10101:10101" - environment: - - PILOSA_CLUSTER_COORDINATOR=true - - PILOSA_GOSSIP_SEEDS=pilosa1:14000 - networks: - - pilosanet - entrypoint: - - /pilosa - - server - - --bind - - "pilosa1:10101" - pilosa2: - image: pilosa/pilosa:latest - ports: - - "10102:10101" - environment: - - PILOSA_GOSSIP_SEEDS=pilosa1:14000 - networks: - - pilosanet - entrypoint: - - /pilosa - - server - - --bind - - "pilosa2:10101" -networks: - pilosanet: -``` - -#### Running a Docker Swarm - -It is very easy to run a Pilosa Cluster on different servers using [Docker Swarm mode](https://docs.docker.com/engine/swarm/). All we have to do is create an overlay network instead of a bridge network. - -The instructions in this section require Docker 17.06 or newer. Although it is possible to run a Docker swarm on MacOS or Windows, it is easiest to run it on Linux. The following instructions assume you are running on Linux. - -We are going to use two servers: the manager node runs in the first server and a worker node in the second server. - -Docker nodes require some ports to be accesible from the outside. Before proceeding, make sure the following ports are open on all nodes: TCP/2377, TCP/7946, UDP/7946, UDP/4789. - -Let's initialize the swarm first. Run the following on the manager: -``` -docker swarm init --advertise-addr=IP-ADDRESS -``` - -Virtual machines running on the cloud usually have at least two network interfaces: the external interface and the internal interface. Use the IP of the external interface. - -The output of the command above should be similar to: -``` -To add a manager to this swarm, run the following command: - - docker swarm join --token SOME-TOKEN MANAGER-IP-ADDRESS:2377 -``` - -Let's make the worker node join the manager. Copy/paste the command above in a shell on the worker, replacing the token and IP address with the correct values. You may neeed to add `--advertise-addr=WORKER-EXTERNAL-IP-ADDRESS` parameter if the worker has more than one network interface: -``` -docker swarm join --token SOME-TOKEN MANAGER-IP-ADDRESS:2377 -``` - -Run the following on the manager to check that the worker joined to the swarm: -``` -docker node ls -``` - -Which should output: - -ID|HOSTNAME|STATUS|AVAILABILITY|MANAGER STATUS|ENGINE VERSION ----|--------|------|------------|--------------|------------- -MANAGER-ID *|swarm1|Ready|Active|Leader|18.05.0-ce| -WORKER-ID|swarm2|Ready|Active||18.05.0-ce| - -If you have created the `pilosanet` network before, delete it before carrying on, otherwise skip to the next step: -``` -docker network rm pilosanet -``` - -Let's create the `pilosanet` network, but with `overlay` type this time. We should also make this network attachable in order to be able to attach containers to it. Run the following on the manager: -``` -docker network create -d overlay pilosanet --attachable -``` - -We can now create the Pilosa containers. Let's start the coordinator node first. Run the following on one of the servers: -``` -docker run -it --rm --name pilosa1 --network=pilosanet pilosa/pilosa:latest server --bind pilosa1 --cluster.coordinator=true --gossip.seeds=pilosa1:14000 -``` - -And the following on the other server: -``` -docker run -it --rm --name pilosa2 --network=pilosanet pilosa/pilosa:latest server --bind pilosa2 --gossip.seeds=pilosa1:14000 -``` - -These were the same commands we used in the previous section except the port mapping! Let's run another container on the same virtual network to read the status from the coordinator: -``` request -docker run -it --rm --network=pilosanet --name shell alpine wget -q -O- pilosa1:10101/status -``` -``` response -{"state":"NORMAL","nodes":[{"id":"3e3b0abd-1945-441a-a01f-5a28272972f5","uri":{"scheme":"http","host":"pilosa1","port":10101},"isCoordinator":true},{"id":"71ed27cc-9443-4f41-88fb-1c22f92bf695","uri":{"scheme":"http","host":"pilosa2","port":10101},"isCoordinator":false}],"localID":"3e3b0abd-1945-441a-a01f-5a28272972f5"} -``` - -You can add additional worker nodes to both the swarm and the Pilosa cluster using the steps above. - -#### What's Next? - -Check out our [Administration Guide](https://www.pilosa.com/docs/latest/administration/) to learn more about making the most of your Pilosa cluster and [Configuration Documentation](https://www.pilosa.com/docs/latest/configuration/) to see the available options to configure Pilosa. - -Refer to the [Docker documentation](https://docs.docker.com) to see your options about running Docker containers. The [Networking with overlay networks](https://docs.docker.com/network/network-tutorial-overlay/) is a detailed overview of the Docket swarm mode and overlay networks. - - -### Using Integer Field Values - -#### Introduction - -Pilosa can store integer values associated to the columns in an index, and those values are used to support `Row`, `Min`, `Max`, and `Sum` queries. In this tutorial we will show how to set up integer fields, populate those fields with data, and query the fields. The example index we're going to create will represent fictional patients at a medical facility and various bits of information about those patients. - -First, create an index called `patients`: -``` request -curl localhost:10101/index/patients \ - -X POST -``` -``` response -{"success":true} -``` - -In addition to storing rows of bits, a field can also store integer values. The next steps creates three fields (`age`, `weight`, `tcells`) in the `patients` index. -``` request -curl localhost:10101/index/patients/field/age \ - -X POST \ - -d '{"options":{"type": "int", "min": 0, "max": 120}}' -``` -``` response -{"success":true} -``` - -``` request -curl localhost:10101/index/patients/field/weight \ - -X POST \ - -d '{"options":{"type": "int", "min": 0, "max": 500}}' -``` -``` response -{"success":true} -``` - -``` request -curl localhost:10101/index/patients/field/tcells \ - -X POST \ - -d '{"options":{"type": "int", "min": 0, "max": 2000}}' -``` -``` response -{"success":true} -``` - -Next, let's populate our fields with data. There are two ways to get data into fields: use the `Set()` PQL function to set fields individually, or use the `pilosa import` command to import many values at once. First, let's set some field data using PQL. - -The following queries set the age, weight, and t-cell count for the patient with ID `1` in our system: -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Set(1, age=34)' -``` -``` response -{"results":[true]} -``` - -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Set(1, weight=128)' -``` -``` response -{"results":[true]} -``` - -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Set(1, tcells=1145)' -``` -``` response -{"results":[true]} -``` - -In the case where we need to load a lot of data at once, we can use the `pilosa import` command. This method lets us import data into Pilosa from a CSV file. - -Assuming we have a file called `ages.csv` that is structured like this: -``` -1,34 -2,57 -3,19 -4,40 -5,32 -6,71 -7,28 -8,33 -9,63 -``` -where the first column of the CSV represents the patient `ID` and the second column represents the patient's `age`, then we can import the data into our `age` field by running this command: -``` -pilosa import -i patients --field age ages.csv -``` - -Now that we have some data in our index, let's run a few queries to demonstrate how to use that data. - -In order to find all patients over the age of 40, then simply run a `Row` query against the `age` field. -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Row(age > 40)' -``` -``` response -{"results":[{"attrs":{},"columns":[2,6,9]}]} -``` - -You can find a list of supported range operators in the [Row (BSI) Query](../query-language/#row-bsi) documentation. - -To find the average age of all patients, run a `Sum` query: -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Sum(field="age")' -``` -``` response -{"results":[{"value":377,"count":9}]} -``` -The results you get from the `Sum` query contain the sum of all values as well as the `count` of columns with a value. To get the average you can just divide `value` by `count`. - -You can also provide a filter to the `Sum()` function to find the average age of all patients over 40. -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Sum(Row(age > 40), field="age")' -``` -``` response -{"results":[{"value":191,"count":3}]} -``` -Notice in this case that the count is only `3` because of the `age > 40` filter applied to the query. - -To find the minimum age of all patients, run a `Min` query: -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Min(field="age")' -``` -``` response -{"results":[{"value":19,"count":1}]} -``` -The results you get from the `Min` query contain the minimum `value` of all values as well as the `count` of columns with that value. - -You can also provide a filter to the `Min()` function to find the minimum age of all patients over 40. -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Min(Row(age > 40), field="age")' -``` -``` response -{"results":[{"value":57,"count":1}]} -``` - -To find the maximum age of all patients, run a `Max` query: -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Max(field="age")' -``` -``` response -{"results":[{"value":71,"count":1}]} -``` -The results you get from the `Max` query contain the maximum `value` of all values as well as the `count` of columns with that value. - -You can also provide a filter to the `Max()` function to find the maximum age of all patients under 40. -``` request -curl localhost:10101/index/patients/query \ - -X POST \ - -d 'Max(Row(age < 40), field="age")' -``` -``` response -{"results":[{"value":34,"count":1}]} -``` - -### Storing Row and Column Attributes - -#### Introduction - -Pilosa can store arbitrary values associated to any row or column. In Pilosa, these are referred to as `attributes`, and they can be of type `string`, `integer`, `boolean`, or `float`. In this tutorial we will store some attribute data and then run some queries that return that data. - -First, create an index called `books` to use for this tutorial: -``` request -curl localhost:10101/index/books \ - -X POST -``` -``` response -{"success":true} -``` - -Next, create a field in the `books` index called `members` which will represent library members who have read books. -``` request -curl localhost:10101/index/books/field/members \ - -X POST \ - -d '{}' -``` -``` response -{"success":true} -``` - -Now, let's add some books to our index. -``` request -curl localhost:10101/index/books/query \ - -X POST \ - -d 'SetColumnAttrs(1, name="To Kill a Mockingbird", year=1960) - SetColumnAttrs(2, name="No Name in the Street", year=1972) - SetColumnAttrs(3, name="The Tipping Point", year=2000) - SetColumnAttrs(4, name="Out Stealing Horses", year=2003) - SetColumnAttrs(5, name="The Forever War", year=2008)' -``` -``` response -{"results":[null,null,null,null,null]} -``` - -And add some members. -``` request -curl localhost:10101/index/books/query \ - -X POST \ - -d 'SetRowAttrs(members, 10001, fullName="John Smith") - SetRowAttrs(members, 10002, fullName="Sue Perkins") - SetRowAttrs(members, 10003, fullName="Jennifer Hawks") - SetRowAttrs(members, 10004, fullName="Pedro Vazquez") - SetRowAttrs(members, 10005, fullName="Pat Washington")' -``` -``` response -{"results":[null,null,null,null,null]} -``` - -At this point we can query one of the `member` records by querying that row. -``` request -curl localhost:10101/index/books/query \ - -X POST \ - -d 'Row(members=10002)' -``` -``` response -{"results":[{"attrs":{"fullName":"Sue Perkins"},"columns":[]}]} -``` - -Now let's add some data to the matrix such that each pair represents a member who has read that book. -``` request -curl localhost:10101/index/books/query \ - -X POST \ - -d 'Set(3, members=10001) - Set(5, members=10001) - Set(1, members=10002) - Set(2, members=10002) - Set(4, members=10002) - Set(3, members=10003) - Set(4, members=10004) - Set(5, members=10004) - Set(1, members=10005) - Set(2, members=10005) - Set(3, members=10005) - Set(4, members=10005) - Set(5, members=10005)' -``` -``` response -{"results":[true,true,true,true,true,true,true,true,true,true,true,true,true]} -``` - -Now pull the record for `Sue Perkins` again. -``` request -curl localhost:10101/index/books/query \ - -X POST \ - -d 'Row(members=10002)' -``` -``` response -{"results":[{"attrs":{"fullName":"Sue Perkins"},"columns":[1,2,4]}]} -``` -Notice that the result set now contains a list of integers in the `columns` attribute. These integers match the column IDs of the books that Sue has read. - -In order to retrieve the attribute information that we stored for each book, we need to add a URL parameter `columnAttrs=true` to the query. -``` request -curl localhost:10101/index/books/query?columnAttrs=true \ - -X POST \ - -d 'Row(members=10002)' -``` -``` response -{ - "results":[{"attrs":{"fullName":"Sue Perkins"},"columns":[1,2,4]}], - "columnAttrs":[ - {"id":1,"attrs":{"name":"To Kill a Mockingbird","year":1960}}, - {"id":2,"attrs":{"name":"No Name in the Street","year":1972}}, - {"id":4,"attrs":{"name":"Out Stealing Horses","year":2003}} - ] -} -``` -The `book` attributes are included in the result set at the `columnAttrs` attribute. -
