* Implement Schemar.SetDatabaseOption(option, value string)
This replaces the temporary `SetDatabaseOptions()` method, which
replaced the entire DatabaseOptions struct, with `SetDatabaseOption`
which takes an option/value pair of strings to set.
* Add SetDatabaseOption to controller http handler and client
This commit also:
- renames some `writeLog` to `writelog`
- updates ApplyDirective to call resource.Unlock() on any resources
being removed from the local worker
* Add Database related methods to SchemaAPI interface
Currently all implementations of this interface are implemented with
"unimplemented" errors on those methods. Next will be to implement the
necessary methods.
* SQL: CREATE DATABASE and SHOW DATABASES
* SQL: DROP DATABASE
* SQL: Add UNITS option to CREATE DATABASE
* SQL: ALTER DATABASE
* User serverlessStorage.Remove[*]Resource instead of resource.Unlock()
* Add WITH keyword to CREATE/ALTER DATABASE
* fix some WITH logic
* linter fixes
* WITH on CREATE DATABASE is not required
* Support Drop Table in serverless (include Snapshotter, Writelogger)
* Finish Database methods
Things like:
- `Databases`
- `DatabaseByID`
- `DatabaseByName`
- `DropDatabase`
* Change Poller to use NodeService instead of its own map
Instead of the Poller maintaining its own map of Addresses to poll, this
commit changes the Poller to use the NodeService interface to get all
known nodes from the Controller.
The next commit needs to:
Next, the logic in the boltdb NodeService implementation was moved to
the boltdb Balancer implementation. That way, the Balancer can be the
source of truth for all things nodes/workers/jobs.
* Move NodeService from Controller to Balancer
This commit moves the implementation of the NodeService into the
Balancer, and aligns `Balancer.AddWorker` with `NodeService.CreateNode`
so that they stay in sync. (Same for `Balancer.RemoveWorker` and
`NodeService.DeleteNode`).
* fix import of private repo
* Fix go vet issues
* Fix bug in DeregisterNode
We need to remove the node from the NodeService even if it's not
assigned to a database. The logic had a bug in it.
This also adds some no-op implementations for SnapshotService and
WriteloggerService. If a directory was not configured for that, then the
computer node would panic on trying to read from the Snapshotter upon
receiving a Directive.
* queryer response content-type: json
* Add support for NULL to WriteloggerDir and SnapshotterDir configs
This commit changes the way WriteLoggerDir and SnapshotterDir are
handled.
If value is empty `""`, an error will be returned on computer startup.
If value is `"NULL"`, a no-op implementation of the service will be
used. This would be for a case that wanted to run serverless on-prem
with no durable storage.
Finally, any other value will be used as the directory to use.
Some things which aren't considered here and may result in unexpected
behavior:
- a value with spaces `" "`
- any "null" which is not "NULL"... like lowercase.
* Finish the DropTable test
* Change "disable service" value to case-insensitive "off"
This commit also removes an unnecessary sleep in the tests.
* Fix docker-compose variables for IDK test

* first cut at pre-sort command that works on ndjson
* finish pre_sort command for CSV and JSON and add test
* try fixing golangci-lint
* remove some dumb lint checks
* more linter disabling
* take .golangci.yml from previous repo
* go fmt (facepalm)
* remove ioutil to fix lint
* Database isolation: Balancer
Remove naive Balancer
remove debugging lines
Thread dax.Transaction through Controller
Change role to roleType
Swap out Balancer interface with new one
Standardize InvalidTransaction error
Add some interface comments
* Remove type.Worker; replace with type.Address
* Remove database validate from Queryer
This is already being handled in the `CreateTable()` method. Prior
to doing that validation, we were getting a panic, but that's no longer
the case.
* Remove dax.TableQualifier; replace with dax.QualifiedDatabaseID
* Update IDK test to create database
(cherry picked from commit d971cfc269)
* implement CREATE/ALTER/DROP VIEW
* fixed failing test
* another failing test
* fixed some broken serverless tests
(cherry picked from commit c620aae350)
* performance counters
* first cut of perf counters and system table fanout and a wire protocol
* significantly refactored prometheus support; removed statsd and exprvar
* removed node_id
* put dax subquery test back
* Change Translator.TranslateFieldIDs method to take a dax.TableKeyer
There are a bunch of other calls to the Translator interface methods
with currently take an `index string`, and those need to be converted to
dax.TableKeyer as well. But I need to review each call, because in at
least one place I noticed one being called with `result.Index` instead
of with the qtbl available. And I don't yet know how those could be
different.

* Fix PQL distinct in dax
When issuing a PQL Distinct() call (or any other call with a "index=" arg),
this commit will attempt to convert the value in the index arg with a
TableKeyer.
* Apply change to call.Children as well
* Add some PQL Distinct (join) test coverage
(cherry picked from commit 4e8fe488de)
* Fix "qualifer" misspellings

I took the liberty of renaming "LastUpdatedUser" to "UpdateBy" to align
with "UpdatedAt".
