A `StatsClient` for `expvar` is added so we can track Stats through
the `/debug/vars` endpoint. Tags are nested inside maps so that we
can see stats for db, frame & slice.
Also added a `MultiStatsClient` for chaining multiple `StatsClient`
implementations together (e.g. `expvar` and DataDog).
This commit adds a simple benchmarking utility to the `pilosactl`
binary. It currently only supports individual `SetBit()` commands
but it's a good start towards making a generic benchmarking
framework at the integration level.
The subcommands and usage/help messages were also cleaned up to
output correctly.
This commit adds a new HTTP handler to return a list of all databases
and frames in the index:
GET /schema
This returns JSON in the following format:
{
"dbs":[
{
"name":"d0",
"frames":[
{"name":"f0"},
{"name":"f1"}
]
}
]
}
Fixes#61
This commit refactors the profile and bitmap attribute stores so
that they share the same code. There is a new `AttrStore` which
associates key/value pairs with a `uint64` identifier.
The previous JSON encoding has been fixed to use protobufs which
fixes encoding issues for int64.
This commit adds the ability to set string, integer, and boolean
values on bitmaps and profiles within Pilosa. Bitmap attributes
are automatically returned when making a `Bitmap()` call. Profile
attributes must be requested by setting `profile=true` in the
URL.
The function names have also been renamed to initial caps so that
the PQL query language can support math operations in the future.
