The pb package was only referenced in cmd/influx/query.go, but in
dead code, since it uses the same machinery as the repl, which goes
through the HTTP endpoints, rather than the gRPC endpoints.
We reorganized the functions in flux to have the structure:
/functions
/inputs
/transformations
/outputs
this PR catches up platform to work with the new package layout.
As a separate refactoring issue, we should discuss:
from(bucket: ) should migrate from flux --> platform
to_http and to_kafka should migrate from platform --> flux
It creates a simple client that follows the QueryService interface and
uses the `influxql.Compiler` type to determine where the query should be
routed to and to return the query as a `flux.ResultIterator`.
This will be useful for replaying transpiler queries against influxdb
1.x servers to verify correctness.
This iterface is supposed to be something that both sessions and
authorizations can share so that other components can authorize requests
as they see fit.
The `-i` flag causes a problem when a cross compilation happens because
it attempts to build files in GOROOT which is located in a directory
that is not writable by the build user. This same problem exists for
when the `-tags` are changed like adding `-tags assets` in the `all`
build that runs on the master branch.
This removes `-i` because, in the latest go release, the `-i` flag
doesn't actually do anything useful since there is another build cache
that the results are placed in regardless of whether `-i` is used.
This fixes the build on master so that `make all` and `make nightly`
will function properly.
This updates the dependency manager to use go modules instead of dep so
that we can remove dep as a dependency and we can begin using and giving
feedback on modules within this project. It should simplify dependency
management and make it faster to run the builds too.
The big change is updating the various Makefiles to stop relying on the
vendor directory because it no longer exists. This change creates a
`tools.go` file with the revisions of the tools we use that are currently
in the `required` section of `Gopkg.toml`. We are currently in other
discussions to modify how we handle tool dependency management, but this
change does not change that.
The transpiler will normalize the `_time` column by dropping any
existing time column and then duplicating `_start` when the query is an
aggregate type.
This works for the selectors because they did not normalize their
`_time` column at all and, while the aggregates did normalize their
`_time` column, we have made the decision to remove that functionality
and have aggregates not set a `_time` column at all.
Instead of generating multiple cursors, a pivot is used to join fields
within the same series.
This should be easier than generating a new cursor for everything.
WIP: saving state reword
feat(query/influxql): implement query.ResultIterator directly on response
review(influxql): add ResponseIterator that implement query.ResultIterator
review(influxql): update code is response to review
The previous default was just to have no limit at all. This adds a
configuration option to the planner so a static value can be set for the
memory limit on each individual query.

The query statistics would only be read after the cancel call so we need
to wait for that before attempting to read the statistics rather than
attempting to read them immediately after the result is returned (before
it is read).
* Added default signature generators for Selector and Aggregate configs and update the functions that need them
* fix to percentile to collect the correct arguments for both aggregate and selector
The REPL's use of the interpreter was causing it to not get the builtins
defined in builtin scripts. For example the `top` function was missing.
This change fixes the issues by ensuring the builtins are only evaluated
once and that there is only one way to get the query Interpreter that is
guaranteed to have the proper builtins.
The logger is now threaded into the query controller, executor, and the
dispatcher so that we can log panics. They are logged at the info level
because the panics do not result in the system crashing and becoming
unusable.
Durations are changed to be a 3 vector to form a linear basis of
seconds, days, and months.
Interval comprehensions are introduced to be able to define complex
calendar intervals.
Specification is added around time zones.
The window function is update to default to not returning incomplete
windows.
The call to `setErr` would grab a lock that `Pop` used, but `setErr`
requires the controller run loop to be executing for it to work. If we
reverse the order of these calls, it should be fine.
When the controller moves to one of the finished states, it will finish
the parent span so that can be recorded. It presently will do this
multiple times when transitioning between different finished states.
This normally happens within the finishing states, but when compiling or
queueing fails it never enters those finished states and is instead
discarded. We need to signal that the query itself has finished in the
metrics.
This documents the responsibilities of what the Controller does and is
expected to do. It describes some behaviors that aren't implemented, but
acts as a guide for what the Controller should do as we continue
developing the query engine and improving the internal mechanics.
This commit provides a new join implementation that can join
tables with different group keys. It also implements a strategy
for evicting stale data from the join operation's cache when
it can be determined that a table will no longer be joined.
Currently early table eviction from the buffers of the join occurs
when the left-most group key column of both input streams are equal
and that column is part of the join key.
Moves idpe.QueryService into platform/query.ProxyQueryService
Splits the Request into ProxyRequest and Request.
Changes query.QueryService and query.AsyncQueryService to use a Request
type. This means that the Compiler interface is consumed by the service
to abstract out transpilation vs Flux compilation vs raw spec.
The transpiler handler is removed.
There are separate http handlers and service implementations for each of
the three query services.
Query logging types are moved into platform.
The ResultIterator now expects Cancel to always be called.
The fluxd binary exposes the query endpoint specified in the swagger
file.
For details, the user can always look at the spec, but a good getting
started guide that works is needed.
At the moment, this does not use the influx command. It does include
instructions for how to get started with docker since that is easiest to
setup and use.
