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.
More specifically, introduce a `scheduleAfter` argument to
Store.CreateTask. The previous behavior was leaving a new task's meta
LatestComplete value set to zero, which meant that the first run of a
schedule would start from 1970. Now, it's set to time.Now unless
otherwise specified.
Updates #595.
We were previously doing `r.logger = r.logger.With(...)`, which ended up
duplicating the provided field in the log output. Now ensure that we
only set the run_id once in a logger.
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.
