* feat(task): add limit function for task concurrency
The new task executor handles limit's differently then the old executor
instead of front loading limits by creating a runner for every task that might run
the new executor has a large worker pool and queue. This allow's us to have a unlimited
concurrency per task and helps us avoid a back log of task's execution based on a
arbitrary execution limit. This add's the ability to add an optional task execution limit
so a user can still have the advantages of limiting concurrency.
We needed the coordinator to be able to execute manual runs and resume runs.
These two functions have been added, but we also needed to allow for the executor to be
mocked out. To do that we needed to return a Promise interface instead of an actual
struct. Both these changes are to facilitate coordinator work and testing.
I chose to add a execute function that allow's the task executor to match expectation from
the scheduler but I left in the existing executor method that return's promises. This is
because I like to be able to have the accountablilty and visiblity inside what's happening
with each execution even though the promise isn't required for the scheduler. This function signature
will be used by the coordinator and potentially other's that want to ensure a 'execution' is completed.
Implementations of the backend.Executor produce errors limited to
querying the KV store. The remainder of the errors will be processed
in the implementation of a `RunPromise`.
Fixes#15161
When a task is told to execute it can be enqueued waiting for a worker.
This statistic will be superior to the existing delta based on scheduled for,
the current system can be effected by a user having slow queries or a long "delay" on the task.
This new way of measuring the same thing should allow us to accuratly measure when it is the task system's fault.
* feat(task): impersonate user on task execution
Passing tokens to tasks is cumbersome and we needed a way to more easily create tasks. With this change we no longer need a token on task create. We take the user that created the task and pass that in as the "owner". As far as the task is concerned the owner is the source of permissions.
This is done by adding an additional field on task create that is OwnerID. We will no longer respect the token passed in and it will be deprecated soon.
Things to do still:
Task updates need to allow for owners to be set.
* Report errors found when iterating over flux query in task
* Add failing test for tasks executor result iterator exhaust failure
* Ensure errors exhausting tasks query result iterator are surfaced as task failure
* Update CHANGELOG with task result iteration error surfacing fix
This replaces usages of the spec compiler with the ast compiler and it
removes the error message referencing the spec compiler as an available
input.
It does not remove any of the code using the spec compiler that is
involved for proxying requests and it does not remove it from the API.
The synchronous executor was missing a call to ResultIterator.Release.
The asynchronous executor wasn't even calling Query.Statistics.
Also add a test that the scheduler records the statistics to the run
log, and that the statistics are visible from the launcher test. The
launcher test is the most likely place to catch if something goes wrong
in the full stack.
Immediately before the executor calls out to the query service, the
executor loads the authorizer associated with the task, and associates
that authorizer with the context used to execute the query.
Accept token when creating or updating a task, but only report back the
authorization ID.
This means the executor and the platform adapter are now both aware of
an Authorization Service.
I did this with a dumb editor macro, so some comments changed too.
Also rename root package from platform to influxdb.
In interest of minimizing risk, anyone importing the root package has
now aliased it to "platform" so that no changes beyond imports were
necessary in those files.
Lastly, replace the old platform module to local path /dev/null so that
nobody can accidentally reintroduce a platform dependency while
migrating platform code to influxdb.
This is to ensure that Scheduler.Stop blocks until outstanding task runs
finish. There were enterprise tests failing because outstanding runs of
a task were calling (*testing.T).Log after the test finished.
- Brought over enterprise's QueryLogReader, with small adjustments
- Time filters are for the run's ScheduledFor field, per spec
- Adjusted run log timestamps for consistent formatting:
- ScheduledFor is RFC3339 because it's a whole-second timestamp
- StartedAt, FinishedAt use RFC3339Nano for high precision
- Several test adjustments to use relative time, for easier integration
with storage retention
We are moving the necessary code for 2.0 from the influxdb 1.X
repository to the platform 2.0 repository. The logger is an unnecessary
dependency on the old influxdb that is making life more complicated.
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.
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.
