----------------------------------------
Assignee: Alexander Lapin
> Assert that it's not possible to deployWatches before
> metaStorageManager.start()
> --------------------------------------------------------------------------------
>
> Key: IGNITE-19606
> URL: https://issues.apache.org/jira/browse/IGNITE-19606
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexander Lapin
> Assignee: Alexander Lapin
> Priority: Major
> Labels: ignite-3
>
> h3. Motivation
> Occurred that in some tests deployWatches was called on not started
> metaStorageManager which leads to failures and unpredictable artifacts. In
> order to prevent such possibility it's required to add corresponding
> assertion in deployWatches.
> h3. Definition of Done
> Calling deployWatches on not started meta storage manager will result in an
> AssertionException.
> h3. Implementation Notes
> * I don't think that it's worth to prepare some general solution for all
> IgniteComponents that will prevent calling their methods before start, for
> now it's only about MetaStorage and deployWatches.
> * MetaStorageManager has two implementations MetaStorageManagerImpl and
> StandaloneMetaStorageManager, so we should have two tests for given assertion.
> * Assertion itself might be implemented though `metaStorageSvcFut.thenRun(()
> -> \{storage.startWatches(this::onRevisionApplied);});`
