Epic Link: IGNITE-19743 (was: IGNITE-19577)
> API and tests for causality data nodes in DistributionZoneManager
> -----------------------------------------------------------------
>
> Key: IGNITE-19602
> URL: https://issues.apache.org/jira/browse/IGNITE-19602
> Project: Ignite
> Issue Type: Bug
> Reporter: Sergey Uttsel
> Assignee: Sergey Uttsel
> Priority: Major
> Labels: ignite-3
> Time Spent: 10m
> Remaining Estimate: 0h
>
> h3. *Motivation*
> In https://issues.apache.org/jira/browse/IGNITE-19506 we will create
> implementation for getting data nodes from zone manager with causality token.
> In this ticket we need to create API, test plan and implement tests with test
> infrastructure.
> h3. *Definition of Done*
> API and tests for causality data nodes in DistributionZoneManager are
> implemented.
>
> *Test plan*
> *Test1* (Not implemented because it assumes that we will use versioned value.
> For now we are not going to use a versioned value)
> Prerequisite:
> 1. zonesByRevision contains [revision=5, zoneId==1 -> [nodeA, nodeB]]
> Test steps:
> 1. Get versionedDataNodes future with zoneId=1, revision 6.
> 2. Check this future is not completed.
> 3. Create a metastorage event with revision==6 which is not related to a
> logical topology changing.
> 4. Check that the future is completed with [nodeA, nodeB].
> 5. Get versionedDataNodes future with zoneId=1, revision 6 another time.
> 6. Check that the future is completed.
> Check the same test but with a configuration event.
> Check this test case for a zone with immediate and not immediate timers,
> default and custom zones.
> *Test2* topologyLeapUpdate

> 6. assertThat(fut1, willSucceedFast())
> 7. assertThat(fut2, willSucceedFast())
> 8. Check that fut1 is completed with [nodeA, nodeC]
> 9. Check that fut2 is completed with [nodeA, nodeB].
> 10. Wait when data nodes for zone2 is updated in the metastorage (with
> revision x).
