Roman Kondakov updated IGNITE-10794:
------------------------------------
Fix Version/s: 2.8
> MVCC: RemoveAll is broken on unstable topology
> ----------------------------------------------
>
> Key: IGNITE-10794
> URL: https://issues.apache.org/jira/browse/IGNITE-10794
> Project: Ignite
> Issue Type: Bug
> Components: mvcc
> Reporter: Andrew Mashenkov
> Assignee: Andrew Mashenkov
> Priority: Critical
> Labels: Hanging, mvcc_stabilization_stage_1, transaction
> Fix For: 2.8
>
>
> Enlist batch holds key and values in arrays structures. This implies that
> keys and vals arrays sizes should be equals.
> Also, we have an optimization and do not save 'null' vals for 'remove'
> operation.
> This invariant can become broken on removeAll operation for 2 entries
> belonging to partitions in different states (moving and owning). For the
> first one, it's 'mvcc history' will be added to 'vals' array, but nothing
> will be added for the second one.
> Reproducer IgniteCacheEntryProcessorNodeJoinTest.testEntryProcessorNodeLeave
