Labels: Hanging transaction (was: Hanging mvcc_stabilization_stage_1 transaction)
> 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, transaction
> Fix For: 2.8

> Time Spent: 10m
> Remaining Estimate: 0h

> 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.
