> URL: https://issues.apache.org/jira/browse/IGNITE-9828
> Project: Ignite
> Issue Type: Task
> Components: mvcc
> Reporter: Roman Kondakov
> Assignee: Roman Kondakov

> Fix For: 2.7

>
> We need to implement failover procedure for CQ with MVCC caches. Thoughts:
> * CQ failover tests should be adopted for mvcc scenarios. See
> {{IgniteCacheQuerySelfTestSuite4}}
> * We need to ensure the correctness of CQ and partition counters consistency
> in cases when some of TX participants are in prepared state and others are
> marked as rollback only. It looks like it doesn't work properly now.
