> 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.
