> 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.
