Summary: MVCC: Continuous query failover.
Key: IGNITE-9828
URL: https://issues.apache.org/jira/browse/IGNITE-9828
Project: Ignite
Issue Type: Task
Components: mvcc
Reporter: Roman Kondakov
We need to implement failover procedure for CQ with MVCC caches. Thoughts:
* Mvcc updates should be cached in the persistent off-heap data structures
instead of heap.
* 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.
