Yuan Mei updated FLINK-29082:
-----------------------------
Description:
Since ChangelogRegistry is not persisted, registration information is lost
after failover.
It may lead to changelog leftovers.
We can use a similar way proposed in FLINK-24852 for this.
Or other ways like TM-owned/managed files.
