Yuan Mei updated FLINK-22678:
-----------------------------
Description:
To enable/config Changelog Statebackend, we need to set
1. "state.backend.changelog.enabled" and
2. choose the state backend to be delegated
These two configs can be set in both Job level or cluster level; Job level
configs override Cluster level's.
If no state backend is set, a default one (Mem) is set.
=====
There are totally four combinations under this set up/overrides. The other
three work fine except
"state.backend.changelog.enabled" in Job level, but state backend is chosen in
cluster level.
"state.backend.changelog.enabled" is lost.
