[jira] [Created] (FLINK-23137) State ownership: disable discarding state of ChangelogStateBackendHandle on JM

Roman Khachatryan created FLINK-23137:
-----------------------------------------

             Summary: State ownership: disable discarding state of ChangelogStateBackendHandle on JM
                 Key: FLINK-23137
                 URL: https://issues.apache.org/jira/browse/FLINK-23137
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / State Backends
            Reporter: Roman Khachatryan
             Fix For: 1.14.0


TM should own changelog backend state to prevent re-uploading state on checkpoint abortion (or missing confirmation). A simpler solution to only own aborted state is less maintanable in the long run.

For that, on JM side, ChangelogStateBackendHandle shouldn't discard and nor register and yhared state.
For TM, ticket will follow.
