---------------------------------------

             Summary: Incremental cleanup of local expired state with TTL discovered in full snapshot 
                 Key: FLINK-10132
                 URL: https://issues.apache.org/jira/browse/FLINK-10132
             Project: Flink
          Issue Type: Improvement
          Components: State Backends, Checkpointing
    Affects Versions: 1.7.0
            Reporter: Andrey Zagrebin
            Assignee: Andrey Zagrebin
             Fix For: 1.7.0


This issue suggests to extend approach from FLINK-9938 and add a queue between a snapshotting thread which discovers expired state during its full scan and main thread which accesses state and can incrementally pull the queue and clean up local state if still applicable.
