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

             Summary: Potential lack of synchronization w.r.t. newSstFiles in RocksDBKeyedStateBackend#releaseResources()
                 Key: FLINK-6467
                 URL: https://issues.apache.org/jira/browse/FLINK-6467
             Project: Flink
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


{code}
      if (canceled) {
        List<StateObject> statesToDiscard = new ArrayList<>();

        statesToDiscard.add(metaStateHandle);
        statesToDiscard.addAll(miscFiles.values());
        statesToDiscard.addAll(newSstFiles.values());
{code}
It seems access to newSstFiles should be protected by stateBackend.asyncSnapshotLock
