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

             Summary: FlinkRunner: pipeline might get stuck due to timer watermark hold not being released
                 Key: BEAM-10691
                 URL: https://issues.apache.org/jira/browse/BEAM-10691
             Project: Beam
          Issue Type: Bug
          Components: runner-flink
    Affects Versions: 2.23.0, 2.24.0
            Reporter: Jan Lukavský
            Assignee: Jan Lukavský


Pipeline might stop progressing watermark in certain cases due to timer output timestamp not being released from FlinkTimerInternals#outputTimestampQueue. The pipeline has to be restarted from checkpoint to reload the cache and free watermark hold.
