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

             Summary: WindowOperator registers a log of timers at StreamTask
                 Key: FLINK-3669
                 URL: https://issues.apache.org/jira/browse/FLINK-3669
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.0.1
            Reporter: Aljoscha Krettek
            Priority: Blocker


Right now, the WindowOperator registers a timer at the StreamTask for every processing-time timer that a Trigger registers. We should combine several registered trigger timers to only register one low-level timer (timer coalescing).
