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

             Summary: Add registerNextWatermarkCallback() to TimerService
                 Key: FLINK-5809
                 URL: https://issues.apache.org/jira/browse/FLINK-5809
             Project: Flink
          Issue Type: Bug
          Components: DataStream API
            Reporter: Aljoscha Krettek


This new method is similar to {{registerEventTimeTimer()}} but instead of specifying a certain time where the timer should fire this will simply fire whenever a new watermark arrives.

This is, for example, useful when you want to buffer elements for sorting by event time and always want to emit as soon as the operator receives a watermark.
