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

             Summary: Allow cancelation and reset of timers
                 Key: FLINK-9440
                 URL: https://issues.apache.org/jira/browse/FLINK-9440
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.4.2
            Reporter: Elias Levy


Currently the {{TimerService}} allows one to register timers, but it is not possible to delete a timer or to reset a timer to a new value.  If one wishes to reset a timer, one must also handle the previous inserted timer callbacks and ignore them.

I would be useful if the API allowed one to remove and reset timers.
