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

             Summary: Give a option to ignore the timer that is larger than END_OF_GLOBAL_WINDOW
                 Key: BEAM-2487
                 URL: https://issues.apache.org/jira/browse/BEAM-2487
             Project: Beam
          Issue Type: Improvement
          Components: runner-flink
            Reporter: Jingsong Lee


Event time can not reach END_OF_GLOBAL_WINDOW in unbounded world. (Except for testing)
But Flink runner will set some timers when user set a StatefulPardo/GBK with GlobalWindow.
Flink maintains timers in PriorityQueue on the Java Heap. There is a bad performance when
the number of keys is very much.
