Date Tue, 15 Nov 2016 23:22:58 GMT
Sam Whittle created BEAM-986:
--------------------------------

             Summary: ReduceFnRunner doesn't batch prefetching pane firings
                 Key: BEAM-986
                 URL: https://issues.apache.org/jira/browse/BEAM-986
             Project: Beam
          Issue Type: Bug
          Components: runner-core
            Reporter: Sam Whittle
            Assignee: Sam Whittle


Specifically
- in ProcessElements, if there are multiple windows to consider each is processed sequentially
with sequential state fetches instead of a bulk prefetch
- onTimer method doesn't evaluate multiple timers at a time meaning that if multiple timers
are fired at once each is processed sequentially without batched prefetching
