Resolution: Fixed
> Support merging WindowFn other than IntervalWindow on Flink Runner
> ------------------------------------------------------------------
>
> Key: BEAM-1772
> URL: https://issues.apache.org/jira/browse/BEAM-1772
> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Reporter: Ismaël Mejía
> Assignee: Jingsong Lee
> Fix For: First stable release
>
>
> Flink currently supports merging IntervalWindows, however if you have a WindowFn who extends IntervalWindow the execution breaks.
> I found this while executing a Pipeline in Flink's batch mode.
> This will involve probably changing the window merging logic in `FlinkMergingReduceFunction.mergeWindows()` and other similar parts to really use the merging logic of the `WindowFn`.
