> The Flink Runner's {{ImpulseSourceFunction}} does not emit a final watermark,
> unless {{--shutdownSourcesOnFinalWatermark}} flag has been specified (the
> flag is used in tests to shutdown the pipeline after reading all data). Most
> pipelines will be long-running and thus do not specify the flag.
> Not sending out the final watermark causes GroupByKey to hold back the data
> of event time windows until the pipeline is shut down (the final watermark is
> always emitted on pipeline shutdown which is why using the above flag works).
