Reuven Lax created BEAM-12690:
---------------------------------
Summary: GroupIntoBatches does not properly maintain watermarks
Key: BEAM-12690
URL: https://issues.apache.org/jira/browse/BEAM-12690
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Reuven Lax
Since GIB buffers elements, the watermark should be held up to the minimum
event-time buffered. Timer.withOutputTimestamp is the correct way to do this in
Beam.
