---------------------------------------
Summary: Make Closing Behavior of Window Operators Configurable
Key: FLINK-3178
URL: https://issues.apache.org/jira/browse/FLINK-3178
Project: Flink
Issue Type: Improvement
Components: Streaming
Reporter: Aljoscha Krettek
Right now, all window operators emit (incomplete) in-flight windows when they
are closing down. This happens for two reasons:
1. sources emit a final Long.MAX_VALUE watermark to flush out windows when they
close.
2. window operators emit in-flight windows in their close() method
For some users this might not be the desired behavior so we should either
change it or make it configurable.
