> 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.
