Is there any updates on this question ? I would be keen to know either way and what is expected.

Hi @bloomfm100 sorry for the delay in responding. You're correct, if there are no events coming into the stream pipeline nothing can be emitted indicating that there were zero events. The pipeline only operates against incoming data, the window will only be set once the first event arrives.
There is no easy way to force the window to always operate if no events are arriving. Perhaps you can consider a timer trigger?
