>
> We should add the possibility for WindowAssigners to merge windows. This will
> enable Session windowing support, similar to how Google Cloud Dataflow
> supports.
> For session windows, each element would initially be assigned to its own
> window. When triggering we check the windows and see if any can be merged.
> This way, elements with overlapping session windows merge into one session.
