> This would allow to specify whether windows should be discarded after the trigger fires
or kept in the operator if late elements arrive.
> When keeping elements, the user would also have to specify an allowed lateness time after
which the window contents are discarded without emitting any further window evaluation result.
> If elements arrive after the allowed lateness they would trigger the window immediately
with only the one single element.
