------------------------------------------

Completed windows (endWindow) are supposed to be flushed to WAL, irrespective of committed.

> The KafkaSinglePortExactlyOnceOutputOperator fails on recovery with the message: "Violates Exactly once. Not all the tuples received after operator reset."
> This is because of this check in endWindow():
> {code}
>    if (!partialWindowTuples.isEmpty() && windowId > windowDataManager.getLargestCompletedWindow()) {
>       throw new RuntimeException("Violates Exactly once. Not all the tuples received after operator reset.");
>     }
> {code}
