hi, [~fhueske] RetractionRules will make sure that
{{DataStreamGroupWindowAggregate}} and {{DataStreamOverAggregate}} can not
receive purely update messages(updates without retraction). If they did, IMO,
we may need to fix the RetractionRules, not the other way around.
As for the {{DataStreamWindowJoin}}, we need to set needsUpdatesAsRetraction to
true considering that it can not handle purely update messages and check that
the input does not have retraction messages. : )
