> This is the same issue as for {{ContinousFileReaderOperator}} in
> https://issues.apache.org/jira/browse/FLINK-13376. {{AsyncWaitOperator}} will
> propagate {{endInput}} notification immediately, even if it has some records
> buffered.
> Side note, this also shows that the current {{BoundedOneInput#endInput}} API
> is easy to mishandle if an operator buffers some records internally. Maybe we
> could redesign this API somehow [~aljoscha] [~sunhaibotb]?
