> Currently when doing aggregation queries, we can output insert only results
> only when grouping by windows. But when users defined event time and also
> watermark, we can also support emit insert only results when grouping on
> event time. To be more precise, it should only require event time is one of
> the grouping keys. One can think of grouping by event time is kind of a
> special window, with both window start and window end equals to event time.
