Ingo Bürk commented on FLINK-22737:
-----------------------------------
Thanks for your input [~jark]! I discussed this with [~twalthr] and we agree
that passing the event-time attribute as an argument solves a couple of
problems, so we'll go with that. However, we would still have NULL values for
the case where no watermark has yet been emitted. Or did you have something
else in mind for this?

> Project: Flink

> Components: Table SQL / API
> Reporter: David Anderson
> Assignee: Ingo Bürk
> Priority: Major
>
> With a built-in function returning the current watermark, one could operate
> on late events without resorting to using the DataStream API.
> Called with zero parameters, this function returns the current watermark for
> the current row – if there is an event time attribute. Otherwise, it returns
> NULL.
