Xingcan Cui commented on FLINK-7446:
------------------------------------
Thanks for the response, [~fhueske]. From my perspective, I prefer the later
option (create new interfaces/operators...). Maybe we can provide one or more
default watermark generators. Users can directly set them by providing some
parameters (e.g., the watermark interval and the expected delay to the latest
rowtime). Moreover, if the provided watermark generators can not meet the
requirements, users can implement their own ones. What do you think, [~jark]?

> Currently {{DefinedRowtimeAttribute}} can define an appended rowtime field
> for a {{TableSource}}. But it would be helpful if we can support to define an
> existing field as the rowtime field. Just like registering a DataStream, the
> rowtime field can be appended but also can replace an existing field.
