Jark Wu commented on FLINK-7446:
--------------------------------
In the long run, we can provide a new interface called {{DefinedWatermark}},
which has two methods {{getRowtimeAttribute}} (can only be an existing field)
and {{getWatermarkGenerator}}. The {{DefinedRowtimeAttribute}} will be marked
deprecated. In addition, we can provide some built-in watermark generators,
such as {{AscendingTimestamp}}, {{BoundedOutOfOrderness}}. What do you think ?
> Support to define an existing field as the rowtime field for TableSource

> 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.
