Jark Wu commented on FLINK-17868:
---------------------------------
Hi [~qingyue], I'm perfer the Alternative#1, because we should keep the
semantic/behavior consistent between streaming and batch.
{{CURRENT_TIMESTAMP()}} is not a synonyms for {{PROCTIME()}}.
Regarding to the implementation, I think we can try to merge
{{AbstractProcessStreamOperator}} into {{TableStreamOperator}}, then streaming
and batch operators can share the same base class.
I assigned this issue to you.
