Jark Wu commented on FLINK-29692:
---------------------------------
I think early fire / late arrival is a great feature, but I just want to
explore if we have other or better solutions for the use case because
supporting early fire / late arrival on the new window TVF might not be easy.
> Support early/late fires for Windowing TVFs

> Key: FLINK-29692
> URL: https://issues.apache.org/jira/browse/FLINK-29692
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / Planner
> Affects Versions: 1.15.3
> Reporter: Canope Nerda
> Priority: Major
>
> I have cases where I need to 1) output data as soon as possible and 2) handle
> late arriving data to achieve eventual correctness. In the logic, I need to
> do window deduplication which is based on Windowing TVFs and according to
> source code, early/late fires are not supported yet in Windowing TVFs.
> Actually 1) contradicts with 2). Without early/late fires, we had to
> compromise, either live with fresh incorrect data or tolerate excess latency
> for correctness.
