Canope Nerda commented on FLINK-29692:
--------------------------------------
Thanks [~jark] for suggesting the legacy group window agg. So last value in
your example is based on rowtime or proctime? Another problem in my case is
that we require time precision to be microsecond, but time attribute only
supports millisecond so far.
> 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: 1.15.2
> 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.
