Jark Wu updated FLINK-21327:
----------------------------
Parent: FLINK-23997
Issue Type: Sub-task (was: New Feature)
> Support window TVF in batch mode
> --------------------------------
>
> Key: FLINK-21327
> URL: https://issues.apache.org/jira/browse/FLINK-21327
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Reporter: Jark Wu
> Assignee: JING ZHANG
> Priority: Major
>
> As a batch and streaming unified engine, we should also support to run window
> TVF in batch mode. Then users can use one query with streaming mode to
> produce data in real-time and use the same query with batch mode to backfill
> data for a specific day.
> The implementation for batch should be straightforward and simple. We can
> just introduce a physical and exec node for window TVF.
