> 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.
