Hi Ramya,
Are you looking for "allow lateness" for tumbling window in Flink SQL?
If yes, Flink SQL doesn't provide such things currently.
However, blink planner (the new runner of Flink SQL) will support this
maybe in the next release (v1.10).
Actually, we already implemented it in blink planner but didn't expose the
feature in v1.9 to let us have enough time to review the API.
For now, you can convert Table to DataStream, and can use tumbling window
functionality on the DataStream which supports allow lateness.
Or you can increase the watermark delay to wait more late records, but the
window output delay will get larger.
Best,
Jark
