xuyang commented on FLINK-34301:
--------------------------------
Window TVF aggregation supports changelog stream is ready for testing. User
can add a window tvf aggregation as a down stream after CDC source or some
nodes that will produce cdc records.
Someone can verify this feature with:
# Prepare a mysql table, and insert some data at first.
# Start sql-client and prepare ddl for this mysql table as a cdc source.
# You can verify the plan by `EXPLAIN PLAN_ADVICE` to check if there is a
window aggregate node and the changelog contains "UA" or "UB" or "D" in its
upstream.
# Use different kinds of window tvf to test window tvf aggregation while
updating the source data to check the data correctness.
> Release Testing Instructions: Verify FLINK-20281 Window aggregation supports
