> 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.
