Actual Behavior

Delete from whole table doesn't trigger the CDC task.

The reason is that DELETE FROM an entire table internally invoke TRUNCATE, and TRUNCATE does not actually delete data row by row but instead recreates a new table

Expected Behavior

Delete whole table should trigger the cdc task update.

Steps to Reproduce

create cdc task.
insert rows.
and run delete table which will call truncate table.

delete from t;
