   @EmmyMiao87 can you help to review the code change of Planer?
   Basically,  when user enabled unique key merge-on-write, we don't need to merge the data with same keys to ensure which row is latest, old row is marked as deleted in DeleteBitmap. So we can enable pre-aggregation to accelerate the query execution, just like processing data in duplicate keys table.
