In v6.5.0, this feature is now compatible with TiCDC and PITR and becomes GA. This feature helps you to easily undo DML misoperations for filter conditions connected by AND in the WHERE clause. In this way, the index merge of TiDB can now cover more general combinations of query filter conditions and is no longer limited to union (OR) relationship
