    Description

      At present, there is no chance to modify the DataStreamRel tree after the volcano optimization. We consider to add a decoration phase after volcano optimization phase. Decoration phase is dedicated for rewriting predicated logical plan and is independent of cost module. After decoration phase is added, we get the chance to apply retraction rules at this phase.
