> 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.
