Subject [jira] [Commented] (HIVE-11955) Add costing for join-groupby transpose rule
Date Fri, 13 Nov 2015 09:31:11 GMT

Jesus Camacho Rodriguez commented on HIVE-11955:
------------------------------------------------

+1, LGTM.

It makes sense to delegate the logic of choosing to the Planner, as other planner implementation
(e.g. Volcano) might decide to continue firing up rules on both alternative plans.
