Subject [jira] [Commented] (HIVE-8988) Support advanced aggregation in Hive to Calcite path
Date Fri, 12 Dec 2014 16:18:13 GMT


Jesus Camacho Rodriguez commented on HIVE-8988:

You'd better make sure that that function isn't pushed down.

I thought it would not be pushed through the GroupBy clause. Then, do you think it is better
to formulate it in the translation to Calcite as grouping_id(e1,...) instead of group_id()?
Then, as it is dependent on the other columns, it will not go down for sure.
