Subject [jira] [Created] (HIVE-15977) Support standard ARRAY_AGG
Date Mon, 20 Feb 2017 05:48:44 GMT
Carter Shanklin created HIVE-15977:

             Summary: Support standard ARRAY_AGG
                 Key: HIVE-15977
             Project: Hive
          Issue Type: Sub-task
            Reporter: Carter Shanklin

SQL defines array_agg as a function that returns an array given a value expression in Section
10.9. Hive has something similar called collect_list. The SQL standard array_agg additionally
allows sorting by a value expression. It would be good to move to the standard and as a first
step it might be worthwhile to have array_agg as an alias and then to add support for sort
