Subject [jira] [Created] (HIVE-4914) filtering via partition name should be done inside metastore server

--------------------------------------

             Summary: filtering via partition name should be done inside metastore server
                 Key: HIVE-4914
                 URL: https://issues.apache.org/jira/browse/HIVE-4914
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
            Reporter: Sergey Shelukhin


Currently, if the filter pushdown is impossible (which is most cases), the client gets all
partition names from metastore, filters them, and asks for partitions by names for the filtered
set.

Metastore server code should do that instead; it should check if pushdown is possible and
do it if so; otherwise it should do name-based filtering.

Saves the roundtrip with all partition names from the server to client, and also removes the
need to have pushdown viability checking on both sides.
