Subject [jira] [Created] (HIVE-11756) Avoid redundant key serialization in RS for distinct query
Date Tue, 08 Sep 2015 09:10:47 GMT
Navis created HIVE-11756:
----------------------------

             Summary: Avoid redundant key serialization in RS for distinct query
                 Key: HIVE-11756
                 URL: https://issues.apache.org/jira/browse/HIVE-11756
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Navis
            Assignee: Navis
            Priority: Trivial


Currently hive serializes twice to know the length of distribution key for distinct queries.
This introduces IndexedSerializer to avoid this.
