Subject [jira] [Created] (HIVE-4245) Implement numeric dictionaries in ORC
Date Thu, 28 Mar 2013 15:43:15 GMT
Owen O'Malley created HIVE-4245:

             Summary: Implement numeric dictionaries in ORC
                 Key: HIVE-4245
             Project: Hive
          Issue Type: New Feature
          Components: Serializers/Deserializers
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley

For many applications, especially in de-normalized data, there is a lot of redundancy in the
numeric columns. Therefore, it would make sense to adaptively use dictionary encodings for
numeric columns in addition to string columns.
