[jira] [Created] (HIVE-4245) Implement numeric dictionaries in ORC

Owen O'Malley created HIVE-4245:
-----------------------------------

             Summary: Implement numeric dictionaries in ORC
                 Key: HIVE-4245
                 URL: https://issues.apache.org/jira/browse/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.
