-----------------------------------
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.
