[jira] [Created] (HIVE-9418) ORC production of encoded data, cache usage

Sergey Shelukhin created HIVE-9418:
--------------------------------------

             Summary: ORC production of encoded data, cache usage
                 Key: HIVE-9418
                 URL: https://issues.apache.org/jira/browse/HIVE-9418
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sergey Shelukhin


ORC needs to be able to read self-contained rowgroups and return them. It should use low-level cache in process. In future, we may use high-level cache to cache rowgroups instead
