[jira] [Created] (HIVE-7509) Fast stripe level merging for ORC

Prasanth J created HIVE-7509:
--------------------------------

             Summary: Fast stripe level merging for ORC
                 Key: HIVE-7509
                 URL: https://issues.apache.org/jira/browse/HIVE-7509
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.14.0
            Reporter: Prasanth J
            Assignee: Prasanth J


Similar to HIVE-1950, add support for fast stripe level merging of ORC files through CONCATENATE command and conditional merge task. This fast merging is ideal for merging many small ORC files to a larger file without decompressing and decoding the data of small orc files.
