    • HIVE-352. Column-based storage format RCFile. (Yongqiang He via zshao)

    Description

      column based storage has been proven a better storage layout for OLAP.
      Hive does a great job on raw row oriented storage. In this issue, we will enhance hive to support column based storage.
      Acctually we have done some work on column based storage on top of hdfs, i think it will need some review and refactoring to port it to Hive.

      Any thoughts?
