    * As I mentioned above,  Tajo uses CSV as the intermediatee data format. It may cause CPU overhead and is relatively large to be transmitted via networks. We need to change it.
   * JDBC/ODBC drivers
    * Tajo is a relational DW system. If we have such connectors, it can be easily integrated with existing BI and OLAP tools.

    * It's very useful for web-based applications.
   * Proper resource allocation for SubQuery (i.e., Execution Block in PPT)
