Comment:
Add user-defined type feature to the long term plan

    * Tajo catalog needs to support HCatalog or needs to be compatible to Hive meta.
   * The native columnar execution engine
   * Cost-based optimization which also includes a rewrite rule engine and various rewrite
rules   
+  * User-defined type (UDT)
+   * With UDT, in addition to primitive types (e.g., int, float..), Tajo will use a structured
data type as a column data type.
+   * It would be a powerful complementary means of the relational data model.
  
  == Short/Mid Term Plan ==
   * Improvement of the DAG framework
