             Summary: Add Table Partitioning
                 Key: TAJO-283
                 URL: https://issues.apache.org/jira/browse/TAJO-283
             Project: Tajo
          Issue Type: New Feature
          Components: catalog, physical operator, planner/optimizer
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 0.8-incubating


Table partitioning gives many facilities to maintain large tables. First of all, it enables
the data management system to prune many input data which are actually not necessary. In addition,
it gives the system more optimization  opportunities  that exploit the physical layouts.

Basically, Tajo should follow the RDBMS-style partitioning system, including range, list,
hash, and so on. In order to keep Hive compatibility, we need to add Hive partition type that
does not exists in existing DBMS systems.
