Hyunsik Choi commented on TAJO-284:
-----------------------------------

EXPRESSIONS field seems to contain redundant data. PARTITION, VALUES, LESS, 
THAN, and partition name all may be unnecessary. I think that EXPRESSIONS field 
should contain a single value for range and hash. For list, it should contain 
only value list. This approach would be easy to use indexes that RDBMS provides.

> To support table partitioning, Tajo catalog should supports the table 
> partitioning. Each partition entry should include partition table id, 
> partition key ids, partition types (i.e., hash, range, list, and key), 
> partition number, min, max, and hash id.
