Hyunsik Choi commented on TAJO-284:
-----------------------------------
If EXPRESSIONS contains all partitions as you mentioned, it cannot contain a
number of partitions and cannot utilize the indexing techniques of underlying
RDBMS. In my opinion, each partition should be one row.
> Add table partitioning entry to Catalog

> 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.
