+Using compression can make data size compact, thereby enabling efficient
use of network bandwidth and storage. Most of Tajo data formats support data
compression feature.
+Currently, compression configuration affects only for stored data format
and it is specified when a table is created as table meta information(See
`Create Table <../sql_language/ddl.html#create-table>`_).
+Compression for intermidate data or others is not supported now.
