+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.

I think it is not necessary here because this section addresses tables.
> Rename the section of 'File Formats' to 'Data Formats' and fill compression
> section of the 'Table Management' chapter

> 'File format' is a legacy name, so we need to change it.
> In addiiton, the compression section still remains empty, even though we
> already have some descriptions in the compression section. This makes many
> users suffer from the difficulty of finding documents about compression.
