+Tablespaces
+===========
+
+Tablespaces is a physical location where files or data objects representing data rows can be stored. Once defined, a tablespace can be referred to by a name when creating a database or a table. Especially, it is very useful when a Tajo cluster instance should use heterogeneous storage systems such as HDFS, MySQL, and Oracle because each tablespace can be specified to use a different storage system.

 In other words, an empty field is basically recognized as a ``NULL`` value in Tajo.
 If a field domain is ``TEXT``, an empty field is recognized as a string value ``''`` instead of ``NULL`` value.
