+Derby Configuration
+=========================
+
+By default, Tajo uses `Apache Derby <http://db.apache.org/derby/>`_ as a
persistent storage in order to manage table meta data. So, without any
configuration, you can use Derby for catalog store.
+
+Also, you can set manually configs in ``conf/catalog-site.xml`` as follows:
+
+.. code-block:: xml
+
+ <property>
+ <name>tajo.catalog.store.class</name>
+ <value>org.apache.tajo.catalog.store.DerbyStore</value>
+ </property>
+
+ <property>
+ <name>tajo.catalog.uri</name>
+ <value>jdbc:derby:<absolute directory>;create=true</value>
+ </property>
+
+Since Derby is a file-based embedded database, it stores data into a
specified directory. So, you need to specify the directory for storing data
files instead of specifing JDBC URI with hostname and port. For example, in
case where you use '/var/data/tajo-catalog' as a derby store directory, you
should set configs as follows:
