+Connecting to the Tajo cluster instance
+=======================================
+A Tajo cluster is represented by a URL. Tajo JDBC driver can take the
following URL forms:
+
+ * ``jdbc:tajo://host/``
+ * ``jdbc:tajo://host/database``
+ * ``jdbc:tajo://host:port/``
+ * ``jdbc:tajo://host:port/database``
+
+Each part of URL has the following meanings:
+
+ * ``host`` - The hostname of the TajoMaster. You can put hostname or ip
address here.
+ * ``port`` - The port number that server is listening. Default port number is
26002.
+ * ``database`` - The database name. The default database name is ``default``.
+
+ To connect, you need to get ``Connection`` instance from Java JDBC Driver
Manager as follows:
+
+.. code-block:: java
+
+ Connection db = DriverManager.getConnection(url);
+
+
+Connection Parameters
+=====================
+Connection parameters lets the JDBC Copnnection to enable or disable
additional features. You should use ``java.util.Properties`` to pass your
connection parameters into ``Connection``. The following example means that the
transmission of ResultSet uses compression and its connection timeout is 15
seconds.
+
+.. code-block:: java
+
+ String url = "jdbc:tajo://localhost/test";
+ Properties props = new Properties();
+ props.setProperty("useCompression","true"); // use compression for ResultSet
+ props.setProperty("connectTimeout","15000"); // 15 seconds
+ Connection conn = DriverManager.getConnection(url, props);
+
+The connection parameters that Tajo currently supports are as follows:
+
+ * ``useCompression = bool`` - Enable compressed transfer for ResultSet.
+ * ``defaultRowFetchSize = int`` - Determine the number of rows fetched in
ResultSet by one fetch with trip to the Server.
+ * ``connectTimeout = int (seconds)`` - The timeout value used for socket
connect operations. If connecting to the server takes longer than this value,
the connection is broken. The timeout is specified in seconds and a value of
zero means that it is disabled.
+ * ``socketTimeout = int (seconds)`` - The timeout value used for socket read
operations. If reading from the server takes longer than this value, the
connection is closed. This can be used as both a brute force global query
timeout and a method of detecting network problems. The timeout is specified in
seconds and a value of zero means that it is disabled.
+ * ``retry = int`` - Number of retry operation. Tajo JDBC driver is resilient
against some network or connection problems. It determines how many times the
connection will retry.

-You can use ``ALTER TABLE ADD PARTITION`` to add partitions to a table. The
location must be a directory inside of which data files reside. If the location
doesn't exist on the file system, Tajo will make the location by force. ``ADD
PARTITION`` changes the table metadata, but does not load data. If the data
does not exist in the partition's location, queries will not return any
results. An error is thrown if the partition for the table already exists. You
can use ``IF NOT EXISTS`` to skip the error.
+You can use ``ALTER TABLE DROP PARTITION`` to drop a partition for a table.

+REPAIR PARTITION
========================
+Tajo stores a list of partitions for each table in its catalog. If partitions
are manually added to the distributed file system, the metastore is not aware
of these partitions. Running the ``ALTER TABLE REPAIR PARTITION`` statement
ensures that the tables are properly populated.

- ALTER TABLE table1 DROP PARTITION (col1 = 'TAJO' ) PURGE
+.. note::
+
+ Even though an information of a partition is stored in the catalog, Tajo
does not recover it when its partition directory doesn't exist in the file
system.
-You can use ``ALTER TABLE DROP PARTITION`` to drop a partition for a table.
This removes the data for a managed table and this doesn't remove the data for
an external table. But if ``PURGE`` is specified for an external table, the
partition data will be removed. The metadata is completely lost in all cases.
An error is thrown if the partition for the table doesn't exists. You can use
``IF EXISTS`` to skip the error.
