+<h1>OpenStack Swift Integration<a class="headerlink" href="#openstack-swift-integration" title="Permalink to this headline">¶</a></h1>
+<p>Tajo supports OpenStack Swift as one of the underlying storage types.
+In Tajo, Swift objects are represented and recognized by the same URI format as in Hadoop.</p>
+<p>You don’t need to run Hadoop to run Tajo on Swift, but need to configure it.
+You will also need to configure Swift and Tajo.</p>
+<p>For details, please see the following sections.</p>
+<div class="section" id="swift-configuration">
+<h2>Swift configuration<a class="headerlink" href="#swift-configuration" title="Permalink to this headline">¶</a></h2>
+<p>This step is not mandatory, but is strongly recommended to configure the Swift’s proxy-server with <code class="docutils literal"><span class="pre">list_endpoints</span></code> for better performance.
+More information is available <a class="reference external" href="http://docs.openstack.org/developer/swift/middleware.html#module-swift.common.middleware.list_endpoints">here</a>.</p>

+<h2>Hadoop configurations<a class="headerlink" href="#hadoop-configurations" title="Permalink to this headline">¶</a></h2>

+<p>In Tajo, a table is a logical view of one data sources. Logically, one table consists of a logical schema, partitions, URL, and various properties. Physically, A table can be a directory in HDFS, a single file, one HBase table, or a RDBMS table. In order to make good use of Tajo, users need to understand features and physical characteristics of their physical layout. This section explains all about table management.</p>

+<p>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 enabled when a table is created with the proper table property(See <a class="reference external" href="../sql_language/ddl.html#create-table">Create Table</a>).</p>
