                     <p>
                         Ignite File System (IGFS) is a plug-and-play in-memory file system,
                         compatible with Hadoop Distributed File System (HDFS) and In-Memory Map Reduce.
                     </p>
                     <div class="page-heading">Dual Mode</div>
                     <p>
                         IGFS supports dual-mode that allows it to work as either a standalone file system in Hadoop cluster,
                         or work in tandem with HDFS, providing a primary caching layer for the secondary HDFS.
                         As a caching layer it provides highly configurable <em>read-through</em> and <em>write-through</em> behaviour.
                     </p>
                 </div>

             <div class="page-heading">Write-Through & Read-Through</div>
             <p>
                 Ignite In-Memory File System can be configured with a Hadoop native <code>Secondary File System</code>.
                 Such implementation allows for <em>read-through</em> and <em>write-through</em> behavior over any
                 other Hadoop FileSystem implementation (e.g. HDFS).
             </p>
             <p>
                 This allows IGFS serve as an in-memory caching layer over disk-based HDFS or any other
                 Hadoop-compliant file system.
