    <h3>Performance &amp; scalability</h3>
    <p>
      Spark SQL includes a cost-based optimizer, columnar storage and code generation to make queries fast.
      At the same time, it scales to thousands of nodes and multi hour queries using the Spark engine, which provides full mid-query fault tolerance.
      Don't worry about using a different engine for historical data.

    <h3>Community</h3>
    <p>
      Spark SQL is developed as part of Apache Spark. It thus gets
      tested and updated with each Spark release.
    </p>
    <p>
      If you have questions about the system, ask on the
      <a href="/community.html#mailing-lists">Spark mailing lists</a>.
    </p>
    <p>
      The Spark SQL developers welcome contributions. If you'd like to help out,
      read <a href="/contributing.html">how to
      contribute to Spark</a>, and send us a patch!
