<div class="span4 bottom-description">
<blockquote><a href="http://trafodion.apache.org/">Apache Trafodion</a> is a webscale SQL-on-Hadoop solution enabling transactional or operational
workloads on Hadoop. <br /><br />The name &quot;Trafodion&quot; (the Welsh word for transactions, pronounced
&quot;Tra-vod-eee-on&quot;) was chosen specifically to emphasize the differentiation that
Trafodion provides in closing a critical gap in the Hadoop ecosystem.<br /><br />
Trafodion builds on the scalability, elasticity, and flexibility of Hadoop. Trafodion extends
Hadoop to provide guaranteed transactional integrity, enabling new kinds of big data
applications to run on Hadoop.</blockquote>

<span>Disclaimer: Apache Trafodion is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making
process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the
completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</span>
