| |
| |
| <p><a class="externalLink" href="http://trafodion.incubator.apache.org">Apache Trafodion</a> is a webscale SQL-on-Hadoop solution enabling transactional or operational workloads on |
| <a class="externalLink" href="http://hadoop.apache.org" target="_blank">Hadoop</a>. The name .Trafodion. (the Welsh word for transactions, pronounced .Tra-vod-eee-on.) was chosen |
| specifically to emphasize the differentiation that Trafodion provides in closing a critical gap in the Hadoop ecosystem. 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. To learn more, see the <a class="externalLink" href="http://docs.trafodion.org/Trafodion_Product_Brief.pdf" target="_blank">Trafodion Product Brief (pdf 162 KB)</a></p> |
