Trafodion is an open-source webscale SQL-on-Hadoop DBMS solution that extends and builds on Apache Hadoop. Its name is the Welsh word for "transactions" (pronounced "Tra-vod-eee-on") because the developers wanted to emphasize the fact that one specific way it extended Hadoop was through guaranteed transactional integrity. By doing so, it targets big data transactional and operational workloads rather than analytic workloads. It is ACID-compliant and has fully-functional ANSI SQL support
