Aster Data SQL-MapReduce Technology Patent
From a Teradata PR announcement:
SQL-MapReduce® is a framework which enables fast, investigative analysis of complex information by data scientists and business analysts. It enables procedural expressions in software languages (such as Java, C#, Python, C++, and R) to be parallelized across a group of linked computers (compute cluster) and then activated for use (invoked) with standard SQL.
The closest open source solution I can think of is Pig , created and open sourced by Yahoo! (PDF).
