More complex queries and more data require more powerful data warehouse platforms. SQL-MapReduce (SQL-MR) is a solution specifically designed for advanced analytical queries. It's the result of combining the most popular database language, SQL, with a programming model created by Google, MapReduce.
The goal of MapReduce is to distribute as much of the processing over as many processors as possible. In this on-demand webcast, independent analyst Rick van der Lans describes the SQL-MR implementation offered by nCluster, Aster Data's analytical database server. |
