HadoopDB

HadoopDB: An Architectural Hybrid of MapReduce and DBMS Technologies for Analytical Workloads.

HadoopDB is:

• A hybrid of DBMS and MapReduce technologies that targets analytical workloads
• Designed to run on a shared-nothing cluster of commodity machines, or in the cloud
• An attempt to fill the gap in the market for a free and open source parallel DBMS
• Much more scalable than currently available parallel database systems and DBMS/MapReduce hybrid systems.
• As scalable as Hadoop, while achieving superior performance on structured data analysis workloads
