A data transformation and aggregation technology proven at extreme scale that works on key value pairs and consists of three transformation stages - map (a general transformation of the input key value pairs), shuffle (brings all pairs with the same key together) and reduce (an aggregation of all pairs with the same key). Part of the original Hadoop code base, becoming an Apache Hadoop sub-project in July 2009.
