Many people mistakenly assume that MapReduce is only useful when dealing with Google or Facebook scale datasets. Nowadays, MapReduce is simply a convenient data access pattern, particularly when your data is spread across multiple machines. For example, Riak employs the MapReduce paradigm as its "primary querying and data-processing system." [0] Clearly, Riak does not expect each and every query to run for hours and involve TBs of data. MapReduce is just a straightforward way to process distributed data. [0] http://wiki.basho.com/MapReduce.html http://wiki.basho.com/MapReduce.html
