The Robot Army is a command-oriented general purpose distributed processing system, allowing arbitrary transform and aggregation operations over any size data set. It comes with a built-in data store layer, consisting of ordered sets of untyped, variable length records of any form. Command orientation, as contrasted with code orientation, provides significant benefits. The user can leverage skills by invoking largely the same commands as on a single machine. One need not even write new programs at all if they already exist and fit the mapreduce model. For example, many standard unix utilities can be used as is. In addition, writing new programs is made simple by the fact that the system is by nature language agnostic. There is no library API to learn, only STDIN, STDOUT, and STDERR. This allows the programmer to develop and test on a single machine with local sample data, the
