 The model behind Beam evolved from a number of internal Google data processing projects, including [MapReduce](http://research.google.com/archive/mapreduce.html), [FlumeJava](http://research.google.com/pubs/pub35650.html), and [Millwheel](http://research.google.com/pubs/pub41378.html). This model was originally known as the “[Dataflow Model](http://www.vldb.org/pvldb/vol8/p1792-Akidau.pdf)”.
