WebComplex algorithms have been coded into frameworks so that programmers can use them. MapReduce runs across a network of low-cost commodity devices, so companies don't require a whole department of Ph.D. scientists to model data, nor do they need a supercomputer to handle enormous volumes of data. Top 3 Stages of MapReduce. Top … WebMapReduce Algorithm is mainly inspired by the Functional Programming model. It is used for processing and generating big data. These data sets can be run simultaneously and distributed in a cluster. A MapReduce …
