The MapReduce algorithmic pattern may be Google's secret weapon for dealing with enormous quantities of data, but many programmers only see it as intimidating and obscure. In this video master class, data expert Pete Worden shows you how to build simple MapReduce jobs, using concrete use cases and descriptive examples to demystify the approach. All you need to get started is basic knowledge of Python and the Unix shell.

Worden demonstrates what happens when 500 million records are loaded into a database the traditional way: performance falls off dramatically once the working set is larger than memory. Discover how to solve the problem by introducing a sorting step—the method that lies at the heart of MapReduce.
