More importantly for the subject of MapReduce Design Patterns, a growing number of users brings along a growing number of experts. These experts are the ones that will drive the community’s documentation of design patterns not only by sharing new ones, but also by maturing the already existing ones.

In this chapter, we’ll discuss and speculate what the future holds for MapReduce design patterns. Where will they come from? What systems will benefit from design patterns? How will today’s design patterns change with the technology? What trends in data will affect the design patterns of today?

Trends in the Nature of Data

MapReduce systems such as Hadoop aren’t being used just for text analysis anymore. Increasing number of users are deploying MapReduce jobs that analyze data once thought to be too hard for the paradigm. New design patterns are surely to arise to deal with this to transform a solution from pushing the limits of the system to making it daily practice.

Images, Audio, and Video

One of the most obvious trends in the nature of data is the rise of image, audio, and video analysis. This form of data is a good candidate for a distributed system using MapReduce because these files are typically very large. Retailers want to analyze their security video to detect what stores ...
