* Summarization patterns: get a top-level view through summarizing and grouping facts
* Filtering patterns: view information subsets equivalent to documents generated from one person
* Data association patterns: reorganize info to paintings with different platforms, or to make MapReduce research more straightforward
* Join patterns: research varied datasets jointly to find fascinating relationships
* Metapatterns: piece jointly numerous styles to unravel multi-stage difficulties, or to accomplish a number of analytics within the comparable activity
* Input and output patterns: customise how you use Hadoop to load or shop facts
"A transparent exposition of MapReduce courses for universal facts processing patterns—this e-book is indespensible for somebody utilizing Hadoop."
