Apache Giraph is an Apache project to perform graph processing on big data. Giraph utilizes Apache Hadoop's MapReduce implementation to process graphs. Facebook used Giraph with some performance improvements to analyze one trillion edges using 200 machines in 4 minutes.{{cite web|last=Ching|first=Avery|title=Scaling Apache Giraph to a trillion edges|url=http://www.facebook.com/notes/facebook-engineering/scaling-apache-giraph-to-a-trillion-edges/10151617006153920|publisher=Facebook|access-date=8 February 2014|date=August 14, 2013}} Giraph is based on a paper published by Google about its own graph processing system called Pregel.{{cite news|last=Jackson|first=Joab|title=Facebook's Graph Search puts Apache Giraph on the map|url=http://www.pcworld.com/article/2046680/facebooks-graph-search-puts-apache-giraph-on-the-map.html|access-date=8 February 2014|newspaper=PC World|date=Aug 14, 2013}} It can be compared to other Big Graph processing libraries such as Cassovary.{{cite web|last=Harris|first=Derrick|title=Facebook's trillion-edge, Hadoop-based and open source graph-processing engine|url=http://gigaom.com/2013/08/14/facebooks-trillion-edge-hadoop-based-graph-processing-engine/|archive-url=https://web.archive.org/web/20130816161123/http://gigaom.com/2013/08/14/facebooks-trillion-edge-hadoop-based-graph-processing-engine/|url-status=dead|archive-date=August 16, 2013|publisher=Gigaom|access-date=8 February 2014|date=Aug 14, 2013}}

As of September 2023, it is no longer actively developed.{{cite web|title=Apache Giraph - Apache Attic|url=https://attic.apache.org/projects/giraph.html}}
