Faunus is a property graph analytics engine based on Hadoop. A breadth-first version of the graph traversal language Gremlin operates on a vertex-centric property graph data structure. Faunus can be extended with new operations written using MapReduce and Blueprints.

Faunus was renamed Titan-Hadoop and merged into Titan as of version 0.5.0. Faunus is now part of and maintained in the same repository as Titan. It is contained in the Titan release downloads and pushed to Maven Central as the titan-hadoop module. The Faunus documentation in version 0.5.0 and later is part of the Titan manual available at http://s3.thinkaurelius.com/docs/titan/current/. The code and wiki documentation in this repository only cover Faunus versions 0.4 and earlier.
