Titan is a distributed graph database optimized for processing large-scale graphs represented over a cluster of machines. The pluggable storage architecture allows for any database to be configured to work with Titan. However, this distribution provides connectivity to both Cassandra and HBase. Titan is a native Blueprints enabled graph database and as such, it supports the full TinkerPop stack of technologies.

While the Titan project is getting on its way, please use the Gremlin users group at http://groups.google.com/group/gremlin-users for all Titan related discussions.

Graph graph = TitanFactory.open("/tmp/local-titan")
Vertex a = graph.addVertex();
Vertex b = graph.addVertex();
a.setProperty("name", "hercules");
b.setProperty("name", "cerberus");
Edge e = graph.addEdge(a, b, "battled");
e.setProperty("time", 12);
