This might a stupid question but is this competing with Neo4j or Giraph? I didn't see a mention of comparison with either in the docs. I believe graph data storage and graph processing are two different things - is TItan doing both?

Some benchmarks against other graphdbs (but it was with Titan 0.3): http://euranova.eu/upl_docs/publications/an-empirical-compar...

If you're looking for more up-to-date information about Titan's capabilities then check out these posts.

Titan underwent major changes to optimize in-memory operations. Here is some up-to-date info on that: http://thinkaurelius.com/2013/11/24/boutique-graph-data-with...

IIRC, the euranova benchmark doesn't discuss scalability. This post does: http://thinkaurelius.com/2013/05/13/educating-the-planet-wit...

Some nice changes in this release. Having built-in TTL on edges and vertices would have simplified several different system's I've worked on.

Titan provides both graph analytic (OLAP) and graph database capabilities (OLTP). For more information, please read:

http://thinkaurelius.com/2013/05/13/educating-the-planet-wit... (cluster-sized graphs OLTP)

http://thinkaurelius.com/2012/11/11/faunus-provides-big-grap... (OLAP engine)

http://thinkaurelius.com/2013/11/24/boutique-graph-data-with... (single-machine sized graphs OLTP)

For those interested in Titan 1.0 roadmap and the evolution of the Titan OLTP/OLAP story. Titan will be implementing TinkerPop3 API http://www.tinkerpop.com/docs/current/ ... Currently, Titan 0.5.0 leverages the Faunus Gremlin compiler (http://faunus.thinkaurelius.com), but with TinkerPop3, TinkerPop3 provides an OLAP compiler for Gremlin that will make things easier for Titan as well as other graph computing engines implementing the stack http://www.tinkerpop.com/docs/current/#traversalvertexprogra...

I would love to hear about peoples experiences working with Titan (or other graph dbs, for that matter) - I've been following the project with interest for some time now.

If you don't want to comment on HN I'd really appreciate an email to craig dot glennie gmail
