I'm currently playing around with it for a large internal development project. My only concern (and why I'm leaning towards using Neo4j at least initially) is that I don't really yet have a good indication if I'm going to be dealing with enough data to warrant a big distributed solution.

I'm actually right now mostly messing with TinkerGraph (an in memory graph database that's part of the Tinkerpop utilities that the Titan guys make).

With Titan/BerkeleyDB you will get blazing performance for a single-machine distribution. One of the wonderful innovations of Titan is vertex-centric indices that is even necessary at single-machine scale.

Next, if you decide to scale horizontally, then you can simply change the storage.backend=cassandra and thats that (of course, you need to do a bulk data transfer from BerkeleyDB to Cassandra).

That's good to know actually; I think that'll probably be a good approach for my application.

For what it's worth, it was seeing a video of you giving a talk about Titan that made me start looking into it. It seems super neat.
