I'm thinking of this kind of patterns:
If there are nodes n and n' such that
- there's an edge from n to n' and
- n has a label XY
So what I'd want to do is match basic patterns and then add nodes, edges, and labels.

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…
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. http://thinkaurelius.com/2012/10/25/a-solution-to-the-supernode-problem/ 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…
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.

Does anyone know if this supports (efficient) graph-rewriting? I'm thinking of this kind of patterns: If there are nodes n and n' such that - there's an edge from n to n' and - n has a label XY then add label Y to n' So what I'd want to do is match basic patterns and then add nodes, edges, and labels.

There is support for graph rewriting for a Titan-backed data-set using Faunus. Titan does not support global graph operations. Therefore, Faunus was created to allow you to perform offline graph operations much like the one you've described.
