I'm in the same boat. I've been looking at Neo4J, Titan, etc., as part of research for a new application I'm building. Our data set is fairly tiny (<<10M entities, almost certainly), but the information we're tracking is highly graph-oriented. I've been trying to decide between a graph db, which seems like a better fit for the real world relationships but is entirely new to me, and postgresql with exports to graph structures for analysis as needed. In particular, I'd be interested in deployment experiences with Orient and other graph dbs. I don't have a sys admin and I'm not one myself, so a PaaS platform is highly attractive. Neo4J has a Heroku "try" option, but there's no clear upgrade path. Titan is flexible in terms of backing store (Cassandra, PersistIt, etc.), but seems to require self-admin. Anyone deployed and maintained OrientDB or any of these other tools?

In your research, have you found any good graph database not written in Java?

  Triple/Quad stores (specialisation of a Graph DB for storing RDF) are available written in C (4Store, Virtuoso) as well as Lisp (AllegroGraph). They support a standardised query language called SPARQL which is based on matching graph patterns.

  I'm building the app in Java, so I specifically looked for those. Almost all of them have REST built-in (or easily available via the stack at http://www.tinkerpop.com http://www.tinkerpop.com), so the client could be language-agnostic. Look at http://bulbflow.com http://bulbflow.com for Python, for instance.

  ArangoDB (C/C++, http://www.arangodb.org/ http://www.arangodb.org/) Here you have 15 Graph databases compared: https://docs.google.com/spreadsheet/ccc?key=0AlHPKx74VyC5dERyMHlLQ2lMY3dFQS1JRExYQUNhdVE#gid=0 https://docs.google.com/spreadsheet/ccc?key=0AlHPKx74VyC5dER...

Heroku will have another Neo4j option in January that will offer an upgrade path. Disclaimer: I work for Heroku on Add-ons.
