Titan is a new real-time, distributed, transactional graph database that can use either Cassandra or HBase as its distributed data store.<p>Titan 0.3 was stressed tested with Cassandra at 120 billion edges and is capable of loading 1.2 million edges per second on a 16 machine hi1.4xl cluster (<a href="https://twitter.com/aureliusgraphs/status/316255164719828992" rel="nofollow">https://twitter.com/aureliusgraphs/status/316255164719828992</a>).<p>This release provides a complete performance-driven redesign of many core components, and the primary new feature is advanced indexing.<p>Here are the new indexing features:<p>* Geo: Search for elements using shape primitives within a 2D plane.<p>* Full-text: Search elements for matching string and text properties.<p>* Numeric range: Search for elements with numeric property values using intervals.<p>* Edge: Edges can be indexed as well as vertices.<p>See <a href="http://thinkaurelius.com/news/" rel="nofollow">http://thinkaurelius.com/news/</a>
One of the most interesting part seems not to be mentioned: Apache license.<p>So far the only real, all-features-included graph database with a permissive open source license, - or am I missing something?
I'd love to see more detailed write up about the performance. I'm working on a natural language parsing problem and have had some success using graphs to perform chunking in the past.<p>+1 for using Gremlin! Do you know of any python implementations of it?
