Last year I blogged about an initiative to take TitanDb to the Apache Foundation as an incubation project. Yesterday, the next step for TitanDb was announced, when the Linux Foundation welcomed JanusGraph, a project which uses TitanDb as its starting point. The current documentation will look familiar to anyone who has investigated TitanDb, but the news will be welcomed by the TitanDb community. So it's worth keeping an eye on the JanusGraph website.
Since earlier this year when I started trying to get a better handle on the breadth of graph database options available for a developer, Titan has been an option I have kept in regular contact with. It's fair to say there has been a lot of uncertainty about the prospects for Titan. But there have been some interesting developments regarding Titan during the summer. IBM Graph has reached GA on Bluemix, albeit with only REST access, which may not appeal to Java developers, particularly those familiar with Titan and comfortable with natively handling vertices and edges. And more recently there has been a lot of work on integrating Titan with ScyllaDb, which provides a long-term option for using Thrift as a communication mechanism between Titan and the backend database.
