I spent some time since the FoundationDB open sourcing announcement last week putting together the first, crude version of a FoundationDB storage adapter for the JanusGraph graph database. JanusGraph is LinuxFoundation hosted fork of TitanDB. We’ll be evaluating it to see if FDB a good fit for the JanusGraph access patterns/use cases but on the face of it, Janus is lacking a good, distributed ACID option for folks, and I think FDB is quite compelling in this department. I plan on picking the experts brains here as I get a bit further along to make sure my implementation/data modeling is sympathetic with FDB best practices.
In the meantime, if anyone is interested in living dangerously, the work in progress can be found here.
