Longevity is a persistence framework for Scala and NoSQL. We currently support MongoDB, with a Cassandra back end coming soon. [UPDATE: We've had a Cassandra back end for a long time now. We now have a SQLite back end as well.] After having been working on this project for over a year, I am so excited to finally share it with you! I've been working hard to put in a core set of features that would make the tool feasible for you to use in a real application. The result is our MMP release, which we just put out yesterday.
