Longevity is the persistence framework to use with Scala and NoSQL. Release 0.17 simplifies the user API in some very pleasant ways. Empty marker traits Persistent and Embeddable are removed. Also, KeyVal now takes a single type parameter instead of two. In brief, this will make defining the classes you want to persist so much easier and more natural, as you no longer have to extend your persistent classes with empty marker traits.

Longevity Artifacts for Scala 2.11 and 2.12
So I've finally got the longevity build set up to publish artifacts for Scala versions 2.11 and 2.12! I'm a little behind on the game, but, I've been busy ;-). Please use longevity version 0.16.1 for 2.12 artifacts. I'll be publishing artifacts for both Scala versions moving forward.
I'd like to shout out to the wonderful people at ScalaTest - Bill Venners and Chua Chee Seng - for helping me resolve an interoperability issue that made the longevity 2.12 artifacts possible. Thanks again!

Partition Keys in Longevity
I'm so excited to announce the release of longevity version 0.16.0! Longevity now supports partition keys - a key where, given a key value, we can determine the node in a distributed database where the data resides (or would reside, if it existed). This is a critical feature for NoSQL databases in a distributed context. A partition key is implemented with sharding in MongoDB, and with partitioning in Cassandra.
I'll provide a brief example of a partition key here after the jump, but to learn more about it, please take a look at the user manual.
