The new MongoDB Scala Driver[1] provides a modern idiomatic Scala driver for MongoDB. Built on top of the MongoDB Async Java Driver (3.1) it provides a first class Scala experience. All database calls are asynchronous and return an Observable allowing for efficient execution, concise code, and functional composition[2].
As this is a release candidate it is not recommended for production use. However, we would greatly appreciate feedback from the user community.
As always, please let us know if you have any problems by opening an issue at https://jira.mongodb.org/browse/SCALA.
