mongodb oss admin tools

Rose Toomey

Rose Toomey is the creator of Salat, a simple serialization for Scala and MongoDBSalat was developed to make using Scala with Casbah and MongoDB as simple as possible. While Casbah increased the usability of the mongo-java-driver in Scala, there was no correspondingly elegant solution for serializing and deserializing objects. The new horizons opened up by using MongoDB as a document store demanded something better than the complexity and ceremony of the ORMs I’d worked with in the past. I also faced the challenge that my company, Novus Partners, is a financial startup that needs to process massive amounts of data very quickly. What to do? Enter Salat: it not only serializes to and from Mongo documents quickly, but uses hi-fi type information provided by the Scala compiler instead of explicit mappings. No fuss, no muss: my goal is that someone who wants to use Scala and MongoDB can be up and running with Salat in fifteen minutes.
