Next on my technology plate: Apache Cassandra and Spring 3.1

I recently learned GIT and converted to it for all my projects at home. Next on my technology plate is Apache Cassandra NO SQL database and Spring 3.1, whose M1 was released today. I'm particularly interested in Spring support for environment profiles, basically a Spring native way to define different configurations for different environment. I hope what Spring has to offer will help us in building and deploying more efficiently.
