As our applications grow and need to deal with new big data challenges and global distribution we look to new data stores designed to deal with these new challenges. Cassandra is one great tool to deal with both of these problems, we will go over some of the different ways of dealing with Cassandra from Grails. I will cover the various Cassandra plugins for grails, including the Cassandra ORM, Astyanax, and Cassandra GORM. Also, I will talk about using the Cassandra Java driver directly. By the end of the talk you should have a overview of the data modeling that will working well in Cassandra paired with Grails, when to use or not use each plugin, and some of the basic connection configuration details needed.
