Coming in 1.2: Collections support in CQL3

Apache Cassandra is a distributed database system that encourages denormalization instead of joins to improve performance. However, this approach can make some simple patterns less elegant. To address this issue, Cassandra 1.2 introduces three new CQL3 types: map, set, and list. These collection types provide more powerful and natural alternatives for handling multiple email addresses or other similar scenarios. The operations allowed on these collections include setting values, adding elements, removing elements by index or value, and updating specific elements. Collection support is already available in the Cassandra trunk and will be part of the final release of CQL3 in Cassandra 1.2.
