Partitioner
Partitioner: any IPartitioner may be used, including your own as long as it is on the classpath. Out of the box, Cassandra provides org.apache.cassandra.dht.RandomPartitioner, org.apache.cassandra.dht.OrderPreservingPartitioner, and org.apache.cassandra.dht.CollatingOrderPreservingPartitioner. (CollatingOPP colates according to EN,US rules, not naive byte ordering. Use this as an example if you need locale-aware collation.) Range queries require using an order-preserving partitioner.
