   * '''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.

(CollatingOPP colates according to EN,US rules, not naive byte ordering.  Use 
this as an example if you need locale-aware collation.) The only difference 
between BOP and OPP is that OPP requires keys to be UTF-8 encoded. Range 
queries require using an order-preserving partitioner.
  
  Achtung!  Changing this parameter requires wiping your data directories, 
since the partitioner can modify the !sstable on-disk format.
