The default OPP now does comparisons based strictly on byte order, and is no longer collation aware. This is a better default choice for those who don't need collation since it's much faster. If you do need collation, the old partitioner is still available as CollatingOPP:
- <Partitioner>org.apache.cassandra.dht.OrderPreservingPartitioner</Partitioner> + <Partitioner>org.apache.cassandra.dht.CollatingOrderPreservingPartitioner</Partitioner> If you have test data on trunk using the old OPP across more than one node, you need to use the CollatingOPP for the partitioning to match what you have on disk. -Jonathan
