Dave Brosius updated CASSANDRA-3772:
------------------------------------
Attachment: hashed_partitioner.diff
Moved existing RandomPartitioner code to AbstractHashedPartitioner, and added
abstract hash method. Created two subclasses, MD5Partitioner and
Murmur3Partitioner that extend and implement this method. Added back in a
deprecated RandomPartitioner class that identity-derives from MD5Partitioner
for backwards compatibility.
patch against trunk

> MD5 is a relatively heavyweight hash to use when we don't need cryptographic
> qualities, just a good output distribution. Let's see how much overhead we
> can save by using Murmur3 instead.
