Subject [jira] [Updated] (CASSANDRA-3772) Evaluate Murmur3-based partitioner
Date Tue, 27 Mar 2012 02:57:29 GMT


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.

> 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
