Subject How even distributed is MD5 Hash in RandomPartitioner
Date Mon, 16 Nov 2009 17:59:36 GMT
Hi everyone,

Since Cassandra uses MD5 hash internally to hash the keys to place on
the ring in a RandomPartitioner, how evenly distributed are the hashes
across the hash space?

Does it make sense to divide the hash space equally by the number of
machines available using InitialToken(ie, If there are 10 machines,
each will handle 1/10th of maximum hash value) and expect that the
machines will get a reasonably equal load?

Thanks
Ray
