Yes, you need to implement the org.apache.cassandra.dht.IPartitioner interface,
there are a couple of abstract implementations you could base it on.

I'm not endorsing the idea of doing this, but as a hack to see if the effects
you could use the BOP and format the keys as (python):
str(key % 2) + "{0:0>#10}".format(key)
So all keys are 11 digit strings, even keys start with 0 and odd with 1.
Hope that helps.
