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. ----------------- Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 14/08/2012, at 7:33 AM, A J <s5a...@gmail.com> wrote: > Is it possible to use a custom Partitioner type (other than RP or BOP) ? > Say if my rowkeys are all Integers and I want all even keys to go to > node1 and odd keys to node2, is it feasible ?
