The best thing to do is start with a look at ByteOrderedPartitoner and AbstractByteOrderedPartitioner.
You'll want to create a new TimeUUIDToken extends Token<UUID> and a new UUIDPartitioner that extends AbstractPartitioner<> Usual disclaimer that ordered partitioners cause problems with load balancing. Hope that helps. ----------------- Aaron Morton Freelance Cassandra Consultant New Zealand @aaronmorton http://www.thelastpickle.com On 25/03/2013, at 1:12 AM, Carlos Pérez Miguel <cperez...@gmail.com> wrote: > Hi, > > I store in my system rows where the key is a UUID version1, TimeUUID.
