I've got a guy doing a code test for us and he has some questions about custom partitioners:
Wondering if anyone could chime in.
I'm curious as to why you don't just use the OrderPreservingPartitioner and apply the transformation to the email addresses in the application before you use them as keys.
One of the problems with Cassandra is that you can only use one partitioner for the whole cluster.
When I've looked at using it, it has always been clear that key choice is vital for range scans to be at all useful.
