The worst case for cassandra is random reads. You should ask youself a question,
do you really have this kind of workload in production ? If you really do, that
means cassandra is not the right tool for the job. Some product based on
berkeley db should work better, e.g. voldemort. Just plain old filesystem is
also good for 100% random reads (if you dont need to backup of course).
