I'd vote against changing the existing CLUSTER since the existing CLUSTER
while not great does handle many different key values fairly well as well
and this solution wouldn't. Many different key values are still
useful to cluster if you're doing searches over ranges since it lowers the
number of heap file reads necessary. If done this should probably be
separate from the existing cluster or at least both versions should be
possible.
