Jonathan Ellis resolved CASSANDRA-476.
--------------------------------------
Resolution: Won't Fix
I don't think we can really support truly heterogeneous capacity.
the problem is that each node's range is replicated to other nodes, so if you
have a single node w/ 2x more capacity than other nodes, you can't just give it
2x the range or its replicas will be swamped.
Moving to a dynamo-like system of multiple virtual nodes per machine might
allow this, but IMO the complexity is not worth it.
For long-lived clusters, I would recommend starting w/ relatively high end
machines, then keeping capacity (relatively) constant as cost decreases. So
heterogeneous in cost rather than capacity.
