Memory footprint

Quick question about Riak's memory footprint: I know that Bitcask
requires all keys to fit in memory.  Does this mean only the keys that
reside on a given node, or does each node hold the keys of the entire
system?  I assume it's the former, but I just want to be sure.

Basically what I'm trying to figure out is whether we should expect
better performance from a cluster of N nodes with 2*M GB of memory
each, or 2*N nodes with M GB each.

Thanks!
