and hack the "LocalPartitioner" (because the local partitioner has been

Then the node you connect to and write is the node the data will get stored

Its like memcache "do it yourself" style sharding.
You'd have to use the ordered partitioner or something like that and

That said, are your nodes on a LAN? I have my 9+3 node cluster (two
