If you're going to always ever hit one node, then using a token aware client is over-complicating it. Just use a one node cluster and you'll have nothing to worry about or to configure. That being said, Colin, do be aware that as far as I can tell there is indeed relatively little benefit to having a multi-node cluster on which all data is on one node (in particular, there is no cache at the coordinator level, so that even if your client hit other nodes, everything will still be forwarded to the one node that stores it all, the other nodes won't store anything really, not even in memory). -- Sylvain
