"The key advantage of vnodes in this case is that you do not need to manually rebalance the cluster when adding or removing nodes."
Well, I thing that a bigger "key advantage" of vnodes would rather be the performance improvement due to the evenly distributed load while streaming data. But it indeed simplify cluster balancing even if you have an heterogeneous cluster with different hardware for each node. Anyways, this is well described here: http://www.datastax.com/dev/blog/virtual-nodes-in-cassandra-1-2 Alain 2013/1/10 Sam Overton <s...@acunu.com> > The key advantage of vnodes in this case is that you do not need to > manually rebalance the cluster when adding or removing nodes. >
