There are n vnodes regardless of the size of the physical cluster.

Since Cassandra's vnodes don't work like for example Riak's, where there is a fixed number of vnodes distributed evenly over the nodes, why so many? Even with a moderately sized cluster you get thousands of slices. Does this matter? If your cluster grows to over thirty machines and you start looking at ten thousand slices, would that be a problem? I guess trat traversing a list of a thousand or ten thousand slices to find where a token lives isn't a huge problem, but are there any other up or downsides to having a small or large number of vnodes per node?I understand the benefits for splitting up the ring into pieces, for example to be able to stream data from more nodes when bootstrapping a new one, but that works even if each node only has say 32 vnodes (unless your cluster is truly huge).yours,Theo
