Given the issue with repairs and Vnodes (currently expected to be fixed with the 3.0 release) I am considering reducing the number of tokens per node. One of my clusters has 8 nodes in it with 256 tokens per node. The main keyspace on it has 40+ column families and nodetool repair takes extremely long to complete on that keyspace.
I have two questions with respect to this 1) Is there a way/formula to determine an appropriate number of tokens per node. I am considering going as low as 32 or even 16 tokens per node. 2) What is the recommended procedure for reducing the number of Vnodes? Do I just reduce it in the cassandra.yaml and start removing tokens via nodetool? Rahul Neelakantan
