Subject Re: Reducing the number of vnodes

Which C* version are you running?
You might want to do an upgrade to the latest version before reducing the vnode counts, a
lot of fixes and improvement went in lately, it might help you getting your repair faster.

I’m thinking about reducing the number of vnodes per server.

We have 3 DC setup – one with 9 nodes, two with 3 nodes each.

Each node has 256 vnodes. We’ve found that repair operations are beginning to take too long.

Is reducing the number of vnodes to 64/32 likely to help our situation?
What options do I have for achieving this in a live cluster?
