nodetool repair has some options that I don’t understand. Reading the 
documentation doesn’t exactly make things more clear. I’m running a 2.0.11 
cluster with vnodes and a single data center.

The docs say "Use -pr to repair only the first range returned by the 
partitioner”. What does this mean? Why would I only want to repair the first 
range?

What are the tradeoffs of a parallel versus serial repair?

What are the recommended options for regular, periodic repair?
 
Thanks

Robert
