Jonathan Ellis commented on CASSANDRA-1519:
-------------------------------------------
after a closer look at the DES code I don't think it matches what the comments
in the config file say. I think we need to actually pull the subsnitch value
out so we know which one it's supposed to have affinity to, then see if the
affinity'd score is over threshold larger than the other, and if so, override
it.

> with CASSANDRA-1314, we'd like to have dynamic snitch route around
> slow/failing nodes but not messing with our "pinning" of ranges to nodes
> unless a threshold of badness is crossed. (Threshold should be optional
> since other snitches pure dynamic corresponds exactly to what we want.)
