Jeremy Hanna commented on CASSANDRA-11488:
------------------------------------------
Giving this some more though, I think we need to document the distinction. I
didn't realize that the dynamic snitch would route away from local nodes when
using TokenAware load balancing for example. It does make sense if that local
node is really behind on LCS or has some heavier operation going on. I just
don't think people expect TokenAware would get routed to another replica
necessarily.
In any case I agree that documentation is probably the best outcome for now
unless there is data that shows that this is insufficient.
> Bug or not?: coordinator using SimpleSnitch may query other nodes for copies
> of local data
