> CASSANDRA-930 made read repair "fuzzy optional," but this only helps with ConsistencyLevel.ONE:
> - Quorum reads always send requests to all nodes
> - only the first Quorum's worth of responses get compared
> So what we'd like to do two changes:
> - only send read requests to the closest R live nodes
> - if read repair is enabled, also compare results from the other nodes in the background
