snitch that prefers a single replica for all reads to a given key
-----------------------------------------------------------------
Key: CASSANDRA-1314
URL: https://issues.apache.org/jira/browse/CASSANDRA-1314
Project: Cassandra
Issue Type: New Feature
Components: Core
Reporter: Jonathan Ellis
Assignee: Jonathan Ellis
Priority: Minor
Fix For: 0.7 beta 1
motivation is, if you reduce or eliminate read repair (CASSANDRA-930) then you
can cache about RF times as much data in memory, than if you're scattering
reads across all the replicas equally.
making this data-center aware would be a nice improvement, but i'm just
targetting a single DC here.
