Class Summary
AbstractEndpointSnitch
AbstractNetworkTopologySnitch: An endpoint snitch tells Cassandra information about network topology that it can use to route requests more efficiently.
AbstractReplicationStrategy: A abstract parent for all replication strategies.
DynamicEndpointSnitch: A dynamic snitch that sorts endpoints by latency with an adapted phi failure detector
Ec2MultiRegionSnitch: 1) Snitch will automatically set the public IP by querying the AWS API 2) Snitch will set the private IP as a Gossip application state.
Ec2Snitch: A snitch that assumes an EC2 region is a DC and an EC2 availability_zone is a rack.

GossipingPropertyFileSnitch
LocalStrategy
NetworkTopologyStrategy: This Replication Strategy takes a property file that gives the intended replication factor in each datacenter.
OldNetworkTopologyStrategy: This Replication Strategy returns the nodes responsible for a given key but respects rack awareness.
PropertyFileSnitch: Used to determine if two IP's are in the same datacenter or on the same rack.
RackInferringSnitch: A simple endpoint snitch implementation that assumes datacenter and rack information is encoded in the 2nd and 3rd octets of the ip address, respectively.
SimpleSeedProvider
SimpleSnitch: A simple endpoint snitch implementation that treats Strategy order as proximity, allowing non-read-repaired reads to prefer a single endpoint, which improves cache locality.
SimpleStrategy: This class returns the nodes responsible for a given key but does not respect rack awareness.
