Class Summary
Class | Description
--- | ---
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.
CloudstackSnitch | A snitch that assumes a Cloudstack Zone follows the typical convention <country>-<location>-<availability zone> and uses the country/location tuple as a datacenter and the availability zone as a rack
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.
EndpointSnitchInfo |
GoogleCloudSnitch | A snitch that assumes an GCE region is a DC and an GCE 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.
ReconnectableSnitchHelper | Sidekick helper for snitches that want to reconnect from one IP addr for a node to another.
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.

TokenMetadata |
TokenMetadata.Topology | Tracks the assignment of racks and endpoints in each datacenter for all the "normal" endpoints in this TokenMetadata.
YamlFileNetworkTopologySnitch | Network topology snitch that reads its configuration from a YAML file.
YamlFileNetworkTopologySnitch.Datacenter | Data center object type for the YAML topology configuration.
YamlFileNetworkTopologySnitch.Node | Node object type for the YAML topology configuration.
YamlFileNetworkTopologySnitch.Rack | Rack object type for the YAML topology configuration.
YamlFileNetworkTopologySnitch.TopologyConfig | Root object type for the YAML topology configuration.
