Interface Summary

Interface	Description
DynamicEndpointSnitchMBean
EndpointSnitchInfoMBean	MBean exposing standard Snitch info
IEndpointSnitch	This interface helps determine location of node in the datacenter relative to another node.
ReplicaCollection<C extends ReplicaCollection<C>>	A collection like class for Replica objects.
ReplicaCollection.Builder<C extends ReplicaCollection<C>>	A mutable (append-only) extension of a ReplicaCollection.
ReplicaLayout.ForRange
ReplicaLayout.ForToken
ReplicaPlan.Shared<E extends Endpoints<E>,P extends ReplicaPlan<E>>	Used by AbstractReadExecutor, {Data,Digest}Resolver and ReadRepair to share a ReplicaPlan whose 'contacts' replicas we progressively modify via various forms of speculation (initial speculation, rr-read and rr-write) The internal reference is not volatile, despite being shared between threads.
ReplicaPlans.Selector
SeedProvider

Class Summary

Class	Description
AbstractEndpointSnitch
AbstractNetworkTopologySnitch	An endpoint snitch tells Cassandra information about network topology that it can use to route requests more efficiently.
AbstractReplicaCollection<C extends AbstractReplicaCollection<C>>	A collection like class for Replica objects.
AbstractReplicaCollection.ReplicaList	A simple list with no comodification checks and immutability by default (only append permitted, and only one initial copy) this permits us to reduce the amount of garbage generated, by not wrapping iterators or unnecessarily copying and reduces the amount of indirection necessary, as well as ensuring monomorphic callsites
AbstractReplicaCollection.ReplicaMap<K>	A simple map that ensures the underlying list's iteration order is maintained, and can be shared with subLists (either produced via subList, or via filter that naturally produced a subList).
AbstractReplicationStrategy	A abstract parent for all replication strategies.
AlibabaCloudSnitch	A snitch that assumes an ECS region is a DC and an ECS availability_zone is a rack.
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.
Endpoints<E extends Endpoints<E>>	A collection of Endpoints for a given ring position.
EndpointsByRange
EndpointsByRange.Builder
EndpointsByReplica
EndpointsByReplica.Builder
EndpointsForRange	A ReplicaCollection where all Replica are required to cover a range that fully contains the range() defined in the builder().
EndpointsForRange.Builder
EndpointsForToken	A ReplicaCollection where all Replica are required to cover a range that fully contains the token() defined in the builder().
EndpointsForToken.Builder
EndpointSnitchInfo
GoogleCloudSnitch	A snitch that assumes an GCE region is a DC and an GCE availability_zone is a rack.
GossipingPropertyFileSnitch
InetAddressAndPort	A class to replace the usage of InetAddress to identify hosts in the cluster.
InetAddressAndPort.FwdFrmSerializer	Serializer for handling FWD_FRM message parameters.
InetAddressAndPort.Serializer	As of version 4.0 the endpoint description includes a port number as an unsigned short This serializer matches the 3.0 CompactEndpointSerializationHelper, encoding the number of address bytes in a single byte before the address itself.
InOurDcTester
LocalStrategy
NetworkTopologyStrategy	This Replication Strategy takes a property file that gives the intended replication factor in each datacenter.
PendingRangeMaps
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.
RangesAtEndpoint	A ReplicaCollection for Ranges occurring at an endpoint.
RangesAtEndpoint.Builder
RangesByEndpoint
RangesByEndpoint.Builder
ReconnectableSnitchHelper	Sidekick helper for snitches that want to reconnect from one IP addr for a node to another.
Replica	A Replica represents an owning node for a copy of a portion of the token ring.
ReplicaLayout<E extends Endpoints<E>>	The relevant replicas for an operation over a given range or token.

Replicas.ReplicaCount
ReplicationFactor
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.
SnitchProperties
SystemReplicas
TokenMetadata
TokenMetadata.Topology	Tracks the assignment of racks and endpoints in each datacenter for all the "normal" endpoints in this TokenMetadata.
TokenMetadataEvent	Events related to TokenMetadata changes.
