Interface IAddressTranslator
Translates IP addresses received from Cassandra nodes into locally queryable addresses.
Namespace: Cassandra
Assembly: Cassandra.dll
Syntax
public interface IAddressTranslatorRemarks
The driver auto-detect new Cassandra nodes added to the cluster through server side
pushed notifications and through checking the system tables. For each node, the address
the driver will receive will correspond to the address set as rpc_address in the node
yaml file. In most case, this is the correct address to use by the driver and that is
what is used by default. However, sometimes the addresses received through this
mechanism will either not be reachable directly by the driver or should not be the
preferred address to use to reach the node (for instance, the rpc_address set on
Cassandra nodes might be a private IP, but some clients may have to use a public IP,
or pass by a router to reach that node). This interface allows to deal with such cases,
by allowing to translate an address as sent by a Cassandra node to another address
to be used by the driver for connection.
Please note that the contact points addresses provided while creating the
Cluster instance are not "translated", only IP address retrieve from or sent
by Cassandra nodes to the driver are.
Methods
Translate(IPEndPoint)
Translates a Cassandra rpc_address to another address if necessary.

a node has been configured to 0.0.0.0 server side, then the provided address will
be the node listen_address, not 0.0.0.0. Also note that the port for
