GossipingPropertyFileSnitch
This snitch is recommended for production. It uses rack and datacenter information for the local node defined in the cassandra-rackdc.properties file and propagates this information to other nodes via gossip.
The cassandra-rackdc.properties file defines the default datacenter and rack used by this snitch:
Note: datacenter and rack names are case-sensitive.
dc=DC1
rack=RAC1To save bandwidth, add the prefer_local=true option. This option tells Cassandra to use the local IP address when communication is not across different datacenters.
To allow migration from the PropertyFileSnitch, the GossipingPropertyFileSnitch uses the cassandra-topology.properties file when present.
