Automatically updates all nodes using gossip when adding new nodes.
The GossipingPropertyFileSnitch defines a local node's data center and rack; it uses gossip for propagating this information to other nodes.
dc=DC1 rack=RAC1The location of the conf directory depends on the type of installation:
- Packaged installs: /etc/cassandra/conf/cassandra-rackdc.properties
- Tarball installs: install_location/conf/cassandra-rackdc.properties
To migrate from the PropertyFileSnitch to the GossipingPropertyFileSnitch, update one node at a time to allow gossip time to propagate. The PropertyFileSnitch is used as a fallback when cassandra-topologies.properties is present.
