Choosing keyspace replication options
Options to set replication strategy.
To set the replication strategy for a keyspace, see CREATE KEYSPACE.
When you use NetworkToplogyStrategy
, during creation of the keyspace, you use
the datacenter names defined for the snitch
used by the cluster. To place replicas in the correct location, Cassandra requires a keyspace
definition that uses the snitch-configured datacenter names. For example, if the cluster uses
the PropertyFileSnitch, create the keyspace
using the user-defined datacenter and rack names in the
cassandra-topologies.properties file. If the cluster uses the Ec2Snitch, create the keyspace using EC2 datacenter
and rack names. If the cluster uses the GoogleCloudSnitch, create the keyspace using GoogleCloud datacenter and rack
names.
