Verifying the keyspace replication factor

Troubleshoot keyspace-related errors, such as incorrect replication, by checking whether a specific keyspace exists and whether the keyspace belongs to the correct data center.

• View the keyspace details by entering describe keyspace keyspace_name in the cqlsh console.

  Cassandra returns output similar to the following: CREATE KEYSPACE data WITH replication = {'class': 'NetworkTopologyStrategy', 'datacenter1': '3'} AND durable_writes = true; where:

  • class is the replication strategy.
  • datacenter1 is the name of the related data center. The data center name is associated with the current replication factor value, for example, 3.

• Configuring the replication factor

  Ensure reliability and fault tolerance by controlling how many data replicas you want to store across a Cassandra cluster.
