Verifying the keyspace replication factor
Version:
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.
