(GKE only) Configure replicationType

If you are using a GKE cluster, you must pay attention to the cassandra object's storage.gcepd.replicationType property. If you set up a Zonal location, the replicationType must be none. If you set up a Regional location (recommended), the value must be regional-pd.

To configure replication:

  1. Open the overrides.yaml file for edit if it is not already open.
  2. If you set up your GKE cluster to have a Regional location (recommended), set the cassandra object's storage.gcepd.replicationType property to regional-pd. Otherwise, set it to none:

    For example:

    namespace: MyNamespace
    config:
    
      base64Credentials: dXNlckBleGFtcGxlLmNvbTphYmMxMjM=
      envs:
        - orgName: MyOrganization
          envName: MyEnvironment
    
    cassandra:
      storage:
        type: gcepd
        capacity: 50Gi
        gcepd:
          ## Set replicationType to 'none' if using a Zonal GKE
          replicationType: regional-pd
    ...

    For more information, see Set up a GKE cluster.

  3. Save your changes to the override.yaml file.
