Set up cross-cluster replication for Aiven for OpenSearch® Limited availabilty

Set up cross-cluster replication (CCR) for your Aiven for OpenSearch service to ensure efficient data synchronization across different regions and cloud providers.


Cross cluster replication is not available for the Hobbyist and Startup plans.

Steps to set up CCR

  1. Log in to the Aiven Console, and select the Aiven for OpenSearch service for which to set up cross-cluster replication.

  2. In the service's Overview page, scroll to the Cross cluster replications section and click Create follower.

  3. In the Create OpenSearch follower cluster page:

    • Enter a name for the follower cluster.
    • Select the desired cloud provider.
    • Select the desired cloud region.
    • Select the service plan.

    During creation, the follower cluster service must have the same service plan as the leader cluster service. This ensures the follower cluster service has as much memory as the leader cluster. You can change the service plan as required later.

    • Add additional disk storage based on your business requirements
  4. Select Create.
