Cross-cluster replication for Aiven for OpenSearch® (limited availability)

Aiven for OpenSearch® now supports cross-cluster replication (CCR). This feature is in limited availability. Contact Aiven to request access.
CCR lets you replicate indices, mappings, and metadata from a leader cluster to one or more follower clusters across regions or cloud providers. Use it to place data closer to your users for lower query latency and to spread query-heavy workloads across follower clusters for better availability.
Set up CCR from the Cross cluster replication section on the service Overview page in the Aiven Console or with the Aiven API. You can promote an existing OpenSearch service to a follower or create a new one. This sets up the connection between the follower and the leader. Then you start replication from the follower using the OpenSearch replication APIs either per index or with an auto-follow rule that replicates every index matching a pattern. See Set up cross-cluster replication for Aiven for OpenSearch® for details.
