Cross-cluster replicationedit

The cross-cluster replication (CCR) feature enables replication of indices in remote clusters to a local cluster. This functionality can be used in some common production use cases:

  • Disaster recovery in case a primary cluster fails. A secondary cluster can serve as a hot backup
  • Geo-proximity so that reads can be served locally
  • Prevent search load from interfering with indexing by offloading search to a secondary cluster

This guide provides an overview of cross-cluster replication:
