This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

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:

  • Geo-proximity so that reads can be served locally
