Tutorial: Set up cross-cluster replication
editUse this guide to set up cross-cluster replication (CCR) between clusters in two datacenters. Replicating your data across datacenters provides several benefits:
- Brings data closer to your users or application server to reduce latency and response time
- Provides your mission-critical applications with the tolerance to withstand datacenter or region outages
In this guide, you’ll learn how to:
- Configure a remote cluster with a leader index
- Create a follower index on a local cluster
- Create an auto-follow pattern to automatically follow time series indices that are periodically created in a remote cluster
You can manually create follower indices to replicate specific indices on a remote cluster, or configure auto-follow patterns to replicate rolling time series indices.
If you want to replicate data across clusters in the cloud, you can configure remote clusters on Elasticsearch Service. Then, you can search across clusters and set up cross-cluster replication.
