Set up {{ccr}} |
Use this guide to set up {{ccr}} (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.
::::{tip} If you want to replicate data across clusters in the cloud, you can configure remote clusters on {{ess}}. Then, you can search across clusters and set up {{ccr}}. ::::
