Launched in Elasticsearch version 6.7, cross-cluster replication (CCR) allows you to replicate an index from one Elasticsearch cluster to another. CCR is perfect for a number of use cases, including cross data center replication for high availability or disaster recovery, data locality (keeping copies of data closer to users), and creating a dedicated, centralized analytics cluster populated by multiple source clusters.
