Launched in Elasticsearch version 6.5, 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, data locality (multiple copies of data closer to users), and creating a dedicated, centralized analytics cluster populated by multiple source clusters.
