Elastic: Replicate Elasticsearch Data with Cross-Cluster Replication (CCR)

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.

Highlights include:

• CCR overview and use cases
• Replicating Elasticsearch data without CCR
• Cross data center replication with CCR
• Getting started with CCR for logging use cases
