A recent article provides a detailed guide on implementing cross datacenter replication (XDCR) in Couchbase, highlighting its benefits for disaster recovery and data locality. It covers the entire process from setting up clusters to replicating NoSQL documents between clusters. The configuration is noted for its simplicity, with a step-by-step video demonstrating the process using Docker containers for ease of demonstration on a local machine. While Docker is used in the demonstration, the article notes that in production environments, various options are available, from AWS to bare metal. For additional information, readers are directed to the Couchbase Developer Portal.
