Amazon DocumentDB (with MongoDB Compatibility) Global Clusters introduces Switchover

This article introduces a new capability for Amazon DocumentDB Global Clusters called Switchover, which allows seamlessly changing the primary AWS Region serving writes while preserving replication across all regions in the global cluster.

Specifically, the article covers:

• Amazon DocumentDB Global Clusters span up to 6 AWS Regions for disaster recovery and low-latency global reads
• Switchover synchronizes secondary clusters with the primary before changing the primary region, ensuring no data loss
• Use cases for Switchover include rotating the primary region for compliance or disaster recovery exercises
• Amazon DocumentDB simplifies operating highly available document workloads at scale without managing infrastructure
