DynamoDB Global Tables Get Smarter: Detach Replicas Without Losing Data
Amazon DynamoDB global tables now let you disconnect replicas from multi-Region replication while keeping your data and table intact—perfect for stopping sync to specific regions or leaving shared multi-account setups. This works across all AWS Regions for tables using multi-Region eventual consistency, and you can manage it via Console, CLI, API, or CloudFormation.
