DynamoDB global tables, which provide multi-Region and multi-master replication, now allow the disassociation of a replica while preserving its table and data. This capability enables users to stop cross-Region replication and continue using the table independently in a single Region without the need to recreate or copy data.
The feature supports both same-account and multi-account global tables employing multi-Region eventual consistency and is available across all AWS Regions. This enhancement simplifies management of distributed applications by providing granular control over replication and reducing operational efforts associated with replica maintenance.
