DynamoDB Global Tables

DynamoDB feature that replicates tables across multiple AWS regions as a multi-active (multi-writer) database.

Definition

Global tables replicate data automatically between replicas in chosen regions, allowing reads and writes in every region with typical replication within a second. Conflict resolution uses last-writer-wins; a multi-region strong consistency option is also available for selected configurations.

Example

A global chat app writes messages to the replica nearest each user via global tables.

Exam tip

Global tables are the answer for multi-region, active-active NoSQL with low-latency local writes.
