DynamoDB – Global Tables

• Provide low-latency, multi-region access to DynamoDB data.

• Use Active-Active replication so applications can read and write from any region.

• Designed for global workloads requiring fault tolerance and high availability.

Key Points

• Replication is two-way and near real-time.

• DynamoDB Streams must be enabled.

• Each replica is a full read/write copy of the table.

• Reduces cross-region latency by serving requests locally.

Example

• Table in us-east-1 replicates to ap-southeast-2.

• Updates in either region are propagated automatically to the other.

Use Cases

• Global e-commerce platforms.

• Multi-region gaming backends.

• Applications with disaster recovery requirements.
