Description

This control verifies if an Amazon DynamoDB table can automatically adjust its read and write capacity based on demand by using either on-demand capacity mode or provisioned mode with auto-scaling enabled.

By scaling capacity according to demand, the risk of throttling exceptions is reduced, supporting consistent application availability. Tables operating in on-demand capacity mode are restricted only by the default throughput quotas set by DynamoDB. To increase these quotas, you can submit a support ticket to AWS Support. DynamoDB tables using provisioned mode with auto-scaling dynamically adjust their provisioned throughput capacity based on traffic patterns.

Remediation

For guidance regarding enabling DynamoDB automatic scaling on existing tables, refer to the Enabling DynamoDB auto scaling on existing tables section of the Amazon DynamoDB Developer Guide.
