Amazon DynamoDB now supports a CloudWatch Contributor Insights mode exclusively for throttled keys

DynamoDB now supports the ability to selectively emit events for throttled keys to CloudWatch Contributor Insights, enabling you to monitor throttled keys without emitting events for all accessed keys. By emitting events for throttled keys exclusively, you no longer need to pay for all of your successful request events.

Cloudwatch Contributor Insights for DynamoDB can help you understand your traffic patterns by providing information about your most accessed and throttled keys in a table or global secondary index. This information can be used to understand your application usage patterns or diagnose throttling-related issues. By choosing to only emit events for throttled keys, you can reduce the amount you spend to receive these insights.

The new mode to exclusively emit throttled key events to CloudWatch Contributor Insights is available in all commercial AWS Regions, the AWS GovCloud (US) Regions, and the China Regions.
