Amazon CloudWatch Contributor Insights for DynamoDB is now generally available. CloudWatch Contributor Insights for DynamoDB is a diagnostic tool that provides an at-a-glance view of your DynamoDB tables’ traffic trends and helps you identify your tables’ most frequently accessed keys (also known as hot keys). You can monitor each table’s item access patterns continuously and use CloudWatch Contributor Insights to generate graphs and visualizations of the table’s activity. Using this information, you can better understand the top drivers of your application’s traffic and respond appropriately to unsuccessful requests.
