Today, we released the Amazon DynamoDB key diagnostics library, which provides near-real-time key usage information for DynamoDB. This library is a lightweight, client-side utility that can help you to analyze your table's traffic and display visualizations that show the number of reads and writes to each partition key. By using the library, you can adjust to unpredictable and uneven workloads in near-real time. To learn more about the library, how to set it up, and to identify hot keys, see How to use the new Amazon DynamoDB key diagnostics library to visualize and understand your application’s traffic patterns.
