One of the most common scalability pitfalls in DynamoDB is unintentionally creating hot partitions.

These occur when one or more partition keys receive disproportionately high traffic compared to others, leading to throttled requests and performance bottlenecks.

However, AWS provides a built-in solution to help identify and debug this issue:
