Question
A video game company has a platform that provides 20 video games to users around the world. The company's development team uses an Amazon DynamoDB table as the database to store user information for the platform. The table uses an attribute named GameTitle as the partition key and an attribute named UserId as the sort key. The development team notices that requests to the table are being throttled. The development team receives ProvisionedThroughputExceededException errors. The development team must resolve the throttling issue. Which solution will meet this requirement?

Explanation

By switching the partition key to UserId, the workload is more evenly distributed across partitions, since UserId is more likely to be unique and diverse, reducing throttling and improving
