Explanation

The ProvisionedThroughputExceededException error in DynamoDB occurs when your application exceeds the provisioned read or write capacity for a specific partition. In this case, the partition key is the country of the player, and it appears that a sudden increase in the number of players from a specific country is causing the partition to become "hot," meaning that the requests for that partition are exceeding the available throughput. To resolve this issue, the developer should consider revising the primary key to spread the load more evenly across partitions. Using more unique identifiers for the partition key, such as adding an additional attribute (e.g., player ID, country + player ID, or a timestamp) can help distribute the data more evenly, preventing any single partition from becoming a hotspot.
