An worldwide gaming company's development team is experimenting with using Amazon DynamoDB to
store in-game events for three mobile titles. Maximum concurrent users for the most popular game is 500,000, while the least popular game is 10,000. The typical event is 20 KB in size, while the average user

unique identification.
The lead developer generated a single DynamoDB database with the following structure for the events:
Partition key: game name
Sort key: event identifier
Local secondary index: player identifier
