A gaming company is building a mobile game that will have as many as 25,000 active concurrent users in the first 2 weeks after launch. The game has a leaderboard that shows the 10 highest scoring players over the last 24 hours. The leaderboard calculations are processed by an AWS Lambda function, which takes about 10 seconds. The company wants the data on the leaderboard to be no more than 1 minute old.
Which architecture will meet these requirements in the MOST operationally efficient way?

A. Deliver the player data to an Amazon Timestream database. Create an Amazon ElastiCache for Redis cluster. Configure the Lambda function to store the results in Redis. Create a scheduled event with Amazon EventBridge to invoke the Lambda function once every minute. Reconfigure the game server to query the Redis cluster for the leaderboard data.

B. Deliver the player data to an Amazon Timestream database. Create an Amazon DynamoDB table. Configure the Lambda function to store the results in DynamoDCreate a scheduled event with Amazon EventBridge to invoke the Lambda function once every minute. Reconfigure the game server to query the DynamoDB table for the leaderboard data.

C. Deliver the player data to an Amazon Aurora MySQL database. Create an Amazon DynamoDB table. Configure the Lambda function to store the results in MySQL. Create a scheduled event with Amazon EventBridge to invoke the Lambda function once every minute. Reconfigure the game server to query the DynamoDB table for the leaderboard data.

D. Deliver the player data to an Amazon Neptune database. Create an Amazon ElastiCache for Redis cluster. Configure the Lambda function to store the results in Redis. Create a scheduled event with Amazon EventBridge to invoke the Lambda function once every minute. Reconfigure the game server to query the Redis cluster for the leaderboard data.
