  ElastiCache for Redis sorts and ranks datasets

  Real-time gaming leaderboards are easy to create with Amazon ElastiCache for Redis. Just use the Redis Sorted Set data structure, which provides uniqueness of elements while maintaining the list sorted by their scores. Creating a real-time ranked list is as simple as updating a user's score each time it changes. You can also use Sorted Sets to handle time series data by using timestamps as the score. https://aws.amazon.com/elasticache/redis/#:~:text=ElastiCache%20for%20Redis.-,Gaming,-Leaderboards
