Scaling Real-Time Leaderboards with Dragonfly

This text discusses how to build a practical and realistic leaderboard system using Dragonfly, an efficient drop-in replacement for Redis. The implementation involves utilizing two of Dragonfly's data types - Sorted-Set and Hash - along with a SQL database (PostgreSQL) to create real-time, persistent leaderboards. These leaderboards include all-time, current-week, and previous weeks' leaderboards, providing valuable insights into user scores and performances. The text also covers the implementation of helper methods for consistent time calculations, management of Dragonfly keys, and key naming conventions.
