We run a large online gaming platform with tens of millions of active players. The product team wants a real-time leaderboard showing top players by score, a live matchmaking dashboard, and post-game session analytics for the data science team. We currently batch-process all game events daily. Design the analytics pipeline and justify your architecture decisions.
