Interview Prompt
Our gaming platform generates hundreds of millions of player events per day across millions of concurrent sessions - matchmaking events, trophy unlocks, in-game purchases, and session telemetry. Different internal teams need this data at very different latencies and granularities. Design the event pipeline and justify where you use real-time streaming versus batch processing for each consumer.
Summary
Millions of gamers. The architecture decision changes everything.
