Problem

We run a short-video platform where roughly 5 billion engagement events a day (views, likes, watch-time pings) come off the apps. The trending team needs the hottest videos surfaced within seconds of a spike, while the growth team reports daily active users and 7-day retention on a T+1 cadence from the same events. Design the pipeline that serves both consumers without paying to stream everything.
