Interview Prompt
Our users stream music on phones, desktop apps, smart speakers, and web browsers. We want to show artists and labels near-real-time stats on how their tracks are performing, and we need a historical record for royalty calculations. Design a data pipeline that collects listening events from all our device types.
Summary
Phones, tablets, laptops. And some of them report late.
