Your question is Design High-Throughput Event Pipeline. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You're designing a real-time event pipeline for a product that emits a very large volume of telemetry. The system needs to support continuous ingestion, low-latency processing, and downstream consumption by analytics and detection systems.
Design a data pipeline that processes millions of events per second with sub-second latency.
