Your question is Real-Time Market Data Ingestion. 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).
Describe your approach to designing a real-time data ingestion pipeline for market ticks, including architecture, latency considerations, and fault tolerance.
Focus on how you would handle bursty tick volume, ordering, replay, schema evolution, and exactly-once or effectively-once delivery. Include how you would monitor end-to-end latency, data loss, and consumer lag.
