Your question is High-Performance Pipeline Architecture. 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).
Explain the architecture of a high-performance data pipeline you have built from scratch.
Describe the end-to-end design, including source ingestion, orchestration, transformation, storage, serving, data quality, failure recovery, and monitoring. Be prepared to justify your technology choices, explain how the pipeline achieved its performance objectives, and discuss trade-offs involving scalability, latency, cost, and maintainability.
