Your question is Real-Time Data Processing Design. 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).
Design a system for real-time data processing. What components would you include?
Describe a production-ready architecture from event producers through ingestion, processing, storage, and downstream serving. Explain technology choices, delivery semantics, partitioning, schema management, data quality, observability, failure recovery, and how the design would scale. Include representative implementation details and discuss trade-offs between latency, consistency, durability, and operational complexity.
