Your question is Real-Time Data Processing System. 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 that handles real-time data processing for mineral exploration.
Explain how you would ingest, validate, process, store, and serve continuously arriving exploration data. Address event ordering, late or duplicate records, schema evolution, replay and backfilling, fault tolerance, data quality, observability, and the trade-offs between latency, correctness, and cost. Include the technologies, data contracts, processing semantics, and operational strategy you would choose.
