Your question is Data Consistency in Microservices. 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).
What strategies would you use to ensure data consistency in a distributed microservices architecture? Explain how you would handle transactions spanning services, retries, duplicate messages, partial failures, and conflicting updates. Discuss consistency requirements for online features, offline training data, model metadata, and observability, including the tradeoffs between strong consistency, eventual consistency, availability, and latency.
