Your question is Consistency and Availability Tradeoff. 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).
Implement a system which has both consistency and availability in data. Why it is impossible?
Asked in the technical_round_3 stage. Explain the relevant distributed-systems tradeoff, then outline how you would implement and operate a practical data service when network partitions occur. Address what guarantees are possible, how clients observe failures or stale data, and how the design changes for read and write operations.
