Architecture · interview question
A teammate submits shaky caching code. Which review comment is the strongest?
Multiple choiceMediumchapter-18-curatedpremiumarchitecturecaching
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Add caching where measured read pressure justifies it and where stale data behavior is acceptable and explicit.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Blind caching can create correctness bugs that are harder to debug than the latency it was meant to solve.
