Architecture · interview question
What is the clearest sign that code around caching should be refactored?
Multiple choiceMediumchapter-18-curatedpremiumarchitecturecaching
Answer and explanation
Correct answer
B. When the rule is no longer easy to trace, explain, or change without breaking nearby behavior.
Why
A refactor is justified when the code stops communicating its intent. Add caching where measured read pressure justifies it and where stale data behavior is acceptable and explicit.
