Architecture · interview question
What is the clearest sign that code around idempotency should be refactored?
Multiple choiceMediumchapter-18-curatedpremiumarchitectureidempotency
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. Design jobs so a duplicate message or retry does not produce duplicate side effects.
