Which move is the best default when caching becomes part of this workflow?
Multiple choiceMediumchapter-18-curatedpremiumarchitecturecaching
Answer and explanation
Correct answer
C. Add caching where measured read pressure justifies it and where stale data behavior is acceptable and explicit.
Why
Add caching where measured read pressure justifies it and where stale data behavior is acceptable and explicit. That is the stronger engineering move because candidates sound more senior when they mention invalidation and freshness openly. Blind caching can create correctness bugs that are harder to debug than the latency it was meant to solve.
