✓ 应当这么做
- ✓ Give every key an explicit TTL and a documented invalidation owner
- ✓ Separate cache-aside reads from write-through paths deliberately
- ✓ Serialize cached values with a version prefix
✕ 常见反模式
- ✕ Caching mutable values without an invalidation trigger
- ✕ Using the cache as the only source of truth
- ✕ Unbounded key cardinality derived from raw user input
◎ 交付前验证
- ◎ Cache hit ratio re-measured after the change
- ◎ Cold-start behaviour produces correct results, not empty pages
- ◎ Stampede protection tested under concurrent misses
