✓ 应当这么做
- ✓ Name the invalidation owner for every cache entry
- ✓ Version cache keys so a deploy can invalidate without a purge
- ✓ Protect against stampedes with single-flight or jittered expiry
✕ 常见反模式
- ✕ Caching data whose correctness depends on user-specific authorisation without scoping the key
- ✕ Infinite TTLs with no owner
- ✕ Treating the cache as durable storage
◎ 交付前验证
- ◎ Row counts and key uniqueness compared against the previous run
- ◎ Backfill path tested on a partition
- ◎ Lineage graph updated for the new source
