Answer
Use multi-layer caching including in-memory, Redis, CDN, and memoization. Apply TTL rules, stale-while-revalidate, and invalidation strategies.
Quick Answer
Advanced caching patterns: Cache-aside (app checks cache → miss → fetch from DB → store in cache), Write-through (write to cache and DB together), Write-behind (write to cache, async write to DB), Read-through (cache fetches from DB on miss automatically), Cache stampede prevention (probabilistic early expiration or locking). Match pattern to your read/write ratio.
