Caching Strategies

Caching can dramatically improve performance and reduce costs, but it introduces staleness and invalidation complexity. You need a plan before you implement it.

Starting points

• HTTP caching (MDN)
• Redis basics
• Cache invalidation strategies

Points of attention

• The data that can be cached and its duration are defined, along with a clear invalidation strategy.
• Idempotency and retries for cache misses and evictions are addressed.
• A plan is in place to measure the cache hit ratio and its impact.
