Caching Strategies
Improve response times and reduce infrastructure load without data correctness regressions.
Recommended approach
- Cache read-heavy, low-volatility queries.
- Use explicit TTLs and invalidation strategies per domain.
- Prefer cache-aside patterns for most API workloads.
Alternatives and when to choose them
- Write-through caching when consistency requirements are high.
- No cache when data freshness and simplicity outweigh latency gains.
Implementation checklist
- Define cache key format and namespace ownership.
- Track hit ratio and stale/error rates.
- Add invalidation hooks for mutable resources.
Common pitfalls
- Global default TTLs with no domain reasoning.
- Caching authorization-sensitive data without scoping keys.
