caching-and-performance

Configure Cache-Control headers by setting s-maxage for CDN caching TTL and max-age for browser TTL. This ensures effective API caching at the edge, reducing server load and improving response times. You can also add stale-while-revalidate to improve perceived performance.

Implement API resilience patterns like circuit breakers and connection pooling to prevent cascading failures. These strategies maintain system stability by failing fast and reusing existing connections, ensuring high throughput during traffic spikes.

Brotli compression and gzip both optimize HTTP API response data transfer. Brotli generally achieves higher compression ratios, while gzip offers broader compatibility. Utilizing either protocol strategy reduces latency and improves API speed.

You need ETags and conditional requests for HTTP caching when validating resource freshness without transferring full payloads. This mechanism conserves bandwidth and reduces server load by returning 304 Not Modified responses for unchanged API resources.

HTTP/2 and HTTP/3 adoption improves API throughput and low latency through multiplexing and reduced connection overhead. Upgrading to these protocols ensures efficient data transfer and optimized network resource usage for high-performance APIs.
