API Caching Documentation 📚

What is API Caching?

Caching is a technique to store frequently accessed data temporarily to improve performance and reduce load on backend systems. By caching responses, you can significantly speed up subsequent requests and lower resource consumption.

Key Benefits ✅

• Faster Response Times
• Reduced Server Load
• Lower Bandwidth Usage
• Improved User Experience

How Caching Works 🔄

1. Request Check
   • The server checks if the requested data is already in the cache.
2. Cache Hit
   • If data exists, it is returned directly from the cache (🟢).
3. Cache Miss
   • If data is not found, it is fetched from the backend and stored in the cache (🟠).

Best Practices 📝

• Use TTL (Time-to-Live) to manage cache expiration.
• Implement cache invalidation strategies for dynamic data.
• Combine caching with compression for larger payloads.
• Monitor cache hit/miss ratios to optimize performance.

Use Cases 🌐

• Read-heavy APIs (e.g., fetching user profiles)
• Frequently accessed endpoints (e.g., /api/v1/products)
• Static content delivery (e.g., images, documentation)
