Common Caching Patterns

Welcome! In this lesson, we'll explore common caching patterns. These patterns are structured ways your application interacts with a cache to improve performance and manage data.

Think of them as blueprints for how data flows between your application, the cache, and the main data store (like a database).

Cache-Aside (also known as Lazy Loading) is a very popular caching pattern. In this approach, your application is responsible for directly managing the cache.

• The application checks the cache first for data.
• If data is found (a "cache hit"), it's returned immediately.
• If data is not found (a "cache miss"), the application fetches it from the database, stores it in the cache, and then returns it.
