Implementing Basic Cache Patterns

Welcome! In this lesson, we'll dive into two fundamental caching patterns: Cache-Aside and Write-Through. These patterns help you integrate Redis into your applications to store and retrieve data efficiently.

Understanding them is key to building responsive and scalable systems.

The Cache-Aside pattern is one of the most common ways to use a cache. Here, your application is responsible for managing both the cache and the primary data store (like a database).

• When reading data, the app first checks the cache.
• If found (a 'cache hit'), it returns the cached data.
• If not found (a 'cache miss'), it fetches the data from the database, stores it in the cache, and then returns it.
