Exercise Steps
1

Setup Redis and Application Environment

Current

Create a Docker Compose environment with Redis, Redis Commander for visualization, and a Node.js application.

2

Implement Cache-Aside Pattern

Build the most common caching pattern where the application checks cache first, then falls back to the database.

3

Implement Write-Through Caching

Build a write-through cache where writes go to both cache and database simultaneously.

4

Advanced Cache Invalidation Strategies

Implement multiple cache invalidation patterns including TTL-based, event-based, and tag-based invalidation.

5

Leverage Redis Data Structures

Use Redis Lists, Sets, Sorted Sets, and Hashes for advanced caching scenarios.

6

Monitor and Optimize Cache Performance

Implement monitoring, analyze cache metrics, and optimize for production.
