Redis
Redis is an in-memory data store used for caching, session management, real-time features, and as a message broker for queues.
Why It Matters
Redis dramatically speeds up applications by storing frequently accessed data in memory rather than querying the database repeatedly.
When to Use This
- Caching database queries to reduce load
- Managing user sessions across multiple servers
- Real-time features like live notifications
- Queue jobs for background processing
- Rate limiting API requests
Examples
- Caching the首页 to serve 10,000 requests per second
- Storing session data so users stay logged in across servers
- Real-time chat using Redis pub/sub
- Job queue processing with Laravel and Redis
