System Design: Types of cache
Master the real-world cache strategies used in system design interviews and high-scale systems.
In this video, we go beyond basic caching concepts and dive into production-level techniques that solve real problems like cache stampede, stale data, and traffic spikes.
🚀 What you’ll learn:
TTL + Jitter (Randomization)
Prevent cache stampede by avoiding simultaneous expirations.
Mutex / Distributed Locking (using tools like Redis)
Ensure only one request rebuilds the cache while others wait.
Cache Warming
Preload critical data before users request it to reduce cold starts.
Stale-While-Revalidate
Serve old data instantly while refreshing cache in the background.
