Caching

Master caching strategies for distributed systems — cache layers, eviction policies, invalidation patterns, and the trade-offs that make or break system performance.

Cache Strategies

Master the core caching patterns — cache-aside, read-through, write-through, and write-behind. Understand when and why to use each strategy for low-latency, high-throughput systems.

Eviction & Invalidation

Master cache eviction policies (LRU, LFU, TTL), invalidation strategies, cache stampede prevention, and cache warming — the fundamentals of keeping caches fast and correct.

Failure Modes

Understand how caching systems fail in production — cache miss storms, cache penetration, and cache avalanche. Learn how to design systems that don't collapse under load.
