Caching Roadmap

What is caching? Why is it used?

Trade-offs of caching (latency vs. consistency)

Different types of caches (content, page, data, query, etc.)

Server-side vs client-side caching

Least Recently Used (LRU), Least Frequently Used (LFU), Least Recently Updated (LRU), Time-To-Live (TTL), Random Replacement (RR) eviction policies

In-process, inter-process, remote inference caching

Cache expiration strategies (time-based, data-driven)

Cache coherence

Cache synchronization and write policies (write-through, write-around, write-back)

Introduction to Distributed Caching

Cache consistency in distributed systems

Distributed lock mechanisms

Cache partitioning and replication

Fault tolerance and availability
