Query Caching Strategies

This walks you through multi-level caching with Redis, Memcached, and database-level strategies. You get patterns for cache invalidation (both event-based and time-based), TTL configuration, and cache warming on startup. The quick start shows a basic Redis implementation with PostgreSQL, and the reference guides cover specific database pairings plus LRU eviction strategies. Honestly, the value here is having the invalidation patterns laid out clearly, since that's usually where caching implementations get messy. Good fit if you're adding a cache layer to an existing system or trying to reduce database load on high-read workloads.
