Redis Caching Patterns: Cache-Aside, Write-Through and the Stampede Problem
How common Redis caching patterns work, where they fail, and how to prevent cache stampedes, with runnable Python examples and reproducible simulations.

How common Redis caching patterns work, where they fail, and how to prevent cache stampedes, with runnable Python examples and reproducible simulations.

How each pattern moves data between your app, cache, and database, and how to pick the right one for your read/write mix.

Caching cut our response times, then introduced stale data, cache stampedes, invalidation bugs, and a database that struggled when Redis disappeared.

A practical, code-first guide to cache-aside, read-through, write-through, write-behind, and refresh-ahead caching, with Redis examples, eviction policies, and invalidation strategies.
