Cache Invalidation Hell — The Second Hardest Problem in Computer Science
Users see stale prices. Admins update settings but the old value is served for 10 minutes. You delete a record but it keeps appearing. Cache invalidation is famously hard — and most implementations have subtle bugs that serve wrong data long after the source changed.

Cache Stampede — When Your Cache Fix Breaks Everything
Cache stampede (a.k.a. thundering herd on TTL expiry) is one of the most dangerous failure modes in high-traffic systems. The moment your cache key expires, hundreds of simultaneous requests hammer your database — often killing it. Here''s how it happens, and exactly how to fix it.

Inconsistent Reads — The Eventual Consistency Shock
User updates their profile. Refreshes the page — old data shows. They update again. Still old data. They''re furious. Your system is eventually consistent — but nobody told the user (or the developer who designed the UI). Here''s how to manage consistency expectations in distributed systems.

Redis Eviction Causing Chaos — When Your Cache Turns on You
Redis is full. Instead of failing gracefully, it starts silently evicting your most important cache keys — session tokens, rate limit counters, distributed locks. Your app behaves mysteriously until you realize Redis has been quietly deleting data. Here''s how to tame Redis eviction.
