Cache-Aside
This topic shows why a familiar caching pattern still creates expensive surprises once miss cost, stale reads, and recovery behavior become real production concerns.
Layer
Understand the primitives
Build crisp intuition for the distributed systems primitives that shape real production tradeoffs.
Strong architectural judgment starts by understanding where guarantees weaken, where cost hides, and what abstractions are pretending to be simpler than they are.
Reading path
Start with primitives before pattern composition.
Start with the recommended topic in each pillar, then move outward into adjacent tradeoffs once the primitives are clear.

Teams adopt asynchronous flows quickly, then discover that duplicate delivery, retries, and partial failure demand far stricter reasoning.

Read Replica Staleness
This is a classic point where capacity wins can erase trust if consistency budgets are implicit.
