Topic
A familiar pattern that becomes operationally expensive when the miss path is weak.
Cache-aside works well only when the miss path is survivable, freshness is explicit, and invalidation ownership is clear.
Prerequisites
Why this topic matters
This topic shows why a familiar caching pattern still creates expensive surprises once miss cost, stale reads, and recovery behavior become real production concerns.
Primary article
