advancedReal System Design Problems
Design a Content Management System (CMS) — versioning, drafts, and publish workflows at scale.
The read-heavy content delivery problem: content versioning, draft-vs-published state management, and how content is cached when it must be invalidated the instant something is published. The cache invalidation strategy on publish — pushing a fresh version out to every edge/cache layer without serving a stale draft — is the most interesting part.
