CloudFront enhanced cache management by adding support for invalidating cached objects by user-defined tags rather than solely by URL paths. This enables targeted invalidation of related content sets, improving operational workflows such as coordinated updates, takedown requests, and content compliance across distributed edge caches.
Developers tag cached objects via HTTP response headers, then issue single invalidation requests specifying tags to remove all associated objects simultaneously. This approach reduces unnecessary cache clearing, preserves high cache-hit ratios, and achieves near real-time content freshness—propagating invalidations under 5 seconds (P95) with status feedback under 25 seconds (P95). This feature is broadly available except in China regions.
