Why we're rethinking cache for the AI era

What this post added

This post introduces the concept of rethinking web cache design for the AI era, driven by the observation that AI traffic (crawlers, assistants) exhibits different patterns than human traffic. It details how AI traffic, characterized by high unique URL ratios, content diversity, and crawling inefficiency, leads to increased cache miss rates and churns existing caches. The post proposes AI-aware caching strategies, differentiating between AI applications requiring low latency and content collection jobs that can tolerate higher latency, suggesting the use of different cache tiers or admission control mechanisms.
