Sometimes I cache: implementing lock-free probabilistic caching

What this post added

Introduces a probabilistic cache revalidation strategy as an alternative to traditional cache locks. This involves simulating a die roll for each request to determine if it should go to the origin when the cache is stale, aiming to reduce origin load and prevent cache stampedes. The post details the implementation using Cloudflare Workers and the Cache API, and explores the mathematical expectancy of revalidation requests under different probabilities and request rates.
