Cache made consistent: Meta’s cache invalidation solution

Caches help reduce latency, scale read-heavy workloads, and save cost. They are literally everywhere. Caches run on your phone and in your browser. For example, CDNs and DNS are essentially geo-replicated caches. It’s thanks to many caches working behind the scenes that you can read this blog post right now. Phil Karlton famously said, “There [...] Read More... The post Cache made consistent: Meta’s cache invalidation solution appeared first on Engineering at Meta.
