Modifying and tuning ZooKeeper… Continue reading Introducing Zelos: A ZooKeeper API leveraging Delos

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… Continue reading Cache made consistent: Meta’s cache invalidation solution
