How Facebook Scaled Memcached

· 7 min · Season 1 Episode 11

Show notes

In this episode, we explore how Facebook engineers scaled Memcached, the open-source caching system, to handle billions of requests and trillions of items. We’ll break down the challenges they faced and the smart solutions they developed — from reducing latency to optimizing memory usage. Join us as we uncover how they transitioned from a single cluster to a distributed system spread across the globe, tackling data replication, load balancing, and more. If you’re curious about the inner workings of high-performance caching at massive scale, this one’s for you.
