Facebook Cache Invalidation Pipeline
Melita Mihaljevic, Facebook
“There are only two hard things in Computer Science: cache invalidation and naming things.”—Phil Karlton
Facebook serves 1.3 billion users across multiple regions. To make sure that all users have a consistent experience on the site, we built cache invalidation pipeline. This talk will cover cache invalidation pipeline for both caching solutions Memcache and TAO cross multiple regions. The talk will also touch a bit on how we monitor and debug cache consistency problems.
Melita Mihaljevic is a Production Engineer on the Global Consistency team at Facebook. The team is the first responder for keeping the cache consistent and for the health for Facebook's proprietary real-time data streaming infrastructure. They ensure that users have a consistent experience on the site across all their devices. Melita is actively developing and maintaining one of the cache invalidations pipeline services.
