## Containers and BPF: twagent story Andrey Ignatov, Facebook eBPF Summit ## twagent • a daemon - runs on every Facebook server • manages all Facebook containers - a part of the bigger TW system

## A Multithreaded, Transaction-Based Locking Strategy for Containers Bob Steagall CppCon 2020 KEWB COMPUTING ## Overview • Sharing a container among multiple threads • A motivating problem • Some required • Every message input requires a write operation to the history • Which uses one or more containers ## Motivating Problem – Reactive Message Processor ![Image](/uploads/documents/9/0/0/c/900c7a required • Every message input requires a write operation to a container • Which uses one or more containers ## • It must scale to multiple threads! ## Motivating Problem – Reactive Message Processor !
