Evolving Cluster Management
summary
Meta replaces ad hoc per-task tweaks with a new stateful control service called the Twine job control plane that accepts high-level intents from Conveyor and autoscaling systems and reconciles them into task plans. The rewrite eliminates freeform task customization, cuts conflict between pushes and canaries, handles a 10-fold rise in job churn, already manages over 95% of services and enabled a scheduler feature that saved about 30% of GPU capacity for inference.
