Hi everyone,
๐ LWS v1.0.0 is released!ย ๐ Release notes ยท Installation and upgrades
Distributed inference APIs for Kubernetes, with LeaderWorkerSet and DisaggregatedSet.
โข ๐ Fractional rollout window: DisaggregatedSet roles advance proportionally, making better use of rollout budgets.
โข ๐ Scaling during rollouts: DisaggregatedSet scale-up continues during updates, with opt-in scale-down.
โข ๐งฉ Independently scalable sub-roles: Separate scaling and routing pools within a DisaggregatedSet role.
โข ๐ค Native gang scheduling reliability: Fixes for group recreation and resizing; still alpha and opt-in.
โข ๐ก๏ธ Bounded group recovery: Restart limits and backoff bound repeated group recreations.
โข โก Parallel Pod termination: Opt in to terminating leaders and workers together; sequential remains the default.
โข โ Stable configuration API: Controller configuration graduates to v1; v1alpha1 remains supported but deprecated.
