Kubernetes v1.37: Advancing Workload-Aware Scheduling
Kubernetes v1.37 graduates the core Workload and PodGroup APIs, which enable gang scheduling, to Beta, along with workload-aware preemption and shared DRA ResourceClaims for PodGroups. The release adds a CompositePodGroup API for multi-level hierarchical scheduling, and makes minCount mutable so controllers can resize gangs. The alpha v1alpha2 API was replaced by v1alpha3, and the disruptionMode values were renamed from PodGroup and Pod to all and single.
What changes for platform teams
Platform teams running batch or AI/ML workloads on Kubernetes should plan for the v1alpha2 to v1alpha3 breaking change and the disruptionMode rename if they use the alpha APIs. Teams can also begin evaluating native gang scheduling and hierarchical scheduling for JobSet and LeaderWorkerSet workloads.
