Excited to share the new feature that I was part of in sig-scheduling for #kubernetes v1.36, the Advanced Workload-Aware Scheduling! It introduced the PodGroup API and major restructure to the Workload API which are in v1alpha2 and the integration with Job Controller. kubernetes.io/blog/2026/05...

Kubernetes is changing one of the scheduler’s oldest assumptions: "Pod is always the right unit of scheduling". In this deep dive, we will walk through Workload-Aware Scheduling in Kubernetes, focusing on the API contract and the internals of gang scheduling. helayoty.substack.com/p/workload-a...
