[v0.1.1] - 2026-07-26

Added

  • kai.scheduler/v1 API group (kai/v1): Config and SchedulingShard types plus their component sub-packages, with generated CRD manifests. usagedb config structs (UsageDBConfig, UsageParams, WindowType), podgrouper/constants, and utilities/math (SaturatingAdd).

Changed

  • Re-synced utilities/resources (DRA GPU-count overflow fix), scheduling/v2alpha2 PodGroup types, and podgrouper/constants with KAI-Scheduler main.

v0.1.0

Initial release of the standalone github.com/kai-scheduler/api module, seeded from KAI-Scheduler main.

Added

  • API types (client-backed CRD contracts):

    • Queue (scheduling.run.ai/v2) — hierarchical queue resource
    • PodGroup (scheduling.run.ai/v2alpha2) — gang scheduling with subgroups, plus validating webhook
    • BindRequest, NumaPlacementRequest (scheduling.run.ai/v1alpha2) — pod binding coordination
    • Topology (kai.scheduler/v1alpha1) — topology-aware scheduling input

  • Generated clients — single clientset, informer factory, and listers spanning both the scheduling.run.ai and kai.scheduler/v1alpha1 groups.

  • CRD manifests (config/crd/):

    • scheduling.run.ai_queues.yaml
    • scheduling.run.ai_podgroups.yaml
    • scheduling.run.ai_bindrequests.yaml
    • kai.scheduler_topologies.yaml

  • Utilities:

    • utilities/resources/ — GPU fraction/memory extraction, DRA support, resource list operations
    • utilities/podgroup/ — CalculatePreemptibility()

  • Constants — GPU annotation keys, labels, and priority constants.

  • Code generation — make generate (deepcopy), make manifests (CRDs), make clients (clientset/informers/listers) reproduce all generated artifacts.

Notes

  • Seeded fresh from main (no git history preserved); Apache 2.0 / NVIDIA attribution retained via per-file headers.
  • Scheduler-internal code stays in kai-scheduler: kai.scheduler/v1 config types (Config, SchedulingShard), scheduler-framework glue (k8s_utils), and feature gates.
  • Dependencies: Kubernetes v0.35.4, controller-runtime v0.23.3, Go 1.26.3.
