When AdmissionChecks or TopologyAwareScheduling were not configured, Admissions were mainly based on quota checks - if sufficient quota existed, Kueue admitted the Workload. While quota reservation confirmed logical resource availability, it didn’t guarantee that physical resources existed to schedule all Pods successfully. The ProvisioningRequest AdmissionCheck addresses this in cluster-autoscaler environments.

Kueue’s enhanced admission requires two sequential checks:

Quota Reservation: Kueue validates the resource requests against ClusterQueue’s available quota and resource flavors, reserves the required resources if available and locks the quota to prevent other Workloads from claiming it. This step verifies logical resource availability.
