const ResourceAnnotationKeyResourceIdentifier = "katalyst.kubewharf.io/resource_identifier"

ResourceAnnotationKeyResourceIdentifier nominated the key to override the default name field in pod-resource-server (for qrm-related protocols); if the name field can't be guaranteed to be unique in some cases, we can relay on this annotation to get unique keys (to replace with the default name)

	ResourceNetBandwidth v1.ResourceName = "resource.katalyst.kubewharf.io/net_bandwidth"
)

const variables for resource names of guaranteed resource
