Reference documentation and code samples for the Google Cloud Dataproc v1 API class InstanceFlexibilityPolicy.Types.InstanceSelection.
Defines machines types and a rank to which the machines types belong.
Optional. Preference of this instance selection. Lower number means
higher preference. Dataproc will first try to create a VM based on the
machine-type with priority rank and fallback to next rank based on
availability. Machine types and instance selections with the same
priority have the same preference.
