Class ResourceProfile

java.lang.Object

org.apache.flink.runtime.clusterframework.types.ResourceProfile

All Implemented Interfaces:

Serializable, Comparable<ResourceProfile>

public class ResourceProfile
extends Object
implements Serializable, Comparable<ResourceProfile>

Describe the immutable resource profile of the slot, either when requiring or offering it. The profile can be checked whether it can match another profile's requirement, and furthermore we may calculate a matching score to decide which profile we should choose when we have lots of candidate slots. It should be generated from ResourceSpec with the input and output memory calculated in JobMaster.

Resource Profiles have a total ordering, defined by comparing these fields in sequence:

1. Memory Size
2. CPU cores
3. Extended resources

The extended resources are compared ordered by the resource names.
