Enum LocationPreferenceConstraint

java.lang.Object

java.lang.Enum<LocationPreferenceConstraint>

org.apache.flink.runtime.jobmanager.scheduler.LocationPreferenceConstraint

All Implemented Interfaces:

Serializable, Comparable<LocationPreferenceConstraint>

public enum LocationPreferenceConstraint
extends Enum<LocationPreferenceConstraint>

Defines the location preference constraint.

Currently, we support that all input locations have to be taken into consideration and only those which are known at scheduling time. Note that if all input locations are considered, then the scheduling operation can potentially take a while until all inputs have locations assigned.
