Class LocatableInputSplitList

java.lang.Object

org.apache.flink.runtime.jobmanager.splitassigner.LocatableInputSplitList

public final class LocatableInputSplitList
extends Object

The locatable input split list stores the locatable input splits for an input vertex that are still expected to be consumed. Besides simply storing the splits, the locatable input split list also computes the distance all Instance objects which request an input split and its nearest storage location with respect to the underlying network topology. That way input splits are always given to consuming vertices in a way that data locality is preserved as well as possible.

This class is not thread-safe.
