Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static enum	TaskDeploymentDescriptorFactory.PartitionLocationConstraint	Defines whether the partition's location must be known at deployment time or can be unknown and, therefore, updated later.
static class	TaskDeploymentDescriptorFactory.ShuffleDescriptorAndIndex	This class represents the shuffle descriptor with it index in ConsumedPartitionGroup.
static class	TaskDeploymentDescriptorFactory.ShuffleDescriptorGroup	A set of shuffle descriptors that will be serialized together.

OFFLOAD_SHUFFLE_DESCRIPTORS_THRESHOLD

@Experimental
public static final org.apache.flink.configuration.ConfigOption<Integer> OFFLOAD_SHUFFLE_DESCRIPTORS_THRESHOLD

This is an expert option, that we do not want to expose in the documentation. The default value is good enough for almost all cases
