Copy

public class HashPartitioner<T> : Configurable, 
	IPartitioner<T>

Public Class HashPartitioner(Of T)
	Inherits Configurable
	Implements IPartitioner(Of T)

generic<typename T>
public ref class HashPartitioner : public Configurable,

    class
        inherit Configurable
        interface IPartitioner<'T>
    end

Type Parameters

T: The type of the values to partition.

The HashPartitionerT type exposes the following members.

Properties

	Name	Description
	DfsConfiguration	Gets or sets the configuration used to access the Distributed File System. (Inherited from Configurable.)
	JetConfiguration	Gets or sets the configuration used to access the Jet servers. (Inherited from Configurable.)
	Partitions	Gets or sets the number of partitions.
	TaskContext	Gets or sets the configuration for the task attempt. (Inherited from Configurable.)

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetPartition	Gets the partition for the specified value.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyConfigurationChanged	Indicates the configuration has been changed. ApplyConfiguration(Object, DfsConfiguration, JetConfiguration, TaskContext) calls this method after setting the configuration. (Overrides ConfigurableNotifyConfigurationChanged.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

You can customize the behaviour of the HashPartitionerT by specifying a custom IEqualityComparerT. To do this, specify the type name of the custom comparer in the StageSettings of the stage that produces the records to be partitioned using the EqualityComparerSetting key.

If you don't specify a comparer, Default will be used.
