Class Merge

java.lang.Object

software.amazon.awssdk.services.glue.model.Merge

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<Merge.Builder,Merge>

@Generated("software.amazon.awssdk:codegen")
public final class Merge
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Merge.Builder,Merge>

Specifies a transform that merges a DynamicFrame with a staging DynamicFrame based on the specified primary keys to identify records. Duplicate records (records with the same primary keys) are not de-duplicated.

Method Detail

name

public final String name()

The name of the transform node.

Returns:

The name of the transform node.

hasInputs

public final boolean hasInputs()

For responses, this returns true if the service returned a value for the Inputs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

inputs

public final List<String> inputs()

The data inputs identified by their node names.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasInputs() method.

Returns:

The data inputs identified by their node names.

source

public final String source()

The source DynamicFrame that will be merged with a staging DynamicFrame.

Returns:

The source DynamicFrame that will be merged with a staging DynamicFrame.

hasPrimaryKeys

public final boolean hasPrimaryKeys()

For responses, this returns true if the service returned a value for the PrimaryKeys property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

primaryKeys

public final List<List<String>> primaryKeys()

The list of primary key fields to match records from the source and staging dynamic frames.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPrimaryKeys() method.

Returns:

The list of primary key fields to match records from the source and staging dynamic frames.

toBuilder

public Merge.Builder toBuilder()

Specified by:

toBuilder in interface ToCopyableBuilder<Merge.Builder,Merge>

builder

toString

public final String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

                                              Class<T> clazz)
