append Parameters

When you define an append transformation in the dataflow JSON, you set the action attribute to append and specify the parameters.

This table describes the settings for the append node in the dataflow editor.

Setting	Required?	Value
Sources	Yes	Nodes in the dataflow that identify the dataset that you want to merge.
Allow disjoint schema	No	Select to allow appending of datasets with different schema. If this setting isn’t selected, appending datasets with different schemas causes the dataflow to fail.

This table describes the input parameters for the append transformation in the dataflow JSON.

Parameter Required? Value

sources Yes Nodes in the dataflow definition file that identify the dataset that you want to merge.

enableDisjointedSchemaMerge

Parameter	Required?	Value
sources	Yes	Nodes in the dataflow definition file that identify the dataset that you want to merge.
enableDisjointedSchemaMerge	No	Indicates whether appending datasets with different schema is allowed. To allow appending of disjoint schema, set to true. To prevent appending of disjoint schema, set to false. The default is false. Example: `"enableDisjointedSchemaMerge": true` If this parameter is set to false, appending datasets with different schemas causes the dataflow to fail.

Indicates whether appending datasets with different schema is allowed.

Example:
