target
The target document attribute or metadata field you want to alter when ingesting documents into Amazon Q.
For example, you can delete all customer identification numbers associated with the documents, stored in the document metadata field called 'Customer_ID' by setting the target key as 'Customer_ID' and the deletion flag to TRUE. This removes all customer ID values in the field 'Customer_ID'. This would scrub personally identifiable information from each document's metadata.
Amazon Q can't create a target field if it has not already been created as an index field. After you create your index field, you can create a document metadata field using DocumentAttributeTarget. Amazon Q will then map your newly created document attribute to your index field.
