-- | The target document attribute or metadata field you want to alter when
-- ingesting documents into Amazon Kendra.
--
-- For example, you can delete customer identification numbers associated
-- with the documents, stored in the document metadata field called
-- \'Customer_ID\'. You set 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 Kendra cannot 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
-- Kendra then will map your newly created metadata field to your index
-- field.
--
-- You can also use this with
-- <https://docs.aws.amazon.com/kendra/latest/dg/API_DocumentAttributeCondition.html DocumentAttributeCondition>.
