 or the BigQuery column must be of string type, and the values must be set
 as valid strings conform to [RFC-1034](https://tools.ietf.org/html/rfc1034)
 with 1-63 characters. Otherwise, documents without valid IDs fail to be
 imported.

 Only set this field when using
 [GcsSource][google.cloud.discoveryengine.v1.GcsSource] or
 [BigQuerySource][google.cloud.discoveryengine.v1.BigQuerySource], and when
 [GcsSource.data_schema][google.cloud.discoveryengine.v1.GcsSource.data_schema]
 or
 [BigQuerySource.data_schema][google.cloud.discoveryengine.v1.BigQuerySource.data_schema]
 is `custom`. And only set this field when
 [auto_generate_ids][google.cloud.discoveryengine.v1.ImportDocumentsRequest.auto_generate_ids]
 is unset or set as `false`. Otherwise, an INVALID_ARGUMENT error is thrown.

 If it is unset, a default value `_id` is used when importing from the
 allowed data sources.
        string id_field = 9;
        Returns:
        This builder for chaining.

      • setIdFieldBytes

        public ImportDocumentsRequest.Builder setIdFieldBytes​(com.google.protobuf.ByteString value)
         The field in the Cloud Storage and BigQuery sources that indicates the
 unique IDs of the documents.

 For [GcsSource][google.cloud.discoveryengine.v1.GcsSource] it is the key of
 the JSON field. For instance, `my_id` for JSON `{"my_id": "some_uuid"}`.
 For [BigQuerySource][google.cloud.discoveryengine.v1.BigQuerySource] it is
 the column name of the BigQuery table where the unique ids are stored.

 The values of the JSON field or the BigQuery column are used as the
 [Document.id][google.cloud.discoveryengine.v1.Document.id]s. The JSON field
 or the BigQuery column must be of string type, and the values must be set
 as valid strings conform to [RFC-1034](https://tools.ietf.org/html/rfc1034)
 with 1-63 characters. Otherwise, documents without valid IDs fail to be
 imported.

 Only set this field when using
 [GcsSource][google.cloud.discoveryengine.v1.GcsSource] or
 [BigQuerySource][google.cloud.discoveryengine.v1.BigQuerySource], and when
 [GcsSource.data_schema][google.cloud.discoveryengine.v1.GcsSource.data_schema]
 or
 [BigQuerySource.data_schema][google.cloud.discoveryengine.v1.BigQuerySource.data_schema]
 is `custom`. And only set this field when
 [auto_generate_ids][google.cloud.discoveryengine.v1.ImportDocumentsRequest.auto_generate_ids]
 is unset or set as `false`. Otherwise, an INVALID_ARGUMENT error is thrown.

 If it is unset, a default value `_id` is used when importing from the
 allowed data sources.
        string id_field = 9;
        Parameters:
        value - The bytes for idField to set.
        Returns:
        This builder for chaining.
