 If ``True`` (the default) documents will be inserted on the server serially, in the order provided. If an error occurs all remaining inserts are aborted. If ``False``, documents will be inserted on the server in arbitrary order, possibly in parallel, and all document inserts will be attempted. - `bypass_document_validation`: (optional) If ``True``, allows the write to opt-out of document level validation. Default is ``False``. :Returns: An instance of :class:`~pymongo.results.InsertManyResult`. .. seealso:: :ref:`writes-and-ids` .. note:: `bypass_document_validation` requires server version **>= 3.2** .. versionchanged:: 3.2 Added bypass_document_validation support .. versionadded:: 3.0 """
