A batch request is a single standard HTTP request containing multiple Cloud Storage JSON API calls. Within this main HTTP request, there are multiple parts which each contain a nested HTTP request. The body of each part is itself a complete HTTP request, with its own verb, URL, headers, and body. Note that Cloud Storage does not support batch operations for uploading or downloading. Additionally, the current batch design does not support library methods whose return values depend on the response payload. See more details in the [Sending Batch Requests official guide](https://cloud.google.com/storage/docs/batch). Examples of situations when you might want to use the Batch module: ``blob.patch()`` ``blob.update()`` ``blob.delete()`` ``bucket.delete_blob()`` ``bucket.patch()`` ``bucket.update()`` ) encode_noop) Generator)MIMEApplication) MIMEMultipart)ParserN)_helpers) exceptions) Connection)_DEFAULT_TIMEOUTcs eZdZdZfddZZS)MIMEApplicationHTTPa?MIME type for ``application/http``.
