Batch(client, raise_exception=True)

Proxy an underlying connection, batching up change operations.

Warning: 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.

Parameters
Name	Description
client	Client The client to use for making connections.
raise_exception	bool (Optional) Defaults to True. If True, instead of adding exceptions to the list of return responses, the final exception will be raised. Note that exceptions are unwrapped after all operations are complete in success or failure, and only the last exception is raised.

Methods

current

current()

Return the topmost batch, or None.

finish

finish(raise_exception=True)

Submit a single multipart/mixed request with deferred requests.

Parameter
Name	Description
raise_exception	bool (Optional) Defaults to True. If True, instead of adding exceptions to the list of return responses, the final exception will be raised. Note that exceptions are unwrapped after all operations are complete in success or failure, and only the last exception is raised.

Returns
Type	Description
list of tuples	one (headers, payload) tuple per deferred request.
