To create a BigMessage, you should create a BigMessage object and pass in a file-like object as the ``body`` param and also pass in the an S3 URL specifying the bucket in which to store the message body:: import boto.sqs from boto.sqs.bigmessage import BigMessage sqs = boto.sqs.connect_to_region('us-west-2') queue = sqs.get_queue('myqueue') fp = open('/path/to/bigmessage/data') msg = BigMessage(queue, fp, 's3://mybucket') queue.write(msg) Passing in a fully-qualified S3 URL (e.g. s3://mybucket/foo) is interpreted to mean that the body of the message is already stored in S3 and the that S3 URL is then used directly with no content uploaded by BigMessage.
