Boto3 S3 StreamingBody().read() reads once and returns nothing after that

>>> a = client.get_object(Bucket='imgtest',Key='testimage1.jpg')
>>> a['Body'].read()
b'...\xadk\xc9,\xda\xe7\xcb\xb7$\x91\xf7\xb3\xd3>\xd5V...'
>>> a['Body'].read()
b''

complete bytes removed for brevity. I get an object, and read it. Then I read it again, but no bytes are returned.

If this stream acts as a normal file IO stream, how can I seek to the beginning of the stream? seek() does not seem to be a method on the streamingBody object.

Is there a reason why the StreamingBody, is not seekable? This becomes quite problematic when attempting to download portions of large files asynchronously. And what is the recommended way to do this?

If someone is having the problem 'bytes' object has no attribute 'seek' I solved with the following:

  obj = s3.get_object(Bucket='Mybucket', Key='MyObjKey')
  body = obj['Body']
  file_like_obj = io.BytesIO(body.read())
