> {quote}We have only read(), we don't have read(byte[] b, int off, int len), we might
see some slow operation during put with SignedInputStream.  
> {quote}
> 100% agree. I didn't check any performance numbers, yet, but we need to do it sooner
or later. I would implement this method in a separate jira as it adds more complexity and
as of now I would like to support the mkdir operations of the s3a unit tests (where the size
is 0).
