> In {{S3ADataBlocks::ByteArrayBlock}}, data is copied whenever {{startUpload}}
> is called. It might be possible to directly access the byte[] array from
> ByteArrayOutputStream.
> Might have to extend ByteArrayOutputStream and create a method like
> getInputStream() which can return ByteArrayInputStream. This would avoid
> expensive array copy during large upload.
