> Dear Developers,
> It was not easy, but using S3 API, it was possible to upload a large blob from stream - without knowing its size in advance (and storing all the data locally). I found solutions using jclouds' aws-s3 specific API (some async interface), but I really miss this feature from jclouds' general API.
> My dream is to have a method like:
> blob.getOutputStream() into which I can write as many data as I want, 
> which pushes data to the storage simultaneously until I close the stream.
> (When I used S3, I created a wrapper class extending OutputStream, which initiates multipart upload, buffers data written to the output stream, writes a part when the buffer is full, and finalizes multipart upload on stream close.) 
> I don't know it is possible for all providers, but I really miss it...
> Thank you,
> Akos Hajnal
