-----------------------------------

             Summary: InputStreamPayloadIterator.getNextPayload buffers entire part in-memory
                 Key: JCLOUDS-814
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-814
             Project: jclouds
          Issue Type: Improvement
          Components: jclouds-blobstore
    Affects Versions: 1.8.1
            Reporter: Andrew Gaul


This can cause {{OutOfMemoryErrors}} when using large multi-part part sizes or multiple concurrent multi-part {{putBlobs}}.  Instead jclouds should return a partial {{InputStream}} via {{ByteStreams.limit}}.  This has some complications since jclouds needs to know the content-length of the part which may be less than the chunk size.  After this change, use of {{InputStream}} will preclude use of parallel multi-part gets.
