Andrew Gaul commented on JCLOUDS-894:
-------------------------------------
[~mgpotter] Fixes for this issue lay the groundwork for a portable
{{ParallelMultipartUploadStrategy}}. I still have some more fixes to the
slicer and additional provider support before I look at parallel uploads.
Would you like to look into this? It should be relatively straightforward to
implement and let's continue discussion in JCLOUDS-227.
> Expose component operations of multipart upload
> -----------------------------------------------
>
> Key: JCLOUDS-894
> URL: https://issues.apache.org/jira/browse/JCLOUDS-894
> Project: jclouds
> Issue Type: New Feature
> Components: jclouds-blobstore
> Affects Versions: 1.9.0
> Reporter: Andrew Gaul
> Assignee: Andrew Gaul
> Labels: multipart
>
> Presently jclouds exposes multipart upload via a simple interface:
> {code:java}
> blobStore.putBlob(containerName, blob, new PutOptions().multipart(true));
> {code}
> This does not allow more complicated interactions such as parallel uploads,
> uploads with unknown content-lengths, and other interfaces like writing into
> an {{OutputStream}}. Further the current {{MultipartUploadStrategy}}
> implementations duplicate code across the azureblob, gcs, and s3 providers.
> I propose to expose the MPU component operations, e.g., initiate, complete,
> abort, and upload part, via the {{BlobStore}} abstraction. This will allow
> us to address all the above features.
