[jira] [Created] (LIBCLOUD-895) Google Cloud Storage supports chunked uploads

Sumukh Sridhara created LIBCLOUD-895:
----------------------------------------

             Summary: Google Cloud Storage supports chunked uploads
                 Key: LIBCLOUD-895
                 URL: https://issues.apache.org/jira/browse/LIBCLOUD-895
             Project: Libcloud
          Issue Type: Bug
          Components: Storage
            Reporter: Sumukh Sridhara
            Priority: Minor


Google Cloud Storage supports chunked encoding for uploads. (Link: https://cloud.google.com/storage/docs/streaming) 

We enabled this and saw a 2-4x performance improvement on upload times (mainly because we didn't have to buffer the whole file) 

GoogleStorageDriver.supports_chunked_encoding is set to False currently but 

Changes required: 
- Change `supports_chunked_encoding` to True 
- Minor refactor to verify the hash when uploading via stream since we can calculate the hash. Google recommends verifying the hash for a streaming/chunked upload. The current implementation sets verify_hash=False and does not accept it as an argument. There are a variety of ways to fix this - but I'm not sure what would be best.
