title: multi-part upload Google Storage
body: <p>I'm trying to implement multi-part upload to Google Storage but to my surprise it does not seem to be straightforward (I could not find java example).</p>
  <p>Only mention I found was in the XML API <a href="https://cloud.google.com/storage/docs/multipart-uploads" rel="nofollow noreferrer">https://cloud.google.com/storage/docs/multipart-uploads</a></p>
  <p>Also found some discussion around a compose API <a href="https://github.com/googleapis/google-cloud-java/blob/c3d18ffce9d9895550dd5d2acc1d0ff125305898/google-cloud-examples/src/main/java/com/google/cloud/examples/storage/StorageExample.java#L446" rel="nofollow noreferrer">StorageExample.java#L446</a> mentioned here <a href="https://github.com/googleapis/google-cloud-java/issues/1440" rel="nofollow noreferrer">google-cloud-java issues 1440</a></p>
  <p>Any recommendations how to do multipart upload?</p>
