> Aliyun OSS will support shallow copy which means server will only copy
> metadata when copy object operation occurs.
> With shallow copy, we can use copyObject api instead of multi-part copy api
> if we do not change object storage type & encryption type & source object is
> uploaded by Put / Multipart upload api.
> We will try to use copyObject api, and check result. If shallow copy disabled
> for this object, then we will use multipart copy. So, I will remove
> fs.oss.multipart.upload.threshold configuration.
