> An AWS SDK [issue|https://github.com/aws/aws-sdk-java/issues/367] highlights that metadata
isn't copied on large copies.
> 1. Add a test to do that large copy/rname and verify that the copy really works
> 2. Verify that metadata makes it over.
> Verifying large file rename is important on its own, as it is needed for very large commit
operations for committers using rename
