> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.7.3
> Reporter: Steve Loughran
> Assignee: Sahil Takiar
>
> Currently a directory rename does a one-by-one copy, making the request
> O(files * data). If the copy operations were launched in parallel, the
> duration of the copy may be reducable to the duration of the longest copy.
> For a directory with many files, this will be significant
