Steve Loughran commented on HADOOP-13600:
-----------------------------------------

If we do this using the same thread pool as for block uploads, then some 
priority queuing should be used for the renames, so that they get priority over 
uploads, the latter being much slower.

> S3a rename() to copy files in a directory in parallel

> 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
