> Large scale DistCP with the -delete option doesn't finish in a viable time because of
the final CopyCommitter doing a 1 by 1 delete of all missing files. This isn't randomized
(the list is sorted), and it's throttled by AWS.
> If bulk deletion of files was exposed as an API, distCP would do 1/1000 of the REST calls,
so not get throttled.
> Proposed: add an initially private/unstable interface for stores, {{BulkDelete}} which
declares a page size and offers a {{bulkDelete(List<Path>)}} operation for the bulk
deletion.
