             Summary: S3a rename() to copy files in a directory in parallel
                 Key: HADOOP-13600
                 URL: https://issues.apache.org/jira/browse/HADOOP-13600
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 2.7.3
            Reporter: Steve Loughran


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
