---------------------------------
Resolution: Duplicate
> BasicOzoneFileSystem support batchRename folder.
> ------------------------------------------------
>
> Key: HDDS-3904
> URL: https://issues.apache.org/jira/browse/HDDS-3904
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: Ozone Filesystem
> Reporter: mingchao zhao
> Priority: Major
>
> Currently rename folder is to get all the keys, and then rename them one by
> one. This makes for poor performance.
> HDDS-2939 can able to optimize this part, but at present the HDDS-2939 is
> slow and still a long way to go. So we optimized the batch operation based on
> the current interface. We were able to get better performance with this PR
> before the HDDS-2939 came in.
