-----------------------------------
Summary: BasicOzoneFileSystem support batchRename folder.
Key: HDDS-3904
URL: https://issues.apache.org/jira/browse/HDDS-3904
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: Ozone Filesystem
Reporter: mingchao zhao
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.
