--------------------------------------
Summary: OzoneConfiguration.of() is expensive
Key: HDDS-10005
URL: https://issues.apache.org/jira/browse/HDDS-10005
Project: Apache Ozone
Issue Type: Improvement
Reporter: Wei-Chiu Chuang
Attachments: Screenshot 2023-12-22 at 11.31.33 AM.png
Several APIs in BasicRootedOzoneFileSystem invokes OzoneConfiguration.of().
This is expensive because each invocation creates a new copy of
OzoneConfiguration and it needs to be loaded from Configuration object.
Especially for rename() where it creates the same OzoneConfiguration object
twice.
Proposal: create one copy of OzoneConfiguration and use it throughout the life
cycle of the file system object.
