sarvekshayr opened a new pull request, #9599:
URL: https://github.com/apache/ozone/pull/9599
## What changes were proposed in this pull request?
- `ContainerToKeyMapping` now handles both FSO and OBS keys as a container
may contain both types of keys.
- Introduced a flag `--onlyFileNames` that allows listing only file names
without rebuilding the full FSO tree in case of FSO keys. This significantly
reduces processing time when we only need to quickly check whether any keys are
affected.
