priyeshkaratha opened a new pull request, #11721:
URL: https://github.com/apache/ozone/pull/11721
## What changes were proposed in this pull request?
Before this change, changing any `ozone.om.key.lifecycle.service.*` property
meant restarting OM. This PR makes those properties reconfigurable at runtime
through the OM reconfiguration framework (`ozone admin reconfig --service=OM
... start`).
**Reconfigurable properties** (the new
`KeyLifecycleService.OZONE_KEY_LIFECYCLE_PROPERTIES` set):
- `ozone.om.key.lifecycle.service.enabled`
- `ozone.om.key.lifecycle.service.interval`
- `ozone.om.key.lifecycle.service.timeout`
- `ozone.om.key.lifecycle.service.workers`
- `ozone.om.key.lifecycle.service.delete.batch-size`
- `ozone.om.key.lifecycle.service.mpu.abort.limit.per.task`
- `ozone.om.key.lifecycle.service.delete.cached.directory.max.count`
- `ozone.om.key.lifecycle.service.state.save.interval.ms`
- `ozone.om.key.lifecycle.service.state.save.keys.processed`
- `ozone.om.key.lifecycle.service.move.to.trash.enabled`
