GrantPSpencer opened a new pull request, #2724:
URL: https://github.com/apache/helix/pull/2724
### Issues
- [x] CustomizedStateProvider APIs only allow operations at a per partition
level on a single instance. If a user wants to completely wipe a
customizedState for a given resource or for all resources using this API, they
currently need to implement logic to identify all relevant partitions and then
delete them one by one.
### Description
- [x] CustomizedStateProvider provides APIs to get, set, and delete
customizedState information on a specific instance. This PR adds the ability to
delete customizedState information at either the customizedStateName or
resource level, which will allow for faster cleanup.
### Tests
- [x] testDeleteResourceCustomizedState - tests successful delete, deletes
on non-existent resource and customizedState
- [x] testDeleteAllResourcesCustomizedState - tests successful delete,
deletes when no resources present and on non-existent customizedState
### Changes that Break Backward Compatibility (Optional)
None. No changes to current APIs, only new features added.
