KillSupervisorsCustomDuty (druid-server 29.0.1 API)

java.lang.Object
- org.apache.druid.server.coordinator.duty.MetadataCleanupDuty
- - org.apache.druid.server.coordinator.duty.KillSupervisorsCustomDuty

All Implemented Interfaces:

CoordinatorCustomDuty, CoordinatorDuty
```
public class KillSupervisorsCustomDuty
extends MetadataCleanupDuty
implements CoordinatorCustomDuty
```
Example CoordinatorCustomDuty for automatic deletion of terminated supervisors from the metadata storage. This duty has the same implementation as KillSupervisors but uses a different configuration style as detailed in CoordinatorCustomDuty.
This duty is only an example to demostrate the usage of coordinator custom duties. All production clusters should continue using KillSupervisors.
In the future, we might migrate all metadata management coordinator duties to CoordinatorCustomDuty but until then this class will remain undocumented.
