Interface PartitionListener

All Known Implementing Classes:
BrokerHealthCheckService, CommandApiServiceImpl, TopologyManagerImpl
public interface PartitionListener
Can be implemented and used to react on partition role changes, like on Leader on Actor should be started and on Follower one should be removed. If this listener performs actions that are critical to the progress of a partition, it is expected to complete the future exceptionally on a failure. Otherwise the future should complete normally.
