KRaft Management

If you are running your cluster in KRaft mode you can use Kpow to view the replicas that are either voters or observers in the Raft quorum.

Kpow's KRaft UI is accessible via the Brokers menu.

Unregister Brokers

The only action available in the KRaft UI is the ability to unregister brokers from a cluster. Unregistering a broker does not have any effect on partition assignments.

To unregister a broker navigate to the KRaft UI, select the replica you wish to unregister from the table and click the actions button. Within the menu click on the "Unregister Broker" action and a confirmation modal will appear.

Unregistering brokers requires the BROKER_UNREGISTER RBAC action.
