forceScaleDown

public ActorFuture<ClusterConfigurationChangeResponse> forceScaleDown(ClusterConfigurationManagementRequest.BrokerScaleRequest forceScaleDownRequest)

Description copied from interface: ClusterConfigurationManagementApi

Forces a scale down of the cluster. The members that are not specified in the request will be removed forcefully. The replicas of partitions on the removed members won't be re-assigned. As a result the number of replicas for those partitions will be reduced.

This is expected to be used to force remove a set of brokers when they are unreachable.
