Method Details

getTopology

public BrokerClusterState getTopology()

Description copied from interface: BrokerTopologyManager

Returns live topology that includes which brokers are available, who is leader for each partition, etc.

Specified by:

getTopology in interface BrokerTopologyManager

Returns:

a copy of the currently known topology

getClusterConfiguration

public ClusterConfiguration getClusterConfiguration()

Description copied from interface: BrokerTopologyManager

Returns the current cluster topology. The topology contains the information about brokers which are part of the cluster, and the partition distribution. Unlike BrokerClusterState this also includes information about brokers which are currently unreachable.

Specified by:

getClusterConfiguration in interface BrokerTopologyManager

addTopologyListener

public void addTopologyListener(BrokerTopologyListener listener)

Description copied from interface: BrokerTopologyManager

Adds the topology listener. For each existing brokers, the listener will be notified via BrokerTopologyListener.brokerAdded(MemberId). After that, the listener gets notified of every new broker added or removed events.

Specified by:

addTopologyListener in interface BrokerTopologyManager

Parameters:

listener - the topology listener

removeTopologyListener

public void removeTopologyListener(BrokerTopologyListener listener)

Description copied from interface: BrokerTopologyManager

Removes the given topology listener by identity.

Specified by:

removeTopologyListener in interface BrokerTopologyManager

Parameters:

listener - the listener to remove

getName

public String getName()

Overrides:

getName in class Actor

onActorStarted

protected void onActorStarted()

Overrides:

onActorStarted in class Actor

event

public void event(ClusterMembershipEvent event)

Specified by:

event in interface EventListener<ClusterMembershipEvent>

onClusterConfigurationUpdated

public void onClusterConfigurationUpdated(ClusterConfiguration clusterTopology)

Specified by:

onClusterConfigurationUpdated in interface ClusterConfigurationUpdateNotifier.ClusterConfigurationUpdateListener
