GetBrokerInfo ( int brokerId ) : Broker	Gets the host and port information for the broker identified by the given broker ID
GetBrokerPartitionInfo ( string topic ) : SortedSet	Gets a mapping from broker ID to partition IDs
HandleSessionCreated ( ZooKeeperSessionCreatedEventArgs args ) : void	Called after the ZooKeeper session has expired and a new session has been created. We would have to re-create any ephemeral nodes here.

ZKBrokerPartitionInfo ( IZooKeeperClient zkclient ) : System	Initializes a new instance of the ZKBrokerPartitionInfo class.
ZKBrokerPartitionInfo ( Kafka.Client.Cfg.ProducerConfiguration config, Action callback ) : System	Initializes a new instance of the ZKBrokerPartitionInfo class.
