C# Class Kafka.Client.Producers.Partitioning.ZKBrokerPartitionInfo

Fetch broker info like ID, host, port and number of partitions from ZooKeeper.

Used when zookeeper based auto partition discovery is enabled

Inheritance: IBrokerPartitionInfo, IZooKeeperStateListener

Public Methods

Method	Description
Dispose ( ) : void	Closes underlying connection to ZooKeeper
GetAllBrokerInfo ( ) : Broker>.IDictionary	Gets a mapping from broker ID to the host and port for all brokers
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.
HandleStateChanged ( ZooKeeperStateChangedEventArgs args ) : void	Called when the ZooKeeper connection state has changed. Do nothing, since zkclient will do reconnect for us.
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.

Method	Description
BootstrapWithExistingBrokers ( string topic ) : SortedSet	Add the all available brokers with default one partition for new topic, so all of the brokers participate in hosting this topic Since we do not have the in formation about number of partitions on these brokers, just assume single partition just pick partition 0 from each broker as a candidate
EnsuresNotDisposed ( ) : void	Ensures that object was not disposed
InitializeBrokers ( ) : void	Initializes the list of brokers.
InitializeTopicBrokerPartitions ( ) : void	Initializes the topic - broker's partitions mappings.
RegisterListeners ( ) : void	Registers the listeners under several path in ZooKeeper to keep related data structures updated. Watch on following path: /broker/topics /broker/topics/[topic] /broker/ids
Reset ( ) : void	Resets the related data structures

Closes underlying connection to ZooKeeper
