type Kafka 

type Kafka struct {
	// contains filtered or unexported fields
}

func (Kafka) Brokers 

func (kfk Kafka) Brokers() []*Broker

Brokers returns the current set of active brokers as retrieved from cluster metadata.

func (Kafka) Close 

func (kfk Kafka) Close() error

Close shuts down all broker connections managed by this client. It is required to call this function before a client object passes out of scope, as it will otherwise leak memory. You must close any Producers or Consumers using a client before you close the client.

func (Kafka) Closed 

func (kfk Kafka) Closed() bool

Closed returns true if the client has already had Close called on it

func (Kafka) Config 

func (kfk Kafka) Config() *ConfigKafka

Config returns the Config struct of the client. This struct should not be altered after it has been created.

func (Kafka) Controller 

func (kfk Kafka) Controller() (*Broker, error)

Controller returns the cluster controller broker. It will return a locally cached value if it's available. You can call RefreshController to update the cached value. Requires Kafka 0.10 or higher.

func (Kafka) Coordinator 

func (kfk Kafka) Coordinator(consumerGroup string) (*Broker, error)

Coordinator returns the coordinating broker for a consumer group. It will return a locally cached value if it's available. You can call RefreshCoordinator to update the cached value. This function only works on Kafka 0.8.2 and higher.

func (Kafka) GetOffset 

func (kfk Kafka) GetOffset(topic string, partitionID int32, time int64) (int64, error)

GetOffset queries the cluster to get the most recent available offset at the given time (in milliseconds) on the topic/partition combination. Time should be OffsetOldest for the earliest available offset, OffsetNewest for the offset of the message that will be produced next, or a time.

func (Kafka) InSyncReplicas 

func (kfk Kafka) InSyncReplicas(topic string, partitionID int32) ([]int32, error)

InSyncReplicas returns the set of all in-sync replica IDs for the given partition. In-sync replicas are replicas which are fully caught up with the partition leader.

func (Kafka) InitProducerID 

func (kfk Kafka) InitProducerID() (*InitProducerIDResponse, error)

InitProducerID retrieves information required for Idempotent Producer

func (Kafka) Leader 

func (kfk Kafka) Leader(topic string, partitionID int32) (*Broker, error)

Leader returns the broker object that is the leader of the current topic/partition, as determined by querying the cluster metadata.

func (Kafka) NewAsyncProducer 

func (kfk Kafka) NewAsyncProducer() (AsyncProducer, error)

func (Kafka) NewConsumer 

func (kfk Kafka) NewConsumer() (Consumer, error)

func (Kafka) NewConsumerGroup 

func (kfk Kafka) NewConsumerGroup(groupID string) (ConsumerGroup, error)

func (Kafka) NewSyncProducer 

func (kfk Kafka) NewSyncProducer() (SyncProducer, error)

func (Kafka) OfflineReplicas 

func (kfk Kafka) OfflineReplicas(topic string, partitionID int32) ([]int32, error)

OfflineReplicas returns the set of all offline replica IDs for the given partition. Offline replicas are replicas which are offline

func (Kafka) Partitions 

func (kfk Kafka) Partitions(topic string) ([]int32, error)

Partitions returns the sorted list of all partition IDs for the given topic.

func (Kafka) RefreshBrokers 

func (kfk Kafka) RefreshBrokers(addrs []string) error

RefreshBrokers takes a list of addresses to be used as seed brokers. Existing broker connections are closed and the updated list of seed brokers will be used for the next metadata fetch.

func (Kafka) RefreshController 

func (kfk Kafka) RefreshController() (*Broker, error)

RefreshController retrieves the cluster controller from fresh metadata and stores it in the local cache. Requires Kafka 0.10 or higher.

func (Kafka) RefreshCoordinator 

func (kfk Kafka) RefreshCoordinator(consumerGroup string) error

RefreshCoordinator retrieves the coordinator for a consumer group and stores it in local cache. This function only works on Kafka 0.8.2 and higher.

func (Kafka) RefreshMetadata 

func (kfk Kafka) RefreshMetadata(topics ...string) error

RefreshMetadata takes a list of topics and queries the cluster to refresh the available metadata for those topics. If no topics are provided, it will refresh metadata for all topics.

func (Kafka) Replicas 

func (kfk Kafka) Replicas(topic string, partitionID int32) ([]int32, error)

Replicas returns the set of all replica IDs for the given partition.

func (Kafka) Topics 

func (kfk Kafka) Topics() ([]string, error)

Topics returns the set of available topics as retrieved from cluster metadata.

func (Kafka) WritablePartitions 

func (kfk Kafka) WritablePartitions(topic string) ([]int32, error)

WritablePartitions returns the sorted list of all writable partition IDs for the given topic, where "writable" means "having a valid leader accepting writes".
