Types

type KafkaCluster

type KafkaCluster interface {
	NewConsumer(groupID string, topics []string) (KafkaConsumer, error)

	GetConsumerMode() cluster.ConsumerMode
}

type KafkaConsumer

type KafkaConsumer interface {
	Messages() <-chan *sarama.ConsumerMessage
	Partitions() <-chan cluster.PartitionConsumer
	MarkOffset(msg *sarama.ConsumerMessage, metadata string)
	Close() (err error)
}

type KafkaDispatcher

	// contains filtered or unexported fields
}

func NewDispatcher

func (*KafkaDispatcher) UpdateKafkaConsumers

func (d *KafkaDispatcher) UpdateKafkaConsumers(config *multichannelfanout.Config) (map[eventingduck.SubscriberSpec]error, error)

UpdateKafkaConsumers will be called by new CRD based kafka channel dispatcher controller, instead of UpdateConfig.

	ClientID     string
	Brokers      []string
	ConsumerMode cluster.ConsumerMode
	TopicFunc    TopicFunc
