Functions

func WithDurationOffset

func WithDurationOffset(since time.Duration, timeExtractor TimeExtractor) kafka.OptionFunc

WithDurationOffset allows creating a consumer from a given duration. It accepts a function indicating how to extract the time from a Kafka message.

func WithNotificationOnceReachingLatestOffset

func WithNotificationOnceReachingLatestOffset(ch chan<- struct{}) kafka.OptionFunc

WithNotificationOnceReachingLatestOffset closes the input channel once all the partition consumers have reached the latest offset.

func WithTimestampOffset

func WithTimestampOffset(since time.Duration) kafka.OptionFunc

WithTimestampOffset allows creating a consumer from a given duration.

Types

type Factory

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

func New

func New(name, topic string, brokers []string, saramaCfg *sarama.Config, oo ...kafka.OptionFunc) (*Factory, error)

New constructor.

func (*Factory) Create

func (f *Factory) Create() (async.Consumer, error)

Create a new asynchronous consumer.

type TimeExtractor

type TimeExtractor func(*sarama.ConsumerMessage) (time.Time, error)

TimeExtractor defines a function extracting a time from a Kafka message.
