Documentation
runProducer :: ProducerProperties -> (KafkaProducer -> IO (Either KafkaError a)) -> IO (Either KafkaError a) Source #
Runs Kafka Producer.
The callback provided is expected to call produceMessage
or/and produceMessageBatch to send messages to Kafka.
newProducer :: MonadIO m => ProducerProperties -> m (Either KafkaError KafkaProducer) Source #
Creates a new kafka producer
A newly created producer must be closed with closeProducer function.
produceMessage :: MonadIO m => KafkaProducer -> ProducerRecord -> m (Maybe KafkaError) Source #
Sends a single message.
Since librdkafka is backed by a queue, this function can return before messages are sent. See
flushProducer to wait for queue to empty.
Arguments
| :: MonadIO m | |
| => KafkaProducer | |
| -> [ProducerRecord] | |
| -> m [(ProducerRecord, KafkaError)] | An empty list when the operation is successful, otherwise a list of "failed" messages with corresponsing errors. |
Sends a batch of messages.
Returns a list of messages which it was unable to send with corresponding errors.
Since librdkafka is backed by a queue, this function can return before messages are sent. See
flushProducer to wait for queue to empty.
flushProducer :: MonadIO m => KafkaProducer -> m () Source #
Drains the outbound queue for a producer.
This function is also called automatically when the producer is closed
with closeProducer to ensure that all queued messages make it to Kafka.
closeProducer :: MonadIO m => KafkaProducer -> m () Source #
Closes the producer. Will wait until the outbound queue is drained before returning the control.
data RdKafkaRespErrT Source #
