        Description copied from interface: MessageProducer
        Asynchronously send a record to a specific topic and invoke the provided callback when the sending has been acknowledged. The sending is asynchronous and this method will return immediately once the record has been stored in the buffer of records waiting to be sent.
        Specified by:
        send in interface MessageProducer<K,​V>
        Parameters:
        key - key to send
        value - value to send
        headers - headers to include in the message
        callback - callback to invoke
        Returns:
        The result of sending is a RecordMetadata specifying the partition the record was sent to, the offset it was assigned and the timestamp of the record. Noop implementations may return null instead of a Future.

      • close

        public void close()

      • flush

        public void flush()
        Description copied from interface: MessageProducer
        This method is a blank default implementation in order to avoid it being a breaking change. The implementing class must override this to add behaviour to it. The implementation should call the flush() method of the producer.
        Specified by:
        flush in interface MessageProducer<K,​V>
