Examples with KafkaProducerRecord io.vertx.kafka.client.producer.KafkaProducerRecord used on opensource projects

Example 1 with KafkaProducerRecord

use of io.vertx.kafka.client.producer.KafkaProducerRecord in project hono by eclipse.

the class AbstractKafkaBasedMessageSender method sendAndWaitForOutcome.

/**
 * Sends a message to a Kafka broker and waits for the outcome.
 *
 * @param topic The topic to send the message to.
 * @param tenantId The tenant that the device belongs to.
 * @param deviceId The device identifier.
 * @param payload The data to send or {@code null} if the message has no payload.
 * @param headers Additional meta data that should be included in the message.
 * @param currentSpan The <em>OpenTracing</em> span used to use for tracking the sending of the message.
 *             The span will <em>not</em> be finished by this method.
 * @return A future indicating the outcome of the operation.
 *         <p>
 *         The future will be succeeded if the message has been sent.
 *         <p>
 *         The future will be failed with a {@link org.eclipse.hono.client.ServerErrorException} if the data could
 *         not be sent. The error code contained in the exception indicates the cause of the failure.
 * @throws NullPointerException if topic, tenantId, deviceId, headers or span are {@code null}.
