Produce example

Producing single message

/**
 * @var YiiKafkaComponent $kafka
 */
$kafka = \Yii::$app->kafka;

$producer = $kafka->getProducer();
$topicName = "test-topic"
$producer->send($topicName, 'Message: ' . date('d.m H:i:s'), '');

Producing messages in batches

/**
 * @var YiiKafkaComponent $kafka
 */
$kafka = \Yii::$app->kafka;

$producer = $kafka->getProducer();
$topicName = "test-topic"
$messages = [
    new Message($topicName, 'Message 1: ' . date('d.m H:i:s')),
    new Message($topicName, 'Message 2: ' . date('d.m H:i:s')),
];

$producer->sendBatch($messages);

Consume example

Consuming messages from a topic from settings

/**
 * @var YiiKafkaComponent $kafka
 */
$kafka = \Yii::$app->kafka;

$consumer = $kafka->getConsumer();
$consumer->consume(function ($message) {
    var_dump($message);
});

Consuming messages from a topic from settings

/**
 * @var YiiKafkaComponent $kafka
 */
$kafka = \Yii::$app->kafka;
$topicName = 'another-topic';

$config = new ConsumerConfig($topicName);
$config->setClientId('client_2');
$config->setGroupIp('group_2');

$consumer = $kafka->getAdapterClient()->createConsumer($config);
$consumer->consume(function ($message) {
    var_dump($message);
});
