Cluster: This is a set of Kafka brokers.

Zookeeper: This is a cluster coordinator—a tool with different services that are part of the Apache ecosystem.

Broker: This is a Kafka server, also the Kafka server process itself.

Topic: This is a queue (that has log partitions); a broker can run several topics.

Offset: This is an identifier for each message.

Partition: This is an immutable and ordered sequence of records continually appended to a structured commit log.

Producer: This is the program that publishes data to topics.

Consumer: This is the program that processes data from the topics.

Retention period: This is the time to keep messages available for consumption.

public interface Producer {

  void process(String message);                                   //1

  static void write(KafkaProducer<String, String> producer,
                    String topic, String message) {               //2
    ProducerRecord<String, String> pr = new ProducerRecord<>(topic, message);
    producer.send(pr);
  }

  static Properties createConfig(String servers) {                //3
    Properties config = new Properties();
    config.put("bootstrap.servers", servers);
    config.put("acks", "all");
    config.put("retries", 0);
    config.put("batch.size", 1000);
    config.put("linger.ms", 1);
    config.put("key.serializer",
        "org.apache.kafka.common.serialization.StringSerializer");
    config.put("value.serializer",
        "org.apache.kafka.common.serialization.StringSerializer");
    return config;
  }
}
