What are the ways to transfer and exchange data using Kafka?

Apache Kafka provides several methods for data transmission and exchange:

• Producers send messages to Kafka topics.
• Consumers read messages from topics.
• Topics are logical channels for organizing data streams.

Methods of exchange:

• Publish/Subscribe (Pub/Sub): multiple consumers can subscribe to a single topic and receive messages.
• Message Queue: consumers can read messages from a topic in order, ensuring load balancing.

For integration with applications, Kafka clients are used in various languages (e.g., Java, Python). Example of sending a message in Java:

Producer<String, String> producer = new KafkaProducer<>(props);
producer.send(new ProducerRecord<>("topic", "key", "value"));
producer.close();

Thus, Kafka provides scalable and reliable message exchange between systems.
