Kafka Data Sync: Methods Explained

There are two methods for synchronizing data in Kafka.

1. Using the synchronous sending method of the producer: Kafka producer offers a send() method that can send messages synchronously to the Kafka cluster. When the send() method is called, it will block until the message is successfully sent or fails to send. This approach ensures that messages are sent synchronously to the Kafka cluster and the results of the send can be confirmed.
2. By utilizing the transactional sending method of producers, Kafka also offers an approach that ensures the atomicity and consistency of messages. Starting a transaction, sending multiple messages to the Kafka cluster, and then committing the transaction guarantees that all messages are either successfully sent or all fail. The transactional sending method provides stronger data consistency and reliability, suitable for scenarios where data integrity is a high priority.
