Question: 1 / 400

Why is it recommended to retry sending messages?

Messages can be resent multiple times

To handle transient errors effectively

To increase the total message throughput

Both A and B are correct

Retrying message sending is a recommended practice primarily because it allows for effective handling of transient errors. Transient errors might occur due to temporary issues, such as network glitches or momentary unavailability of a broker, which can resolve themselves quickly. By implementing a retry mechanism, messages can be resent without losing valuable data, ensuring that the system remains resilient and capable of recovering from brief disruptions.

Additionally, the option regarding the ability to resend messages emphasizes Kafka's design to handle duplicates safely, as messages are identified by unique offsets in partitions. Thus, if a message does need to be resent, Kafka manages these duplicates appropriately, ensuring data integrity.

Overall, the practice of retrying message transmission not only safeguards against data loss due to transient issues but also capitalizes on Kafka's capabilities, making both aspects vital to maintaining a robust messaging system.
