Questions about fatal errors on consumer

[DianaPinheiro]

When consuming messages, if the event is of the kafka.error type, is it recommended to validate if the error is fatal and terminate the application?

My question is if the errors are all recoverable or if there is the slightest possibility of there being a non-recoverable error in the consumer.

Example:

for run {
	...
	switch e := ev.(type) {
	case *kafka.Message:
		fmt.Printf("%% Message on %s:\n%s\n",
			e.TopicPartition, string(e.Value))
		if e.Headers != nil {
			fmt.Printf("%% Headers: %v\n", e.Headers)
		}
		_, err := c.StoreMessage(e)
		if err != nil {
			fmt.Fprintf(os.Stderr, "%% Error storing offset after message %s:\n",
				e.TopicPartition)
		}
	case kafka.Error:
		
		// Is this validation recommended/necessary in the consumer?
		if e.IsFatal() {
			run = false
		}

	default:
		fmt.Printf("Ignored %v\n", e)
	}
		
}

Thank you so much
