Hi, Fathima,

Yes, the most efficient way to verify if a message is sent successfully is
through the producer callback. You can take a look at PrintInfoCallback in
org.apache.kafka.toolsVerifiableProducer as an example. Our system tests
use that to verify if any data loss has occurred.

Thanks,

Jun
