Kafka manual ackMode MANUAL_IMMEDIATE what if not acknowledge

问题

I use Spring KafKa anf I set ackMode to MANUAL_IMMEDIATE

props.setAckMode(AbstractMessageListenerContainer.AckMode.MANUAL_IMMEDIATE);

the scenario is that for some reason my app could not acknowledge (acknowledgment.acknowledge()) and just miss it without exception.

1- How can I set consumer retry for missed message 2- How configure to call a function after max retry count that I configured reached

See the documentation about SeekToCurrentErrorHandlers.

When the listener throws an exception, the error handler will perform the necessary seeks and re-fetch the record. You can set the number of attempts before giving up.

There is also a DeadLetterPublishingRecoverer which can be used to send the failed record to another topic.
