That answer is nearly 2 years old.

You can use a ListenerContainerCustomizer bean to configure a DefaultErrorHandler with a DeadLetterPublishingRecoverer which is configured with a KafkaTemplate to send the record to a different cluster.

Disable retries/DLT in the binder and configure the error handler with the desired retry characteristics.
