> The ConsoleConsumer has a --max-messages flag that can be used to limit the number of messages consumed. However, the number of records actually consumed is governed by max.poll.records. This means you see one message on the console, but your offset has moved forward a default of 500, which is kind of counterintuitive. It would be good to only commit offsets for messages we have printed to the console.
