----------------------------------
Summary: Console Consumer should only poll for up to max messages
Key: KAFKA-5327
URL: https://issues.apache.org/jira/browse/KAFKA-5327
Project: Kafka
Issue Type: Improvement
Components: tools
Reporter: Dustin Cote
Priority: Minor
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.
