             Summary: Add periodic offset commit to Kafka Consumer if checkpointing is disabled
                 Key: FLINK-2974
                 URL: https://issues.apache.org/jira/browse/FLINK-2974
             Project: Flink
          Issue Type: Improvement
          Components: Kafka Connector
            Reporter: Robert Metzger


Flink only writes the offsets from the consumer into ZK if checkpointing is enabled.

We should have a similar feature to Kafka's autocommit in our consumer.
