             Summary: Avoid enforced processing during bootstrap phase
                 Key: KAFKA-7458
                 URL: https://issues.apache.org/jira/browse/KAFKA-7458
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang
            Assignee: Guozhang Wang


In KAFKA-3514, we introduced a new config for allowing users to delay enforcing processing without all input topic partitions to have data. This config's default value is 0, which means that as long as the first fetch does not contains some records for all the partitions it will fall into enforced processing immediately, which is a high risk especially under bootstrap case.

We should consider leveraging on pause / resume to make sure that upon starting, some partition indeed does not have any data before we fall into enforced processing
