------------------------------------
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
