----------------------------------------
Summary: Experiment with ShareConsumer option to throw on poll if
there are unacked records
Key: KAFKA-18902
URL: https://issues.apache.org/jira/browse/KAFKA-18902
Project: Kafka
Issue Type: Sub-task
Reporter: Andrew Schofield
Assignee: Andrew Schofield
Fix For: 4.1.0
Currently, an application using explicit acknowledgement which neglects to
acknowledge all of the records received from calling `poll(Duration)` is
re-presented with the records on the next call to poll. This has been shown to
be confusing.
An option will be added, initially experimentally, to throw an exception on
poll instead. If the experiment is successful, this will become the new
behaviour.
