-------------------------------------
Summary: Guarantees for producer callbacks on transaction commit
should be documented
Key: KAFKA-13967
URL: https://issues.apache.org/jira/browse/KAFKA-13967
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: Chris Egerton
Assignee: Chris Egerton
As discussed in
https://github.com/apache/kafka/pull/11780#discussion_r891835221, part of the
contract for a transactional producer is that all callbacks given to the
producer will have been invoked and completed (either successfully or by
throwing an exception) by the time that {{KafkaProducer::commitTransaction}}
returns. This should be documented so that users of the clients library can
have a guarantee that they're not on the hook to do that kind of bookkeeping
themselves.
