             Summary: Investigate resetting offsets in 
SubscriptionState.resetInitializingPositions()
                 Key: KAFKA-15652
                 URL: https://issues.apache.org/jira/browse/KAFKA-15652
             Project: Kafka
          Issue Type: Sub-task
          Components: clients, consumer
            Reporter: Kirk True
            Assignee: Kirk True


In the {{assign()}} method implementation, both {{KafkaConsumer}} and 
{{PrototypeAsyncConsumer}} commit offsets asynchronously. Is this intentional? 
[~junrao] asks in a [recent PR 
review|https://github.com/apache/kafka/pull/14406/files/193af8230d0c61853d764cbbe29bca2fc6361af9#r1349023459]:
{quote}Do we guarantee that the new owner of the unsubscribed partitions could 
pick up the latest committed offset?

Let's confirm whether the asynchronous approach is acceptable and correct. If 
it is, great, let's enhance the documentation to briefly explain why. If it is 
not, let's correct the behavior if it's within the API semantic expectations.
