Tzu-Li (Gordon) Tai commented on FLINK-31305: --------------------------------------------- thanks [~mason6345] for the ping! I've actually been discussing your changes with Raman Verma, who has did a review already on the PR. I'll also do a pass tomorrow and then will try to merge this by end of this week. > KafkaWriter doesn't wait for errors for in-flight records before completing > flush > --------------------------------------------------------------------------------- > > Key: FLINK-31305 > URL: https://issues.apache.org/jira/browse/FLINK-31305 > Project: Flink > Issue Type: Bug > Components: Connectors / Kafka > Affects Versions: 1.17.0, 1.16.1 > Reporter: Mason Chen > Assignee: Mason Chen > Priority: Major > Labels: pull-request-available > Fix For: 1.17.0 > > > The KafkaWriter flushing needs to wait for all in-flight records to send > successfully. This can be achieved by tracking requests and returning a > response from the registered callback from the producer#send() logic. > There is potential for data loss since the checkpoint does not accurately > reflect that all records have been sent successfully, to preserve at least > once semantics. -- This message was sent by Atlassian Jira (v8.20.10#820010)
