Flink Jira Bot updated FLINK-3037: ---------------------------------- Labels: auto-deprioritized-major stale-minor (was: auto-deprioritized-major) I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help the community manage its development. I see this issues has been marked as Minor but is unassigned and neither itself nor its Sub-Tasks have been updated for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is still Minor, please either assign yourself or give an update. Afterwards, please remove the label or in 7 days the issue will be deprioritized. > Make the behavior of the Kafka consumer configurable if the offsets to > restore from are not available > ----------------------------------------------------------------------------------------------------- > > Key: FLINK-3037 > URL: https://issues.apache.org/jira/browse/FLINK-3037 > Project: Flink > Issue Type: Improvement > Components: Connectors / Kafka > Reporter: Robert Metzger > Priority: Minor > Labels: auto-deprioritized-major, stale-minor > > Currently, if the {{FlinkKafkaConsumer}} is restoring a checkpoint and the > offset is not available anymore in Kafka, its restoring according to > {{auto.offset.reset}}. > This leads to inconsistent behavior (not exactly-once anymore) because the > operators will not receive data in sync with the checkpoint. > With this pull request, I would like to make the behavior controllable, using > a flag. The simplest approach would be to let the consumer fail in that case. -- This message was sent by Atlassian Jira (v8.20.1#820001)
