Qingsheng Ren created FLINK-24277: ------------------------------------- Summary: Offset commit should be disabled if consumer group ID is not specified in KafkaSource Key: FLINK-24277 URL: https://issues.apache.org/jira/browse/FLINK-24277 Project: Flink Issue Type: Bug Components: Connectors / Kafka Affects Versions: 1.14.0 Reporter: Qingsheng Ren Fix For: 1.14.0
FLINK-24051 made "group.id" an optional configuration in KafkaSource. However, KafkaSource will generate a random group id if user doesn't specify one, and this random ID is inconsistent after failover, and not even human readable. A solution will be adding a configuration for offset commit on checkpoint, make it as true by default, and disable offset commit if group id is not specified. -- This message was sent by Atlassian Jira (v8.3.4#803005)
