> 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.
