> If the group-offset startup mode is directly used when the submitted offset does not exist in the Kafka consumer group, the Kafka source table will throw a NoOffsetForPartitionException;
> Therefore, if you want to use the group-offset startup mode, you must first start in another mode and submit the offset, and then use this mode;
> I think this behavior is unnecessary, so I think that when using the group-offset startup mode, it is allowed to set the "{*}auto.offset.reset{*}" parameter instead of forcing the use of "{*}OffsetResetStrategy.NONE{*}"
