```
In the create statement example below, you can see
The user didn't specify the custom partitions.
So that 1. Fe will get all kafka partitions from server in routine load's scheduler.
The user set the default offset by datetime.
So that 2. Fe will get kafka offset by time from server in routine load's scheduler.
When 1 is success, meanwhile 2 is failed, the progress of this routine load may not contains any partitions and offsets.
Nevertheless, since newCurrentKafkaPartition which is get by kafka server may be always equal to currentKafkaPartitions,
the wrong progress will never be updated.
