Kafka Consumer Group Name not set if no checkpointing?

[John Smith]

Hi using flink 1.14.3, I have a job that doesn't use checkpointing. I have
noticed that the Kafka Consumer Group is not set?

I use Kafka Explorer to see all the consumers and when I run the job I
don't see the consumer group. Finally I decided to enable checkpointing and
restart the job and finally saw the consumer group.

Is this expected behaviour?
