Review comment:
I'm assuming that you are asking about the resumed
`KafkaSourceDescriptor`. It depends on the status when it gets re-starting. If
the `KafkaSourceDescriptor` is no longer available, the `ReadFromKafkaDoFn`
will return `stop()`. Otherwise the DoFn will output records from this
`KafkaSourceDescriptor` till next checkpoint happens.
