Hi, Stephan. Thank you for your response. But I would ask, if the issue
does not occur by the receiver of a channel starts much faster than the sender.
Like RuntimeException cause the task failed for several times. I do not know
how flink solve this, But I know spark the default if the task failed for 4
times. Then the job failed.---
