> Follow up of FLINK-15670
> *Separate sink (producer) and source (consumer) to different jobs*
> * In the same job, a sink and a source are recovered independently according
> to regional failover. However, they share the same checkpoint coordinator and
> correspondingly, share the same global checkpoint snapshot.
> * That says if the consumer fails, the producer can not commit written data
> because of two-phase commit set-up (the producer needs a checkpoint-complete
> signal to complete the second stage)
> * Same applies to the producer
