> 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
