>            Priority: Major
> # Setting high priority on intermediate streams caused starvation on certain 
> tasks. Due to the intermediate message kept coming, the input streams are not 
> consumed and watermark messages are not generated, which makes downstream 
> accumulates large state and makes processing slower thus make starvation 
> worse.
>  # Watermark broadcast needs to check whether the watermark is advanced.
