> The property blockingConnectionsBetweenChains means, if there are some stream
> edges that can not be chained and the shuffle mode of edge is not specified,
> translate these edges into {{BLOCKING}} result partition type.
> The reason of introducing it is to satisfy the requirement of Blink batch
> planner. Because the current scheduling strategy is a bit simple. It can not
> support some complex scenarios, like a batch job with resources limited.
> To be honest, it's probably a work-around solution. However it's an internal
> implementation, we can replace it when we are able to support batch job by
> scheduling strategy.
