> The {{setParallelism()}} method exist in many components from different
> levels. Some of the methods require the input value to be greater than {{1}}
> (e.g., {{StreamTransformation.setParallelism()}}), while some of them also
> allow the value to be {{ExecutionConfig.PARALLELISM_DEFAULT}}, which is
> {{-1}} by default (e.g., {{DataSink.setParallelism()}}). We need to unify the
> value checks for these methods.
