> 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 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.
