Can you elaborate a little why this is needed ? Usually the mapping should not be bottleneck and we try to avoid the explicit parallelism of the operator to reduce the data shuffle. The default parallelism would make the operator chain with the source.

[JerryYue-M]

@danny0405 ,the real problem is this operator just use the the default parallelism of job instead of source parallelism. in some case, we will set parallelism for each operator include source operator. so this function can't chain the source operator, just because it always use the job default parallelism when source don't use the default parallelism of job.
if source don't use the default parallelism of job, so do this.
