Review comment:
This design is because the parallelism of some operators can only be a
certain value. For example, `GlobalAgg`, it's parallelism can only be 1. In
this case, the parallelism of `GlobalAgg` will be set to 1 in jobgraph during
compilation, and the adaptive batch scheduler will not change it's parallelism.
