without parallelism. And user do not know the target operators translated from
query, and can not set parallelism. So it's better to set the parallelism
automatically for each operator base on cost model. (was: On Flink table API,
a query will be translate to operators without parallelism. And user do not
know the target operators translated from query, and can not set parallelism.
So it's better to set the parallelism automatically for each operator base on
