godfrey he updated FLINK-5342:
------------------------------
Description: On Flink table API, a query will be translated to operators
without parallelism. And user do not know even do not care the target operators
translated from query. 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
translated to operators without parallelism. And user do not know even do not
care 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.)
