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, 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 translated 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 cost model.)
