             Summary: Setting the parallelism automatically for DataSet Operators base on cost model
                 Key: FLINK-5342
                 URL: https://issues.apache.org/jira/browse/FLINK-5342
             Project: Flink
          Issue Type: Improvement
          Components: Table API & SQL
            Reporter: godfrey he


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 cost model.
