[jira] [Created] (FLINK-24646) Add operator wrapper for all-round iterations

Yun Gao created FLINK-24646:
-------------------------------

             Summary: Add operator wrapper for all-round iterations
                 Key: FLINK-24646
                 URL: https://issues.apache.org/jira/browse/FLINK-24646
             Project: Flink
          Issue Type: Sub-task
          Components: Library / Machine Learning
            Reporter: Yun Gao
            Assignee: Yun Gao
             Fix For: 0.1.0


Inside the iteration, we will also broadcast the special events to mark the end of rounds. To process these events, all the operators inside the iteration is wrapped with a specialized wrapper operator. 

There are two kinds of wrappers: the first wrapper would not recreate the users' operator for each round, and the second one would. This issue would implement the first kind.
