-------------------------------

             Summary: Introduce Add broadcast output to broadcast events to all the downstream tasks
                 Key: FLINK-24644
                 URL: https://issues.apache.org/jira/browse/FLINK-24644
             Project: Flink
          Issue Type: Sub-task
          Components: Library / Machine Learning
            Reporter: Yun Gao
            Assignee: Yun Gao
             Fix For: 0.1.0


Iteration requires to broadcast the epoch-watermark inside iteration no matter what partitioner is used. Currently it is not directly supported by the DataStream API, thus we need use reflection to use some low-level operations to implement this functionality.
