[jira] [Created] (FLINK-8229) Cannot use broadcast in StreamingEnvironment

Wind created FLINK-8229:
---------------------------

             Summary: Cannot use broadcast in StreamingEnvironment
                 Key: FLINK-8229
                 URL: https://issues.apache.org/jira/browse/FLINK-8229
             Project: Flink
          Issue Type: Improvement
            Reporter: Wind


Why not support broadcast variable in Datastream programs ? 
I am not sure if I am right, I guess it has the same mechanism as the dataset broadcast variable.
***
	@Override
	public <RT> List<RT> getBroadcastVariable(String name) {
		throw new UnsupportedOperationException("Broadcast variables can only be used in DataSet programs");
	}
***
