[Shang Yuanchun (Jira)]

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

             Summary: Remove implicit sinks
                 Key: FLINK-3959
                 URL: https://issues.apache.org/jira/browse/FLINK-3959
             Project: Flink
          Issue Type: Sub-task
          Components: Streaming
            Reporter: Stephan Ewen
             Fix For: 2.0.0


Right now, streaming programs need not specify a sink. All transformations that are not consumed are implicitly sinks.

That behavior makes it hard to lazily construct the stream graph on execution, and prevents interactive sessions on streams.
