Hello, While implementing the SAMOA adapter for Flink-Streaming we stumbled upon the need to allow loops (or circular dependencies) in the job graph. Many incremental machine learning tasks define loops already and there is no trivial way of getting around it. In the streaming job graph builder there is only a check that does not allow the user to submit graphs with loops, however, from what Gyula told me, if the check is removed the streaming job runs as expected. Is there (still) a major reason for having this check, at least in the streaming component?
