Description

Currently, FlinkTopologyBuilder cannot handle cyclic topologies. In order to implement this feature correctly, FlinkTopologyBuilder must first detect cycles in the topology and assembly the Flink streaming program accordingly.

As Storm allows for arbitrary dataflow structure, multiple cycles would be allows. Not sure if Flink can handle those.
