Subject [jira] [Created] (FLINK-2836) Cyclic Topologies not supported
Date Thu, 08 Oct 2015 13:57:27 GMT
Matthias J. Sax created FLINK-2836:

             Summary: Cyclic Topologies not supported
                 Key: FLINK-2836
                 URL: https://issues.apache.org/jira/browse/FLINK-2836
             Project: Flink
          Issue Type: Improvement
          Components: Storm Compatibility
            Reporter: Matthias J. Sax

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.
