Hello Robert Thanks to your reply I discovered the Stateful Functions which I believe is a quite powerful tool. I have some questions:
1) As you said, "the community is currently in the process of releasing the first Apache release of StateFun and it should hopefully be out by the end of this week". Does this mean that it will become available in Maven Repository? Because I can't find it while searching in https://mvnrepository.com/artifact/org.apache.flink?sort=newest or use the API in my intellij project when I import the dependencies in my POM file. I though of dowloading the code from https://ci.apache.org/projects/flink/flink-statefun-docs-master/, compiling it with *mvn clean package* and then import the produced jar file to my intellij project as an External Library. Is this what you might recommend for now? 2) I came across this tutorial by Stefan on stateful functions https://www.youtube.com/watch?v=fCeHCMJXXM0 where he mentions that arbitrary communication between nodes/functions/actors is essentially made possible by introducing feedback loops to the DAG Flink topology (well now it has circles I guess :P) to simulate the arbitrary messasing defined in the StateFun topology. So the message passing is done by "feedback and tuple rerouting" and not with MPI. Do you think (or have tested) if one may *efficiently* send/receive (potentially large) state, like graph state which is the use case of this post? Or it is more suitable for sending control messages between actors/functions? Thanks a lot in advance. Best, Max -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
