Hi Igal, I read that, To solve the following use case, What will be the best option between Flink or Flink Stateful Functions or Akka FSM? http://thatgamesguy.co.uk/articles/modular-finite-state-machine-in-unity/ or these images: https://imgur.com/a/MV62BlO
Was looking for an in-depth comparison of Akka FSM vs Flink Stateful Functions..
