That sample looks suspiciously like calling actor internals from another thread (saveStateOnDb from inside the future) which you should never do. See explanation in the docs here: http://doc.akka.io/docs/akka/current/scala/general/jmm.html#futures-and-the-java-memory-model
One way to simplify is to use the pipe-pattern and get the future result as a message to your actor, if the future is failed the exception will be wrapped in a akka.actor.Status.Failure and that is sent to the actor and you can deal with it in any way you'd like in the actor receive logic. If the correct reaction to it is to throw or stop actor or send a message to some other actor depends on the specific problem you are solving. If the actor models a request response then the right thing would be to stop and or tell someone about the failure, if it models a remote API where multiple requests flows through it you wouldn't want to stop it. If the failure could have damaged the internal state you would want to restart etc. -- Johan Akka Team On Mon, Aug 21, 2017 at 3:02 PM, Isaias Barroso <[email protected]> wrote: > Hi, all. > > Suppose I have an actor and I need to interrupt an execution based on a > Future exception, for example, like at that pseudo code: > https://gist.github.com/isaias/0445b5c32fd1905aba8cd18294672e25 > > Should throw the exception and let supervisor decide what to do?
