Ah, yes. > Hopefully my advice was OK regardless :) I agree with you. Although I go for a single top-level actor per JVM for the following two reasons: (1) Akka Typed (aka Akka 3?) has no actorOf, but instead you create an ActorSystem by passing Props for the single top-level actor (2) Typically the actors created by the single top-level actor are super important for the system to work properly and therefore the top-level actor needs a custom supervisor strategy – something you can only achieve with a configured SupervisorStrategyFactory for the guardian otherwise Heiko > > On Sat, Nov 28, 2015 at 1:03 PM, Heiko Seeberger <loe...@posteo.de > <mailto:loe...@posteo.de>> wrote: >> On 28 Nov 2015, at 18:47, Richard Rodseth <rrods...@gmail.com >> <mailto:rrods...@gmail.com>> wrote: >> >> One thing you can look into is using the EventBus to send "domain events" >> between top-level actors.
