Hi, I'd like clarification regarding something Roland mentioned in the Coursera Reactive Programming class (which my co-workers and I have really found useful - nice job Roland!). In one of the lectures he was discussing the guarantee that Akka makes regarding the order in which messages are received -- specifically that messages between sender-receiver actor pairs will not be delivered out of order.
We'd like to know how the guarantee applies when the sender is not explicitly an Actor but some other object that has obtained an ActorRef via actorSelection? If I look up the ref once and cache it and then send multiple messages using that same ref instance, does the same guarantee apply as between actor pairs? What if I don't cache the ref but select it each time this object wants to send a message to that same actor ref? Guessing that even though my object that is sending messages is not an actor, under the covers and in order for the message send to work correctly, an implicit sender Actor is created and then the message order guarantee applies between that sender-receiver pair? So, as long as I cache the ActorRef and re-use it the guarantee will hold but if I perform an actorSelection each time it may not? Thanks and Merry Christmas, -Derek -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: http://akka.io/faq/ >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
