I have a project that is using Akka Actors in scala, and I'm running into
some issues regarding the actors that do processing and send the results
back to the sender.
To better explain, here is the workflow of my project:
- Commander send msg to Poller
- Poller sends SuccessMessage(self, List[String]) to Commander
- Commander sends List[String] to Processor
- Processor sends SuccessMessage(self, File) to Commander
- Commander sends File to Uploader
- Uploader sends SuccessMessage(self, Boolean) to Commander
- and so on.
Essentially, I have two questions:
Right now, I wrap everything that is returned from an actor back to the
Commander (supervisor) in a SuccessMessage. Is this the best way of doing
it, or is there another way to handle many different types of return?
The SuccessMessage will also have a "payload". I am debating between using
generics for the payload type, or just making it an Option[Any] and then
doing a lot of casting on the commander side, before sending it to any
actor (poller, processor, etc.). I know that in Java akka actors just cast
Object; would I have to do the same?
Thanks for your help!! Just wondering if there's a cooler way of doing
things...
