Re: [akka-user] How to Store the Message Object/Class to a database?
Hello Allen, have you had the chance to look into our akka-persistence http://doc.akka.io/docs/akka/2.3.3/scala/persistence.html module? Apps like you describe are very nicely modelled as events and “opposite events” if you want to “undo”. And direct answers to your questions: - path - the actor knows its full path via self.path ( see: http://doc.akka.io/api/akka/2.3.3/#akka.actor.ActorPath ) - storage - well, the entire interwebs somehow store objects in databases :-) One way to go around this is some object to relational / document mapper. But in Akka’s case I would recommend using akka-peristence :-) I hope this helps! -- Cheers, Konrad 'ktoso' Malawski hAkker - Typesafe, Inc http://scaladays.org -- Read the docs: http://akka.io/docs/ Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html 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.

[akka-user] How to Store the Message Object/Class to a database?
Hi, I encountered this problem while trying to write a program that has some sort of ability to undo its own action. I thought this data structure could do the trick: originalValue[String], changedValue[String], actorAddress[String], message[??]. Since Akka actor can send messages according to the URI, I imagine that I can create a RecoverActor that sends the original message with original value back to that Actor. Easy. However, I run into two problems shortly after. First one should be easy and is caused due to my inexperience with Akka framework: how does an actor know its own absolute URI? Second problem, all messages in Akka are either classes or objects. It's almost impossible to store such data type into a database and I even tried Redis (thought it could somehow magically allow me to do so). How can I possibly achieve this undo action? I'm using Scala with Akka btw. Any idea? -- Read the docs: http://akka.io/docs/ Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html 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.
