Welcome Akka Typed - Prabhat Kashyap
Akka has become a very successful platform for building reactive systems. At its core, the Akka-actor module implements the actor model. Surprisingly enough, although Scala and Java are type-safe languages, Akka actors are untyped. This means that we can only handle specific ones - the compiler is not ready to help us. This pdf will walk through how to add the type parameter to the ActorRef and reduces the runtime error.

- 3. 3 My name isPrabhat Kashyap and I am a backend Scala developer, currently living in New Delhi, India. I have a master’s degree in computer application and currently working with Knoldus Inc., which is world’s largest pure-play Scala Spark services company as a Senior Software Consultant. I started my career in software development two and a half years ago and since then working on Scala. I am part of the development team responsible for developing the application of different domain using functional approach. I also possess the knowledge of Akka, Apache Kafka, Carbondata and Blockchains.

- 4. 4 ❑ A opensource project started by Jonas Bonér in 2009. ❑ Akka’s use of the actor model provides a level of abstraction that makes it easier to write correct concurrent, parallel and distributed systems. ❑ Consequently, organizations building distributed systems with demanding requirements encounter challenges that cannot fully be solved with a traditional object-oriented programming (OOP) model, but that can benefit from the actor model. What is Akka
- 5. 5 ❑ The actormodel was proposed decades ago by Carl Hewitt as a way to handle parallel processing in a high performance network. ❑ Send a finite number of messages to other actors. ❑ Create a finite number of new actors. ❑ Designate the behavior to be used for the next message it receives. What is Actor?
- 6. 6 ❑ An actorsystem manages the resources it is configured to use in order to run the actors which it contains. ❑ The actor system as a collaborating ensemble of actors is the natural unit for managing shared facilities like scheduling services, configuration, logging, etc. What is Actor System?
