A Hands-On Guide to Akka with Scala

Learn how to implement fault tolerance by building a parent actor that supervises child actors, creates them with context.actorOf, and exchanges greet messages.

Explore the one-for-one fault tolerance strategy in Akka with Scala, where a supervising parent restarts only the failing child, handling arithmetic and legal argument exceptions, and contrast with one-for-all approach.

Apply all-for-one fault tolerance in akka with scala by restarting all child actors under a failing parent when an exception occurs.

Discover how the smallest mailbox pool distributes requests across multiple actors by assigning each new message to the least busy actor, improving throughput in distributed Akka applications.

Discover how a balancing pool redistributes work from busy actors to idle ones using a single mailbox, improving throughput and distribution across five actors.

Round robin routing distributes messages one by one to each actor in a circle, ensuring every actor receives a single message before the cycle repeats, illustrating fair, even distribution.

Learn how to use a broadcast pool in Akka with Scala to send a single message that distributes to all actors, ideal for push notifications and multi-device updates.

Explore scheduling in Akka with Scala by setting one-off and repeating tasks using the system scheduler, dispatcher, and duration library, enabling delayed and periodic actions.

Learn how to schedule actor messages in Akka with Scala using schedule once and schedule methods, sending message one and message two to an actor, with delayed and repeated triggers.

Learn to cancel schedules in Akka with the Cancelable module by storing the scheduled task in a cancelable variable and cancel it when i equals zero.
