    Commonly Used Patterns With Akka

    This package is used as a collection point for usage patterns which involve actors, futures, etc. but are loosely enough coupled to (multiple of) them to present them separately from the core implementation. Currently supported are:

    • ask: create a temporary one-off actor for receiving a reply to a message and complete a scala.concurrent.Future with it; returns said Future.
    • pipeTo: feed eventually computed value of a future to an akka.actor.ActorRef as a message.
    • pipeToSelection: feed eventually computed value of a future to an akka.actor.ActorSelection as a message.

    In Scala the recommended usage is to import the pattern from the package object:

    import akka.pattern.ask

ask(actor, message) // use it directly
actor ask message   // use it by implicit conversion

    For Java the patterns are available as static methods of the akka.pattern.Patterns class:

    import static akka.pattern.Patterns.ask;

ask(actor, message);

Type Members

  1. trait CircuitBreakerTelemetry extends AnyRef

    Service Provider Interface (SPI) for collecting metrics from Circuit Breaker.

    Service Provider Interface (SPI) for collecting metrics from Circuit Breaker.

    Implementations must include a single constructor with two arguments: Circuit Breaker id and ExtendedActorSystem. To setup your implementation, add a setting in your application.conf:

    akka.circuit-breaker.telemetry.implementations += com.example.MyMetrics
