C# Class Akka.Routing.ConsistentHashingRoutingLogic

This class contains logic used by a Router to route a message to a Routee determined using consistent-hashing. This process has the router select a routee based on a message's consistent hash key. There are 3 ways to define the key, which can be used individually or combined to form the key. The ConsistentHashMapping is tried first.
  1. You can define a ConsistentHashMapping or use WithHashMapping of the router to map incoming messages to their consistent hash key. This makes the decision transparent for the sender.
  2. Messages may implement IConsistentHashable. The hash key is part of the message and it's convenient to define it together with the message definition.
  3. The message can be wrapped in a ConsistentHashableEnvelope to define what data to use for the consistent hash key. The sender knows what key to use.

Méthodes publiques

Méthode Description
ConsistentHashingRoutingLogic ( ActorSystem system ) : System

Initializes a new instance of the ConsistentHashingRoutingLogic class. A ConsistentHashingRoutingLogic configured in this way uses the ConsistentHashingRouter.EmptyConsistentHashMapping as the hash mapping function with a virtual node factor of 0 (zero).

ConsistentHashingRoutingLogic ( ActorSystem system, int virtualNodesFactor, ConsistentHashMapping hashMapping ) : System

Initializes a new instance of the ConsistentHashingRoutingLogic class.
Select ( object message, Routee routees ) : Routee

Picks a Routee to receive the message.
WithHashMapping ( ConsistentHashMapping mapping ) : ConsistentHashingRoutingLogic

Creates a new ConsistentHashingRoutingLogic router logic with a given ConsistentHashMapping. This method is immutable and returns a new instance of the router.
