C# Class Akka.Routing.ConsistentHashingPool

This class represents a Pool router that sends messages to a Routee determined using consistent-hashing. Please refer to ConsistentHashingRoutingLogic for more information on consistent hashing. Using Resizer with ConsistentHashingPool is potentially harmful, as hash ranges might change radically during live message processing. This router works best with fixed-sized pools or fixed number of routees per node in the event of clustered deployments.

Public Methods

Method	Description
ConsistentHashingPool ( Config config ) : System	Initializes a new instance of the ConsistentHashingPool class. 'virtual-nodes-factor' defaults to 0 (zero) if it is not defined in the provided configuration.
ConsistentHashingPool ( int nrOfInstances ) : System	Initializes a new instance of the ConsistentHashingPool class. A ConsistentHashingPool configured in this way uses the Pool.DefaultStrategy supervisor strategy.
ConsistentHashingPool ( int nrOfInstances, Akka.Routing.Resizer resizer, Akka.Actor.SupervisorStrategy supervisorStrategy, string routerDispatcher, bool usePoolDispatcher = false, int virtualNodesFactor, ConsistentHashMapping hashMapping = null ) : System	Initializes a new instance of the ConsistentHashingPool class.
CreateRouter ( ActorSystem system ) : Router	Creates a router that is responsible for routing messages to routees within the provided system.
ToSurrogate ( ActorSystem system ) : ISurrogate	Creates a surrogate representation of the current ConsistentHashingPool.
WithDispatcher ( string dispatcher ) : Akka.Routing.Pool	Creates a new ConsistentHashingPool router with a given dispatcher id. This method is immutable and returns a new instance of the router.
WithFallback ( Akka.Routing.RouterConfig routerConfig ) : Akka.Routing.RouterConfig	Configure the current router with an auxiliary router for routes that it does not know how to handle.
WithHashMapping ( ConsistentHashMapping mapping ) : ConsistentHashingPool	Creates a new ConsistentHashingPool router with a given ConsistentHashMapping. This method is immutable and returns a new instance of the router.
WithResizer ( Akka.Routing.Resizer resizer ) : Akka.Routing.Pool	Creates a new ConsistentHashingPool router with a given Resizer. This method is immutable and returns a new instance of the router. Using Resizer with ConsistentHashingPool is potentially harmful, as hash ranges might change radically during live message processing. This router works best with fixed-sized pools or fixed number of routees per node in the event of clustered deployments.
WithSupervisorStrategy ( Akka.Actor.SupervisorStrategy strategy ) : Akka.Routing.Pool	Creates a new ConsistentHashingPool router with a given SupervisorStrategy. This method is immutable and returns a new instance of the router.
WithVirtualNodesFactor ( int vnodes ) : ConsistentHashingPool	Creates a new ConsistentHashingPool router with a given VirtualNodesFactor. This method is immutable and returns a new instance of the router.

Method Details

ConsistentHashingPool() public method

Initializes a new instance of the ConsistentHashingPool class. 'virtual-nodes-factor' defaults to 0 (zero) if it is not defined in the provided configuration.

public ConsistentHashingPool ( Config config ) : System
config	Akka.Configuration.Config	The configuration used to configure the pool.
return	System

ConsistentHashingPool() public method

Initializes a new instance of the ConsistentHashingPool class. A ConsistentHashingPool configured in this way uses the Pool.DefaultStrategy supervisor strategy.

public ConsistentHashingPool ( int nrOfInstances ) : System
nrOfInstances	int	The initial number of routees in the pool.
return	System

ConsistentHashingPool() public method

Initializes a new instance of the ConsistentHashingPool class.

public ConsistentHashingPool ( int nrOfInstances, Akka.Routing.Resizer resizer, Akka.Actor.SupervisorStrategy supervisorStrategy, string routerDispatcher, bool usePoolDispatcher = false, int virtualNodesFactor, ConsistentHashMapping hashMapping = null ) : System
nrOfInstances	int	The initial number of routees in the pool.
resizer	Akka.Routing.Resizer	The resizer to use when dynamically allocating routees to the pool.
supervisorStrategy	Akka.Actor.SupervisorStrategy	The strategy to use when supervising the pool.
routerDispatcher	string	The dispatcher to use when passing messages to the routees.
usePoolDispatcher	bool	true to use the pool dispatcher; otherwise false.
virtualNodesFactor	int	The number of virtual nodes to use on the hash ring.
hashMapping	ConsistentHashMapping	The consistent hash mapping function to use on incoming messages.
return	System

CreateRouter() public method

Creates a router that is responsible for routing messages to routees within the provided system.

public CreateRouter ( ActorSystem system ) : Router
system	ActorSystem	The actor system that owns this router.
return	Router

ToSurrogate() public method

Creates a surrogate representation of the current ConsistentHashingPool.

public ToSurrogate ( ActorSystem system ) : ISurrogate
system	ActorSystem	The actor system that owns this router.
return	ISurrogate

WithDispatcher() public method

Creates a new ConsistentHashingPool router with a given dispatcher id. This method is immutable and returns a new instance of the router.

public WithDispatcher ( string dispatcher ) : Akka.Routing.Pool
dispatcher	string	The dispatcher id used to configure the new router.
return	Akka.Routing.Pool

WithFallback() public method

Configure the current router with an auxiliary router for routes that it does not know how to handle.

routerConfig
