Type Members

  1. trait ConsistentHashMapper extends AnyRef

    JAVA API Mapping from message to the data to use for the consistent hash key.

    JAVA API Mapping from message to the data to use for the consistent hash key. Note that it's not the hash that is to be returned, but the data to be hashed.

    May return null to indicate that the message is not handled by this mapping.

    If returning an Array[Byte] or String it will be used as is, otherwise the configured akka.serialization.Serializer will be applied to the returned data.

  2. type ConsistentHashMapping = PartialFunction[Any, Any]

    Partial function from message to the data to use for the consistent hash key.

    Partial function from message to the data to use for the consistent hash key. Note that it's not the hash that is to be returned, but the data to be hashed.

    If returning an Array[Byte] or String it will be used as is, otherwise the configured akka.serialization.Serializer will be applied to the returned data.

  3. trait ConsistentHashable extends AnyRef

    If you don't define the hashMapping when constructing the akka.routing.ConsistentHashingRouter the messages need to implement this interface to define what data to use for the consistent hash key.

    If you don't define the hashMapping when constructing the akka.routing.ConsistentHashingRouter the messages need to implement this interface to define what data to use for the consistent hash key. Note that it's not the hash, but the data to be hashed.

    If returning an Array[Byte] or String it will be used as is, otherwise the configured akka.serialization.Serializer will be applied to the returned data.

    If messages can't implement this interface themselves, it's possible to wrap the messages in akka.routing.ConsistentHashingRouter.ConsistentHashableEnvelope, or use akka.routing.ConsistentHashingRouter.ConsistentHashableEnvelope

  4. final case class ConsistentHashableEnvelope(message: Any, hashKey: Any) extends ConsistentHashable with RouterEnvelope with WrappedMessage with Product with Serializable

    If you don't define the hashMapping when constructing the akka.routing.ConsistentHashingRouter and messages can't implement akka.routing.ConsistentHashingRouter.ConsistentHashable themselves they can we wrapped by this envelope instead.

    If you don't define the hashMapping when constructing the akka.routing.ConsistentHashingRouter and messages can't implement akka.routing.ConsistentHashingRouter.ConsistentHashable themselves they can we wrapped by this envelope instead. The router will only send the wrapped message to the destination, i.e. the envelope will be stripped off.
