It ties into the central idea that actor systems form +intrinsic supervision hierarchies as well as that communication between actors +is transparent with respect to their placement across multiple network nodes. + +What is an Actor Reference? +--------------------------- + +An actor reference is a subtype of :class:`ActorRef`, whose foremost purpose is +to support sending messages to the actor it represents. Each actor has access +to its canonical (local) reference through the :meth:`self` field; this +reference is also included as sender reference by default for all messages sent +to other actors. Conversely, during message processing the actor has access to +a reference representing the sender of the current message through the +:meth:`sender` field. + +There are several different types of actor references that are supported +depending on the configuration of the actor system: + +- Purely local actor references are used by actor systems which are not + configured to support networking functions. These actor references cannot + ever be sent across a network connection while retaining their functionality. +- Local actor references when remoting is enabled are used by actor systems + which support networking functions for those references which represent + actors within the same JVM. In order to be recognizable also when sent to + other network nodes, these references include protocol and remote addressing + information. +- There is a subtype of local actor references which is used for routers (i.e. + actors mixing in the :class:`Router` trait). Its logical structure is the + same as for the aforementioned local references, but sending a message to + them dispatches to one of their children directly instead. +- Remote actor references represent actors which are reachable using remote + communication, i.e. sending messages to them will serialize the messages + transparently and send them to the other JVM. +- There are several special types of actor references which behave like local + actor references for all practical purposes: + + - :class:`AskActorRef` is the special representation of a :meth:`Promise` for + the purpose of being completed by the response from an actor; it is created + by the :meth:`ActorRef.ask` invocation. + - :class:`DeadLetterActorRef` is the default implementation of the dead + letters service, where all messages are re-routed whose targets are shut + down or non-existent. + +- And then there are some one-off internal implementations which you should + never really see: + + - There is an actor reference which does not represent an actor but acts only + as a pseudo-supervisor for the root guardian, we call it “the one who walks + the bubbles of space-time”. + - The first logging service started before actually firing up actor creation + facilities is a fake actor reference which accepts log events and prints + them directly to standard output; it is :class:`Logging.StandardOutLogger`. + +- **(Future Extension)** Cluster actor references represent clustered actor + services which may be replicated, migrated or load-balanced across multiple + cluster nodes. As such they are virtual names which the cluster service + translates into local or remote actor references as appropriate. + +What is an Actor Path? +---------------------- + +Since actors are created in a strictly hierarchical fashion, there exists a +unique sequence of actor names given by recursively following the supervision +links between child and parent down towards the root of the actor system. This +sequence can be seen as enclosing folders in a file system, hence we adopted +the name “path” to refer to it. As in some real file-systems there also are +“symbolic links”, i.e. one actor may be reachable using more than one path, +where all but one involve some translation which decouples part of the path +from the actor’s actual supervision ancestor line; these specialities are +described in the sub-sections to follow. + +Each actor path has an address component, describing the protocol and location +by which the corresponding actor is reachable, followed by the names of the +actors in the hierarchy from the root up. Examples are:: + + "akka://my-system/app/service-a/worker1" // purely local + "akka://my-system@serv.example.com:5678/app/service-b" // local or remote + "cluster://my-cluster/service-c" // clustered (Future Extension) + +Here, ``akka`` is the default remote protocol for the 2.0 release, and others +are pluggable. The interpretation of the host & port part (i.e. +``serv.example.com:5678`` in the example) depends on the transport mechanism +used, but it should abide by the URI structural rules. + +Logical Actor Paths +^^^^^^^^^^^^^^^^^^^ + +The unique path obtained by following the parental supervision links towards +the root guardian is called the logical actor path. This path matches exactly +the creation ancestry of an actor, so it is completely deterministic as soon as +the actor system’s remoting configuration (and with it the address component of +the path) is set. + +Physical Actor Paths +^^^^^^^^^^^^^^^^^^^^ + +While the logical actor path describes the functional location within one actor +system, configuration-based transparent remoting means that an actor may be +created on a different network host as its parent, i.e. within a different +actor system. In this case, following the actor path from the root guardian up +entails traversing the network, which is a costly operation. Therefore, each +actor also has a physical path, starting at the root guardian of the actor +system where the actual actor object resides. Using this path as sender +reference when querying other actors will let them reply directly to this +actor, minimizing delays incurred by routing. + +One important aspect is that a physical actor path never spans multiple actor +systems or JVMs. This means that the logical path (supervision hierarchy) and +the physical path (actor deployment) of an actor may diverge if one of its +ancestors is remotely supervised. + +Virtual Actor Paths **(Future Extension)** +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +In order to be able to replicate and migrate actors across a cluster of Akka +nodes, another level of indirection has to be introduced. The cluster component +therefore provides a translation from virtual paths to physical paths which may +change in reaction to node failures, cluster rebalancing, etc. + +*This area is still under active development, expect updates in this section +for the 2.1 release.* + +How are Actor References obtained? +---------------------------------- + +There are two general categories to how actor references may be obtained: by +creating actors or by looking them up, where the latter functionality comes in +the two flavours of creating actor references from concrete actor paths and +querying the logical actor hierarchy. + +*While local and remote actor references and their paths work in the same way +concerning the facilities mentioned below, the exact semantics of clustered +actor references and their paths—while certainly as similar as possible—may +differ in certain aspects, owing to the virtual nature of those paths. Expect +updates for the 2.1 release.* + +Creating Actors +^^^^^^^^^^^^^^^ + +An actor system is typically started by creating actors above the guardian +actor using the :meth:`ActorSystem.actorOf` method and then using +:meth:`ActorContext.actorOf` from within the created actors to spawn the actor +tree. These methods return a reference to the newly created actors. Each actor +has direct access to references for its parent, itself and its children. These +references may be sent within messages to other actors, enabling those to reply +directly. + +Looking up Actors by Concrete Path +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +In addition, actor references may be looked up using the +:meth:`ActorSystem.actorFor` method, which returns an (unverified) local, +remote or clustered actor reference. Sending messages to such a reference or +attempting to observe its livelyhood will traverse the actor hierarchy of the +actor system from top to bottom by passing messages from parent to child until +either the target is reached or failure is certain, i.e. a name in the path +does not exist (in practice this process will be optimized using caches, but it +still has added cost compared to using the physical actor path, can for example +to obtained from the sender reference included in replies from that actor). The +messages passed are handled automatically by Akka, so this process is not +visible to client code. + +Absolute vs. Relative Paths +``````````````````````````` + +In addition to :meth:`ActorSystem.actorFor` there is also +:meth:`ActorContext.actorFor`, which is available inside any actor as +``context.actorFor``. This yields an actor reference much like its twin on +:class:`ActorSystem`, but instead of looking up the path starting from the root +of the actor tree it starts out on the current actor. Path elements consisting +of two dots (``".."``) may be used to access the parent actor. You can for +example send a message to a specific sibling:: + + context.actorFor("../brother") ! msg + +Querying the Logical Actor Hierarchy +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Since the actor system forms a file-system like hierarchy, matching on paths is +possible in the same was as supported by Unix shells: you may replace (parts +of) path element names with wildcards (`"*"` and `"?"`) to formulate a +selection which may match zero or more actual actors. Because the result is not +a single actor reference, it has a different type :class:`ActorSelection` and +does not support the full set of operations an :class:`ActorRef` does. +Selections may be formulated using the :meth:`ActorSystem.actorSelection` and +:meth:`ActorContext.actorSelection` methods and do support sending messages:: + + context.actorSelection("../*") ! msg + +will send `msg` to all siblings including the current actor. As for references +obtained using `actorFor`, a traversal of the supervision hierarchy is done in +order to perform the message send. As the exact set of actors which match a +selection may change even while a message is making its way to the recipients, +it is not possible to watch a selection for liveliness changes. In order to do +that, resolve the uncertainty by sending a request and gathering all answers, +extracting the sender references, and then watch all discovered concrete +actors. This scheme of resolving a selection may be improved upon in a future +release. + +The Interplay with Remote Deployment +------------------------------------ + +When an actor creates a child, the actor system’s deployer will decide whether +the new actor resides in the same JVM or on another node. In the second case, +creation of the actor will be triggered via a network connection to happen in a +different JVM and consequently within a different actor system. The remote +system will place the new actor below a special path reserved for this purpose +and the supervisor of the new actor will be a remote actor reference +(representing that actor which triggered its creation). In this case, +:meth:`parent` (the supervisor reference) and :meth:`context.path.parent` (the +parent node in the actor’s path) do not represent the same actor. However, +looking up the child’s name within the supervisor will find it on the remote +node, preserving logical structure e.g. when sending to an unresolved actor +reference. + +The Interplay with Clustering **(Future Extension)** +---------------------------------------------------- + +*This section is subject to change!* + +When creating a scaled-out actor subtree, a cluster name is created for a +routed actor reference, where sending to this reference will send to one (or +more) of the actual actors created in the cluster. In order for those actors to +be able to query other actors while processing their messages, their sender +reference must be unique for each of the replicas, which means that physical +paths will be used as ``self`` references for these instances. In the case +of replication for achieving fault-tolerance the opposite is required: the +``self`` reference will be a virtual (cluster) path so that in case of +migration or fail-over communication is resumed with the fresh instance. + +What is the Address part used for? +---------------------------------- + +When sending an actor reference across the network, it is represented by its +path. Hence, the path must fully encode all information necessary to send +messages to the underlying actor. This is achieved by encoding protocol, host +and port in the address part of the path string. When an actor system receives +an actor path from a remote node, it checks whether that path’s address matches +the address of this actor system, in which case it will be resolved to the +actor’s local reference. Otherwise, it will be represented by a remote actor +reference. + +Special Paths used by Akka +-------------------------- + +At the root of the path hierarchy resides the root guardian above which all +other actors are found. The next level consists of the following: + +- ``"/user"`` is the guardian actor for all user-created top-level actors; + actors created using :meth:`ActorSystem.actorOf` are found at the next level. +- ``"/system"`` is the guardian actor for all system-created top-level actors, + e.g. logging listeners or actors automatically deployed by configuration at + the start of the actor system. +- ``"/null"`` is the dead letter actor, which is where all messages sent to + stopped or non-existing actors are re-routed. +- ``"/temp"`` is the guardian for all short-lived system-created actors, e.g. + those which are used in the implementation of :meth:`ActorRef.ask`. +- ``"/remote"`` is an artificial path below which all actors reside whose + supervisors are remote actor references +- ``"/service"`` is an artificial path below which actors can be presented by + means of configuration, i.e. deployed at system start-up or just-in-time + (triggered by look-up) or “mounting” other actors by path—local or remote—to + give them logical names. + diff --git a/akka-docs/general/index.rst b/akka-docs/general/index.rst index 83e9684bb4..687892b177 100644 --- a/akka-docs/general/index.rst +++ b/akka-docs/general/index.rst @@ -8,5 +8,6 @@ General configuration event-handler slf4j + addressing supervision guaranteed-delivery diff --git a/akka-durable-mailboxes/akka-mailboxes-common/src/main/scala/akka/actor/mailbox/DurableMailbox.scala b/akka-durable-mailboxes/akka-mailboxes-common/src/main/scala/akka/actor/mailbox/DurableMailbox.scala index b5d832d443..7bb01a06f0 100644 --- a/akka-durable-mailboxes/akka-mailboxes-common/src/main/scala/akka/actor/mailbox/DurableMailbox.scala +++ b/akka-durable-mailboxes/akka-mailboxes-common/src/main/scala/akka/actor/mailbox/DurableMailbox.scala @@ -41,7 +41,7 @@ abstract class DurableMailbox(owner: ActorCell) extends Mailbox(owner) with Defa def system = owner.system def ownerPath = owner.self.path -
