+* `Akka Consumer Actors: New Features and Best Practices `_ +* `Akka Producer Actors: New Features and Best Practices `_ + + +Introduction +============ + +The akka-camel module allows actors, untyped actors, and typed actors to receive +and send messages over a great variety of protocols and APIs. This section gives +a brief overview of the general ideas behind the akka-camel module, the +remaining sections go into the details. In addition to the native Scala and Java +actor API, actors can now exchange messages with other systems over large number +of protocols and APIs such as HTTP, SOAP, TCP, FTP, SMTP or JMS, to mention a +few. At the moment, approximately 80 protocols and APIs are supported. + +The akka-camel module is based on `Apache Camel`_, a powerful and leight-weight +integration framework for the JVM. For an introduction to Apache Camel you may +want to read this `Apache Camel article`_. Camel comes with a +large number of `components`_ that provide bindings to different protocols and +APIs. The `camel-extra`_ project provides further components. + +.. _Apache Camel: http://camel.apache.org/ +.. _Apache Camel article: http://architects.dzone.com/articles/apache-camel-integration +.. _components: http://camel.apache.org/components.html +.. _camel-extra: http://code.google.com/p/camel-extra/ + +Usage of Camel's integration components in Akka is essentially a +one-liner. Here's an example. + +.. code-block:: scala + + import akka.actor.Actor + import akka.actor.Actor._ + import akka.camel.{Message, Consumer} + + class MyActor extends Actor with Consumer { + def endpointUri = "mina:tcp://localhost:6200?textline=true" + + def receive = { + case msg: Message => { /* ... */} + case _ => { /* ... */} + } + } + + // start and expose actor via tcp + val myActor = actorOf[MyActor].start + +The above example exposes an actor over a tcp endpoint on port 6200 via Apache +Camel's `Mina component`_. The actor implements the endpointUri method to define +an endpoint from which it can receive messages. After starting the actor, tcp +clients can immediately send messages to and receive responses from that +actor. If the message exchange should go over HTTP (via Camel's `Jetty +component`_), only the actor's endpointUri method must be changed. + +.. _Mina component: http://camel.apache.org/mina.html +.. _Jetty component: http://camel.apache.org/jetty.html + +.. code-block:: scala + + class MyActor extends Actor with Consumer { + def endpointUri = "jetty:http://localhost:8877/example" + + def receive = { + case msg: Message => { /* ... */} + case _ => { /* ... */} + } + } + +Actors can also trigger message exchanges with external systems i.e. produce to +Camel endpoints. + +.. code-block:: scala + + import akka.actor.Actor + import akka.camel.{Producer, Oneway} + + class MyActor extends Actor with Producer with Oneway { + def endpointUri = "jms:queue:example" + } + +In the above example, any message sent to this actor will be added (produced) to +the example JMS queue. Producer actors may choose from the same set of Camel +components as Consumer actors do. + +The number of Camel components is constantly increasing. The akka-camel module +can support these in a plug-and-play manner. Just add them to your application's +classpath, define a component-specific endpoint URI and use it to exchange +messages over the component-specific protocols or APIs. This is possible because +Camel components bind protocol-specific message formats to a Camel-specific +`normalized message format`__. The normalized message format hides +protocol-specific details from Akka and makes it therefore very easy to support +a large number of protocols through a uniform Camel component interface. The +akka-camel module further converts mutable Camel messages into `immutable +representations`__ which are used by Consumer and Producer actors for pattern +matching, transformation, serialization or storage, for example. + +__ https://svn.apache.org/repos/asf/camel/trunk/camel-core/src/main/java/org/apache/camel/Message.java +__ http://github.com/jboner/akka-modules/blob/v0.8/akka-camel/src/main/scala/akka/Message.scala#L17 + + +Dependencies +============ + +Akka's Camel Integration consists of two modules + +* akka-camel - this module depends on akka-actor and camel-core (+ transitive + dependencies) and implements the Camel integration for (untyped) actors + +* akka-camel-typed - this module depends on akka-typed-actor and akka-camel (+ + transitive dependencies) and implements the Camel integration for typed actors + +The akka-camel-typed module is optional.

For example, the following actor class (Consumer1) implements the +endpointUri method, which is declared in the Consumer trait, in order to receive +messages from the ``file:data/input/actor`` Camel endpoint. Untyped actors +(Java) need to extend the abstract UntypedConsumerActor class and implement the +getEndpointUri() and onReceive(Object) methods. + +.. _Consumer: http://github.com/jboner/akka-modules/blob/master/akka-camel/src/main/scala/akka/camel/Consumer.scala + +**Scala** + +.. code-block:: scala + + import akka.actor.Actor + import akka.camel.{Message, Consumer} + + class Consumer1 extends Actor with Consumer { + def endpointUri = "file:data/input/actor" + + def receive = { + case msg: Message => println("received %s" format msg.bodyAs[String]) + } + } + +**Java** + +.. code-block:: java + + import akka.camel.Message; + import akka.camel.UntypedConsumerActor; + + public class Consumer1 extends UntypedConsumerActor { + public String getEndpointUri() { + return "file:data/input/actor"; + } + + public void onReceive(Object message) { + Message msg = (Message)message; + String body = msg.getBodyAs(String.class); + System.out.println(String.format("received %s", body)) + } + } + +Whenever a file is put into the data/input/actor directory, its content is +picked up by the Camel `file component`_ and sent as message to the +actor.

The actor sends a response by using the +self.reply method (Scala). For returning a message body and headers to the HTTP +client the response type should be `Message`_. For any other response type, a +new Message object is created by akka-camel with the actor response as message +body. + +.. _Message: http://github.com/jboner/akka-modules/blob/master/akka-camel/src/main/scala/akka/camel/Message.scala + + +Typed actors +------------ + +Typed actors can also receive messages from Camel endpoints. In contrast to +(untyped) actors, which only implement a single receive or onReceive method, a +typed actor may define several (message processing) methods, each of which can +receive messages from a different Camel endpoint. For a typed actor method to be +exposed as Camel endpoint it must be annotated with the `@consume +annotation`_. For example, the following typed consumer actor defines two +methods, foo and bar. + +.. _@consume annotation: http://github.com/jboner/akka-modules/blob/master/akka-camel/src/main/java/akka/camel/consume.java + +**Scala** + +.. code-block:: scala + + import org.apache.camel.{Body, Header} + import akka.actor.TypedActor + import akka.camel.consume + + trait TypedConsumer1 { + @consume("file:data/input/foo") + def foo(body: String): Unit + + @consume("jetty:http://localhost:8877/camel/bar") + def bar(@Body body: String, @Header("X-Whatever") header: String): String + } + + class TypedConsumer1Impl extends TypedActor with TypedConsumer1 { + def foo(body: String) = println("Received message: %s" format body) + def bar(body: String, header: String) = "body=%s header=%s" format (body, header) + } + +**Java** + +.. code-block:: java + + import org.apache.camel.Body; + import org.apache.camel.Header; + import akka.actor.TypedActor; + import akka.camel.consume; + + public interface TypedConsumer1 { + @consume("file:data/input/foo") + public void foo(String body); + + @consume("jetty:http://localhost:8877/camel/bar") + public String bar(@Body String body, @Header("X-Whatever") String header); + } + + public class TypedConsumer1Impl extends TypedActor implements TypedConsumer1 { + public void foo(String body) { + System.out.println(String.format("Received message: ", body)); + } + + public String bar(String body, String header) { + return String.format("body=%s header=%s", body, header); + } + } + +The foo method can be invoked by placing a file in the data/input/foo +directory. Camel picks up the file from this directory and akka-camel invokes +foo with the file content as argument (converted to a String). Camel +automatically tries to convert messages to appropriate types as defined by the +method parameter(s). The conversion rules are described in detail on the +following pages: + +* `Bean integration `_ +* `Bean binding `_ +* `Parameter binding `_ + +The bar method can be invoked by POSTing a message to +http://localhost:8877/camel/bar. Here, parameter binding annotations are used to +tell Camel how to extract data from the HTTP message. The @Body annotation binds +the HTTP request body to the first parameter, the @Header annotation binds the +X-Whatever header to the second parameter. The return value is sent as HTTP +response message body to the client. + +Parameter binding annotations must be placed on the interface, the @consume +annotation can also be placed on the methods in the implementation class. + + +.. _camel-publishing: + +Consumer publishing +------------------- + +Actors (untyped) +^^^^^^^^^^^^^^^^ + +Publishing a consumer actor at its Camel endpoint occurs when the actor is +started.

The reply message can be a +Message (or any object which is then internally converted to a Message) on +success, and a Failure message on failure. + +With in-only message exchanges, by default, an exchange is done when a message +is added to the consumer actor's mailbox. Any failure or exception that occurs +during processing of that message by the consumer actor cannot be reported back +to the endpoint in this case. To allow consumer actors to positively or +negatively acknowledge the receipt of a message from an in-only message +exchange, they need to override the ``autoack`` (Scala) or ``isAutoack`` (Java) +method to return false. In this case, consumer actors must reply either with a +special Ack message (positive acknowledgement) or a Failure (negative +acknowledgement). + +**Scala** + +.. code-block:: scala + + import akka.camel.{Ack, Failure} + // ... other imports omitted + + class Consumer3 extends Actor with Consumer { + override def autoack = false + + def endpointUri = "jms:queue:test" + + def receive = { + // ... + self.reply(Ack) // on success + // ... + self.reply(Failure(...)) // on failure + } + } + +**Java** + +.. code-block:: java + + import akka.camel.Failure + import static akka.camel.Ack.ack; + // ... other imports omitted + + public class Consumer3 extends UntypedConsumerActor { + + public String getEndpointUri() { + return "jms:queue:test"; + } + + public boolean isAutoack() { + return false; + } + + public void onReceive(Object message) { + // ... + getContext().replyUnsafe(ack()) // on success + // ... + val e: Exception = ... + getContext().replyUnsafe(new Failure(e)) // on failure + } + } + + +.. _camel-blocking-exchanges: + +Blocking exchanges +------------------ + +By default, message exchanges between a Camel endpoint and a consumer actor are +non-blocking because, internally, the ! (bang) operator is used to commicate +with the actor. The route to the actor does not block waiting for a reply. The +reply is sent asynchronously (see also :ref:`camel-asynchronous-routing`). +Consumer actors however can be configured to make this interaction blocking. + +**Scala** + +.. code-block:: scala + + class ExampleConsumer extends Actor with Consumer { + override def blocking = true + + def endpointUri = ... + def receive = { + // ... + } + } + +**Java** + +.. code-block:: java + + public class ExampleConsumer extends UntypedConsumerActor { + + public boolean isBlocking() { + return true; + } + + public String getEndpointUri() { + // ... + } + + public void onReceive(Object message) { + // ... + } + } + +In this case, the ``!!`` (bangbang) operator is used internally to communicate +with the actor which blocks a thread until the consumer sends a response or +throws an exception within receive. Although it may decrease scalability, this +setting can simplify error handling (see `this article`_) or allows timeout +configurations on actor-level (see :ref:`camel-timeout`). + +.. _this article: http://krasserm.blogspot.com/2011/02/akka-consumer-actors-new-features-and.html + + +.. _camel-timeout: + +Consumer timeout +---------------- + +Endpoints that support two-way communications need to wait for a response from +an (untyped) actor or typed actor before returning it to the initiating client. +For some endpoint types, timeout values can be defined in an endpoint-specific +way which is described in the documentation of the individual `Camel +components`_. Another option is to configure timeouts on the level of consumer +actors and typed consumer actors. + +.. _Camel components: http://camel.apache.org/components.html + + +Typed actors +^^^^^^^^^^^^ + +For typed actors, timeout values for method calls that return a result can be +set when the typed actor is created. In the following example, the timeout is +set to 20 seconds (default is 5 seconds). + +**Scala** + +.. code-block:: scala + + import akka.actor.TypedActor + + val consumer = TypedActor.newInstance(classOf[TypedConsumer1], classOf[TypedConumer1Impl], 20000 /* 20 seconds */) + +**Java** + +.. code-block:: java + + import akka.actor.TypedActor; + + TypedConsumer1 consumer = TypedActor.newInstance(TypedConsumer1.class, TypedConumer1Impl.class, 20000 /* 20 seconds */); + + +Actors (untyped) +^^^^^^^^^^^^^^^^ + +Two-way communications between a Camel endpoint and an (untyped) actor are +initiated by sending the request message to the actor with the ``!`` (bang) +operator and the actor replies to the endpoint when the response is ready. In +order to support timeouts on actor-level, endpoints need to send the request +message with the ``!!`` (bangbang) operator for which a timeout value is +applicable. This can be achieved by overriding the Consumer.blocking method to +return true. + +**Scala** + +.. code-block:: scala + + class Consumer2 extends Actor with Consumer { + self.timeout = 20000 // timeout set to 20 seconds + + override def blocking = true + + def endpointUri = "direct:example" + + def receive = { + // ... + } + } + +**Java** + +.. code-block:: java + + public class Consumer2 extends UntypedConsumerActor { + + public Consumer2() { + getContext().setTimeout(20000); // timeout set to 20 seconds + } + + public String getEndpointUri() { + return "direct:example"; + } + + public boolean isBlocking() { + return true; + } + + public void onReceive(Object message) { + // ... + } + } + +This is a valid approach for all endpoint types that do not "natively" support +asynchronous two-way message exchanges. For all other endpoint types (like +`Jetty`_ endpoints) is it not recommended to switch to blocking mode but rather +to configure timeouts in an endpoint-specific way (see +also :ref:`camel-asynchronous-routing`). + + +Remote consumers +---------------- + +Actors (untyped) +^^^^^^^^^^^^^^^^ + +Publishing of remote consumer actors is always done on the server side, local +proxies are never published. Hence the CamelService must be started on the +remote node. For example, to publish an (untyped) actor on a remote node at +endpoint URI ``jetty:http://localhost:6644/remote-actor-1``, define the +following consumer actor class. + +**Scala** + +.. code-block:: scala + + import akka.actor.Actor + import akka.annotation.consume + import akka.camel.Consumer + + class RemoteActor1 extends Actor with Consumer { + def endpointUri = "jetty:http://localhost:6644/remote-actor-1" + + protected def receive = { + case msg => self.reply("response from remote actor 1") + } + } + +**Java** + +.. code-block:: java + + import akka.camel.UntypedConsumerActor; + + public class RemoteActor1 extends UntypedConsumerActor { + public String getEndpointUri() { + return "jetty:http://localhost:6644/remote-actor-1"; + } + + public void onReceive(Object message) { + getContext().replySafe("response from remote actor 1"); + } + } + +On the remote node, start a `CamelService`_, start a remote server, create the +actor and register it at the remote server. + +.. _CamelService: http://github.com/jboner/akka-modules/blob/master/akka-camel/src/main/scala/akka/camel/CamelService.scala + +**Scala** + +.. code-block:: scala + + import akka.camel.CamelServiceManager._ + import akka.actor.Actor._ + import akka.actor.ActorRef + + // ... + startCamelService + + val consumer = val consumer = actorOf[RemoteActor1] + + remote.start("localhost", 7777) + remote.register(consumer) // register and start remote consumer + // ... + +**Java** + +.. code-block:: java + + import akka.camel.CamelServiceManager; + import static akka.actor.Actors.*; + + // ... + CamelServiceManager.startCamelService(); + + ActorRef actor = actorOf(RemoteActor1.class); + + remote().start("localhost", 7777); + remote().register(actor); // register and start remote consumer + // ... + +Explicitly starting a CamelService can be omitted when Akka is running in Kernel +mode, for example (see also :ref:`camel-configuration`). + + +Typed actors +^^^^^^^^^^^^ + +Remote typed consumer actors can be registered with one of the +``registerTyped*`` methods on the remote server.

Otherwise, +just start a CamelService as described for consumer +actors: :ref:`camel-consumers-and-camel-service`. + + +Producer trait +-------------- + +Actors (untyped) +^^^^^^^^^^^^^^^^ + +For sending messages to Camel endpoints, actors + +* written in Scala need to mixin the `Producer`_ trait and implement the + endpointUri method. + +* written in Java need to extend the abstract UntypedProducerActor class and + implement the getEndpointUri() method. By extending the UntypedProducerActor + class, untyped actors (Java) inherit the behaviour of the Producer trait. + +.. _Producer: http://github.com/jboner/akka-modules/blob/master/akka-camel/src/main/scala/akka/camel/Producer.scala + +**Scala** + +.. code-block:: scala + + import akka.actor.Actor + import akka.camel.Producer + + class Producer1 extends Actor with Producer { + def endpointUri = "http://localhost:8080/news" + } + +**Java** + +.. code-block:: java + + import akka.camel.UntypedProducerActor; + + public class Producer1 extends UntypedProducerActor { + public String getEndpointUri() { + return "http://localhost:8080/news"; + } + } + +Producer1 inherits a default implementation of the receive method from the +Producer trait. To customize a producer actor's default behavior it is +recommended to override the Producer.receiveBeforeProduce and +Producer.receiveAfterProduce methods. This is explained later in more detail. +Actors should not override the default Producer.receive method. + +Any message sent to a Producer actor (or UntypedProducerActor) will be sent to +the associated Camel endpoint, in the above example to +``http://localhost:8080/news``. Response messages (if supported by the +configured endpoint) will, by default, be returned to the original sender. The +following example uses the ``!!`` operator (Scala) to send a message to a +Producer actor and waits for a response. In Java, the sendRequestReply method is +used. + +**Scala** + +.. code-block:: scala + + import akka.actor.Actor._ + import akka.actor.ActorRef + + val producer = actorOf[Producer1].start + val response = producer !!

It was the application's +responsibility to define the route and add it to the current CamelContext. This +section explains a more conventient way to define custom routes: akka-camel is +still setting up the routes to consumer actors (and adds these routes to the +current CamelContext) but applications can define extensions to these routes. +Extensions can be defined with Camel's `Java DSL`_ or `Scala DSL`_. For example, +an extension could be a custom error handler that redelivers messages from an +endpoint to an actor's bounded mailbox when the mailbox was full. + +.. _Java DSL: http://camel.apache.org/dsl.html +.. _Scala DSL: http://camel.apache.org/scala-dsl.html + +The following examples demonstrate how to extend a route to a consumer actor for +handling exceptions thrown by that actor. To simplify the example, we configure +:ref:`camel-blocking-exchanges` which reports any exception, that is thrown by +receive, directly back to the Camel route. One could also report exceptions +asynchronously using a Failure reply (see also `this article`__) but we'll do it +differently here. + +__ http://krasserm.blogspot.com/2011/02/akka-consumer-actors-new-features-and.html + + +Actors (untyped) +^^^^^^^^^^^^^^^^ + +**Scala** + +.. code-block:: scala + + import akka.actor.Actor + import akka.camel.Consumer + + import org.apache.camel.builder.Builder + import org.apache.camel.model.RouteDefinition + + class ErrorHandlingConsumer extends Actor with Consumer { + def endpointUri = "direct:error-handler-test" + + // Needed to propagate exception back to caller + override def blocking = true + + onRouteDefinition {rd: RouteDefinition => + // Catch any exception and handle it by returning the exception message as response + rd.onException(classOf[Exception]).handled(true).transform(Builder.exceptionMessage).end + } + + protected def receive = { + case msg: Message => throw new Exception("error: %s" format msg.body) + } + } + +**Java** + +.. code-block:: java + + import akka.camel.UntypedConsumerActor; + + import org.apache.camel.builder.Builder; + import org.apache.camel.model.ProcessorDefinition; + import org.apache.camel.model.RouteDefinition; + + public class SampleErrorHandlingConsumer extends UntypedConsumerActor { + + public String getEndpointUri() { + return "direct:error-handler-test"; + } + + // Needed to propagate exception back to caller + public boolean isBlocking() { + return true; + } + + public void preStart() { + onRouteDefinition(new RouteDefinitionHandler() { + public ProcessorDefinition onRouteDefinition(RouteDefinition rd) { + // Catch any exception and handle it by returning the exception message as response + return rd.onException(Exception.class).handled(true).transform(Builder.exceptionMessage()).end(); + } + }); + } + + public void onReceive(Object message) throws Exception { + Message msg = (Message)message; + String body = msg.getBodyAs(String.class); + throw new Exception(String.format("error: %s", body)); + } + + } + + + +For (untyped) actors, consumer route extensions are defined by calling the +onRouteDefinition method with a route definition handler. In Scala, this is a +function of type ``RouteDefinition => ProcessorDefinition[_]``, in Java it is an +instance of ``RouteDefinitionHandler`` which is defined as follows. + +.. code-block:: scala + + package akka.camel + + import org.apache.camel.model.RouteDefinition + import org.apache.camel.model.ProcessorDefinition + + trait RouteDefinitionHandler { + def onRouteDefinition(rd: RouteDefinition): ProcessorDefinition[_] + } + +The akka-camel module creates a RouteDefinition instance by calling +from(endpointUri) on a Camel RouteBuilder (where endpointUri is the endpoint URI +of the consumer actor) and passes that instance as argument to the route +definition handler \*). The route definition handler then extends the route and +returns a ProcessorDefinition (in the above example, the ProcessorDefinition +returned by the end method. See the `org.apache.camel.model`__ package for +details). After executing the route definition handler, akka-camel finally calls +a to(actor:uuid:actorUuid) on the returned ProcessorDefinition to complete the +route to the comsumer actor (where actorUuid is the uuid of the consumer actor). + +\*) Before passing the RouteDefinition instance to the route definition handler, +akka-camel may make some further modifications to it. + +__ https://svn.apache.org/repos/asf/camel/trunk/camel-core/src/main/java/org/apache/camel/model/ + + +Typed actors +^^^^^^^^^^^^ + +For typed consumer actors to define a route definition handler, they must +provide a RouteDefinitionHandler implementation class with the @consume +annotation.

The sample +application transforms the content of the Akka homepage, http://akka.io, by +replacing every occurrence of *Akka* with *AKKA*. After starting +the :ref:`microkernel`, direct the browser to http://localhost:8875 and the +transformed Akka homepage should be displayed. Please note that this example +will probably not work if you're behind an HTTP proxy. + +The following figure gives an overview how the example actors interact with +external systems and with each other. A browser sends a GET request to +http://localhost:8875 which is the published endpoint of the ``HttpConsumer`` +actor. The ``HttpConsumer`` actor forwards the requests to the ``HttpProducer`` +actor which retrieves the Akka homepage from http://akka.io. The retrieved HTML +is then forwarded to the ``HttpTransformer`` actor which replaces all occurences +of *Akka* with *AKKA*. The transformation result is sent back the HttpConsumer +which finally returns it to the browser. + +.. image:: camel-async-interact.png + +Implementing the example actor classes and wiring them together is rather easy +as shown in the following snippet (see also `sample.camel.Boot`_). + +.. code-block:: scala + + import org.apache.camel.Exchange + import akka.actor.Actor._ + import akka.actor.{Actor, ActorRef} + import akka.camel.{Producer, Message, Consumer} + + class HttpConsumer(producer: ActorRef) extends Actor with Consumer { + def endpointUri = "jetty:http://0.0.0.0:8875/" + + protected def receive = { + case msg => producer forward msg + } + } + + class HttpProducer(transformer: ActorRef) extends Actor with Producer { + def endpointUri = "jetty://http://akka.io/?bridgeEndpoint=true" + + override protected def receiveBeforeProduce = { + // only keep Exchange.HTTP_PATH message header (which needed by bridge endpoint) + case msg: Message => msg.setHeaders(msg.headers(Set(Exchange.HTTP_PATH))) + } + + override protected def receiveAfterProduce = { + // do not reply but forward result to transformer + case msg => transformer forward msg + } + } + + class HttpTransformer extends Actor { + protected def receive = { + case msg: Message => self.reply(msg.transformBody {body: String => body replaceAll ("Akka ", "AKKA ")}) + case msg: Failure => self.reply(msg) + } + } + + // Wire and start the example actors + val httpTransformer = actorOf(new HttpTransformer).start + val httpProducer = actorOf(new HttpProducer(httpTransformer)).start + val httpConsumer = actorOf(new HttpConsumer(httpProducer)).start + +The `jetty endpoints`_ of HttpConsumer and HttpProducer support asynchronous +in-out message exchanges and do not allocate threads for the full duration of +the exchange.

Changed the internal structure of cluster meta-data and how it is stored in ZooKeeper. Affected most of the cluster internals which have been rewritten to a large extent. Lots of code removed. 2. Fixed many issues and both known and hidden bugs in the migration code as well as other parts of the cluster functionality. 3. Made the node holding the ClusterActorRef being potentially part of the replica set for the actor it is representing. 4. Changed and cleaned up ClusterNode API, especially the ClusterNode.store methods. 5. Commented out ClusterNode.remove methods until we have a full story how to do removal 6. Renamed Peter's PeterExample test to a more descriptive name 7. Added round robin router test with 3 replicas 8. Rewrote migration tests to actually test correctly 9. Rewrote existing round robin router tests, now more solid 10.

It was possible to get all kinds of strange results like unpredictable merged writes made by concurrent executing threads, unexpected reordering of instructions, and even final fields were not guaranteed to be final. With Java 5 and JSR-133, the Java Memory Model is clearly specified. This specification makes it possible to write code that performs, but doesn't cause concurrency problems. The Java Memory Model is specified in 'happens before'-rules, e.g.: +A major benefit of using the Typesafe Stack, including Scala and Akka, is that it simplifies the process of writing +concurrent software. This article discusses how the Typesafe Stack, and Akka in particular, approaches shared memory +in concurrent applications. -* **monitor lock rule**: a release of a lock happens before every subsequent acquire of the same lock. -* **volatile variable rule**: a write of a volatile variable happens before every subsequent read of the same volatile variable +The Java Memory Model +--------------------- +Prior to Java 5, the Java Memory Model (JMM) was ill defined. It was possible to get all kinds of strange results when +shared memory was accessed by multiple threads, such as: +* a thread not seeing values written by other threads: a visibility problem +* a thread observing 'impossible' behavior of other threads, caused by instructions not being executed in the order + expected: an instruction reordering problem. -The 'happens before'-rules clearly specify which visibility guarantees are provided on memory and which re-orderings are allowed. Without these rules it would not be possible to write concurrent and performant code in Java. +With the implementation of JSR 133 in Java 5, a lot of these issues have been resolved. The JMM is a set of rules based +on the "happens-before" relation, which constrain when one memory access must happen before another, and conversely, +when they are allowed to happen out of order. Two examples of these rules are: +* **The monitor lock rule:** a release of a lock happens before every subsequent acquire of the same lock. +* **The volatile variable rule:** a write of a volatile variable happens before every subsequent read of the same volatile variable +Although the JMM can seem complicated, the specification tries to find a balance between ease of use and the ability to +write performant and scalable concurrent data structures. Actors and the Java Memory Model -------------------------------- +With the Actors implementation in Akka, there are two ways multiple threads can execute actions on shared memory: +* if a message is sent to an actor (e.g. by another actor). In most cases messages are immutable, but if that message + is not a properly constructed immutable object, without a "happens before" rule, it would be possible for the receiver + to see partially initialized data structures and possibly even values out of thin air (longs/doubles). +* if an actor makes changes to its internal state while processing a message, and accesses that state while processing + another message moments later. It is important to realize that with the actor model you don't get any guarantee that + the same thread will be executing the same actor for different messages. -With the Actors implementation in Akka, there are 2 ways multiple threads can execute actions on shared memory over time: - -* if a message is send to an actor (e.g. by another actor). In most cases messages are immutable, but if that message is not a properly constructed immutable object, without happens before rules, the system still could be subject to instruction re-orderings and visibility problems (so a possible source of concurrency errors). -* if an actor makes changes to its internal state in one 'receive' method and access that state while processing another message. With the actors model you don't get any guarantee that the same thread will be executing the same actor for different messages. Without a happens before relation between these actions, there could be another source of concurrency errors. - -To solve the 2 problems above, Akka adds the following 2 'happens before'-rules to the JMM: - -* **the actor send rule**: where the send of the message to an actor happens before the receive of the **same** actor. -* **the actor subsequent processing rule**: where processing of one message happens before processing of the next message by the **same** actor. - +To prevent visibility and reordering problems on actors, Akka guarantees the following two "happens before" rules: +* **The actor send rule:** the send of the message to an actor happens before the receive of that message by the same actor. +* **The actor subsequent processing rule:** processing of one message happens before processing of the next message by the same actor. Both rules only apply for the same actor instance and are not valid if different actors are used. STM and the Java Memory Model ----------------------------- +Akka's Software Transactional Memory (STM) also provides a "happens before" rule: -The Akka STM also provides a happens before rule called: - -* **the transaction rule**: a commit on a transaction happens before every subsequent start of a transaction where there is at least 1 shared reference. - -How these rules are realized in Akka, is an implementation detail and can change over time (the exact details could even depend on the used configuration) but they will lift on the other JMM rules like the monitor lock rule or the volatile variable rule. Essentially this means that you, the Akka user, do not need to worry about adding synchronization to provide such a happens before relation, because it is the responsibility of Akka. So you have your hands free to deal with your problems and not that of the framework. - +* **The transactional reference rule:** a successful write during commit, on an transactional reference, happens before every + subsequent read of the same transactional reference. +This rule looks a lot like the 'volatile variable' rule from the JMM. Currently the Akka STM only supports deferred writes, +so the actual writing to shared memory is deferred until the transaction commits. Writes during the transaction are placed +in a local buffer (the writeset of the transaction) and are not visible to other transactions. That is why dirty reads are +not possible. +How these rules are realized in Akka is an implementation detail and can change over time, and the exact details could +even depend on the used configuration. But they will build on the other JMM rules like the monitor lock rule or the +volatile variable rule. This means that you, the Akka user, do not need to worry about adding synchronization to provide +such a "happens before" relation, because it is the responsibility of Akka. So you have your hands free to deal with your +business logic, and the Akka framework makes sure that those rules are guaranteed on your behalf. \ No newline at end of file From
