For a fully detailed documentation, please +see [https://statefun.io](https://statefun.io). + +## Table of Contents + +- [Core Concepts](#core-concepts) + * [Abstraction](#abstraction) + * [Function modules and extensibility](#modules) +- [Getting Started](#getting-started) + * [Building the project](#build) + * [Running a full example](#greeter) + * [Project setup](#project-setup) + * [Running in the IDE](#ide-harness) +- [Deploying Applications](#deploying) + * [Deploying with a Docker image](#docker) + * [Deploying as a Flink job](#flink) +- [Contributing](#contributing) +- [License](#license) + +## Core Concepts + +### Abstraction + +A Stateful Functions application consists of the following primitives: stateful functions, ingresses, +routers, and egresses. + +#### Stateful functions + +* Stateful functions are the building blocks and namesake of the Stateful Functions framework. +A function is a small piece of logic (currently simple Java functions) that are invoked through a message. + +* Each stateful function exist as uniquely invokable _virtual instances_ of a _function type_. Each instance +is addressed by its type, as well as an unique id (a string) within its type. + +* Stateful functions may be invoked from ingresses or any other stateful function (including itself). +The caller simply needs to know the address of the target function. + +* Function instances are _virtual_, because they are not all active in memory at the same time. +At any point in time, only a small set of functions and their state exists as actual objects. When a +virtual instance receives a message, one of the objects is configured and loaded with the state of that virtual +instance and then processes the message. Similar to virtual memory, the state of many functions might be “swapped out” +at any point in time. + +* Each virtual instance of a function has its own state, which can be accessed in local variables. +That state is private and local to that instance. + +If you know Apache Flink’s DataStream API, you can think of stateful functions a bit like a lightweight +`KeyedProcessFunction`. The function type is process function transformation, while the ID is the key. The difference +is that functions are not assembled in a directed acyclic graph that defines the flow of data (the streaming topology), +but rather send events arbitrarily to all other functions using addresses. + +#### Ingresses and Egresses + +* _Ingresses_ are the way that events initially arrive in a Stateful Functions application. +Ingresses can be message queues, logs, or HTTP servers - anything that produces an event to be +handled by the application. + +* _Routers_ are attached to ingresses to determine which function instance should handle an event initially. + +* _Egresses_ are a way to send events out from the application in a standardized way. +Egresses are optional; it is also possible that no events leave the application and functions sink events or +directly make calls to other applications. + +### Modules and extensibility + +A _module_ is the entry point for adding to a Stateful Functions +application the core building block primitives, i.e. ingresses, egresses, routers, and stateful functions. + +A single application may be a combination of multiple modules, each contributing a part of the whole application. +This allows different parts of the application to be contributed by different modules; for example, +one module may provide ingresses and egresses, while other modules may individually contribute specific parts of the +business logic as stateful functions. This facilitates working in independent teams, but still deploying +into the same larger application. + +This extensibility is achieved by leveraging the [Java Service Loader](https://docs.oracle.com/javase/tutorial/ext/basics/spi.html#the-serviceloader-class). +In this context, each module is essentially a service provider. + +## Getting Started + +Follow the steps here to get started right away with Stateful Functions. + +This guide will walk you through locally building the project, running an existing example, and setup to +start developing and testing your own Stateful Functions application. + +### Building the project + +Prerequisites: + +* Docker +* Maven 3.5.x or above +* Java 8 or above + +Currently, the project does not have any publicly available artifacts or Docker images for use, so you would have to +first build the project yourself before trying it out. + +``` +mvn clean install +``` + +If you want to [deploy your applications using Docker](#docker), you should also build the base Docker image: + +``` +./tools/docker/build-stateful-functions.sh +``` + +### Running a full example + +As a simple demonstration, we will be going through the steps to run the [Greeter example](stateful-functions-examples/stateful-functions-greeter-example). + +Before anything else, make sure that you have locally [built the project as well as the base Stateful Functions Docker image](#build). +Then, follow the next steps to run the example: + +``` +cd stateful-functions-examples/stateful-functions-greeter-example +docker-compose build +docker-compose up +``` + +This example contains a very basic stateful function with a Kafka ingress and a Kafka egress. + +To see the example in action, send some messages to the topic `names`, and see what comes out out of the topic `greetings`: + +``` +KAFKA=$(docker ps -f "name=stateful-functions-greeter-example_kafka-broker_1" --format "{{.ID}}") ; \ +docker exec -it $KAFKA kafka-console-producer.sh \ + --broker-list localhost:9092 \ + --topic names +``` + +``` +KAFKA=$(docker ps -f "name=stateful-functions-greeter-example_kafka-broker_1" --format "{{.ID}}") ; \ +docker exec -it $KAFKA kafka-console-consumer.sh \ + --bootstrap-server localhost:9092 \ + --topic greetings +``` + +### Project setup + +You can quickly get started building Stateful Functions applications using the provided quickstart Maven archetype: + +``` +mvn archetype:generate \ + -DarchetypeGroupId=com.ververica \ + -DarchetypeArtifactId=stateful-functions-quickstart \ + -DarchetypeVersion=1.0-SNAPSHOT +``` + +This allows you to name your newly created project. It will interactively ask you for the groupId, +artifactId, and package name. There will be a new directory with the same name as your artifact id. + +We recommend you import this project into your IDE to develop and test it. +IntelliJ IDEA supports Maven projects out of the box. If you use Eclipse, the `m2e` plugin allows to import +Maven projects. Some Eclipse bundles include that plugin by default, others require you to install it manually. + +### Running from the IDE + +To test out your application, you can directly run it in the IDE without any further packaging or deployments. + +Please see the [Harness example](stateful-functions-examples/stateful-functions-flink-harness-example) on how to do that. + +## Deploying Applications + +Stateful Functions applications can be packaged as either standalone applications or Flink jobs that can be +submitted to a Flink cluster. + +### Deploying with a Docker image + +Below is an example Dockerfile for building an image for an application called `stateful-functions-example`: + +``` +FROM stateful-functions + +RUN mkdir -p /opt/stateful-functions/modules/stateful-functions-example +COPY target/stateful-functions-example*jar /opt/stateful-functions/modules/stateful-functions-example/ +``` + +### Deploying as a Flink job + +If you prefer to package your Stateful Functions application as a Flink job to submit to an existing Flink cluster, +simply include `stateful-functions-flink-distribution` as a dependency to your application. + +``` + + com.ververica + stateful-functions-flink-distribution + 1.0-SNAPSHOT + +``` + +It includes all the runtime dependencies and configures the application's main entry-point. +You do not need to take any action beyond adding the dependency to your Maven pom. + +Bundle the distribution with your application as a fat jar, and then submit it as you normally would +with any other Flink job: + +``` +{$FLINK_DIR}/bin/flink run ./stateful-functions-example.jar +``` + +## Contributing + +If you find these ideas interesting or promising, try Stateful Functions out and get involved! +Check out the example walkthrough or the docs. File an issue if you have an idea how to improve things. + +The project is work-in-progress. We believe we are off to a promising direction, but there is still a +way to go to make all parts of this vision a reality. There are many possible ways to enhance the Stateful +Functions API for different types of applications. Runtime and operations of Stateful Functions +will also evolve with the capabilities of Apache Flink. + +## License + +The code in this repository is under the Apache license.

The following is an example of a simple hello world function. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/FnHelloWorld.java + :language: java + :lines: 16- + +Functions process each incoming message through their ``invoke`` method. +Input's are untyped and passed through the system as a ``java.lang.Object`` so one function can potentially process multiple types of messages. + +The ``Context`` provides metadata about the current message and function, and is how you can call other functions or external systems. +Functions are invoked based on a function type and unique identifier. + +Function Type's and Identifiers +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +In a local environment, the address of an object is the same as a reference to it. +But in a distributed system, objects may be spread across multiple machines and may or may not be active at any given moment. + +In Stateful Functions, function types and identifiers are used to reference specific stateful functions in the system. +A function type is similar to a class in an object-oriented language; it declares what sort of function the address references. +The id is a primary key and scopes the function call to a specific instance of the function type. + +Suppose a Stateful Functions application was tracking metadata about each user account on a website. +The system would contain a user stateful function that accepts and responds to inputs about users and tracks relevant information. +Stateful Functions will create one virtual instance of this stateful function for every user. +Other functions can call the function for any particular user by the user function type and using the current user id as the instance identifier. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/FnUser.java + :language: java + :emphasize-lines: 10 + :lines: 16- + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/FnCaller.java + :language: java + :emphasize-lines: 14 + :lines: 16- + +Virtual Functions +^^^^^^^^^^^^^^^^^ + +Functions are virtual, which means the system can support an infinite number of active functions while only requiring a static number of physical objects on the JVM heap. +Any function can call any other without ever triggering an allocation. +The system will make it appear as if functions are always available in-memory. + +Stateful Functions applications deploy on Apache Flink's horizontally parallel runtime. +If the user function, seen above, is run on a Flink cluster with a parallelism of 10, then only ten objects will ever be allocated. +Even if the application creates a billion user functions for a billion different users, memory usage will be stable. +Those billion virtual functions will be evenly partitioned and run by the ten underlying objects. +New object creation only occurs the first time a function of that type, regardless of id, is needed. + +Sending Delayed Messages +^^^^^^^^^^^^^^^^^^^^^^^^ + +Functions are able to send messages on a delay so that they will arrive after some duration. +Functions may even send themselves delayed messages that can serve as a callback. +The delayed message is non-blocking so functions will continue to process records between the time a delayed message is sent and received. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/delay/FnDelayedMessage.java + :language: java + :lines: 16- + +Completing Async Requests +^^^^^^^^^^^^^^^^^^^^^^^^^ + +When interacting with external systems, such as a database or API, one needs to take care that communication delay with the external system does not dominate the application’s total work. +Stateful Functions allows registering a java ``CompletableFuture`` that will resolve to a value at some point in the future. +Future's are registered along with a metadata object that provides additional context about the caller. + +When the future completes, either successfully or exceptionally, the caller function type and id will be invoked with a ``AsyncOperationResult``. +An asynchronous result can complete in one of three states: + +Success +======= + +The asynchronous operation has succeeded, and the produced result can be obtained via ``AsyncOperationResult#value``. + +Failure +======= + +The asynchronous operation has failed, and the cause can be obtained via ``AsyncOperationResult#throwable``. + +Unknown +======= + +The stateful function was restarted, possibly on a different machine, before the ``CompletableFuture`` was completed, therefore it is unknown what is the status of the asynchronous operation. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/async/EnrichmentFunction.java + :language: java + :lines: 16- + +Function Providers and Dependency Injection +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Stateful functions are created across a distributed cluster of nodes. +``StatefulFunctionProvider`` is a factory class for creating a new instance of a stateful function the first time it is activated. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/CustomProvider.java + :language: java + :lines: 16- + +Providers are called once per type on each parallel worker, not for each id. +If a stateful function requires custom configurations, they can be defined inside a provider and passed to the functions' constructor. +This is also where shared physical resources, such as a database connection, can be created that are used by any number of virtual functions. +Now, tests can quickly provide mock, or test dependencies, without the need for complex dependency injection frameworks. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/FunctionTest.java + :language: java + :lines: 16- + +.. _module: + +Stateful Function Modules +^^^^^^^^^^^^^^^^^^^^^^^^^ + +Modules define a Stateful Functions application's top-level entry point and are where everything gets tied together. +They offer a single configuration method where stateful functions are bound to the system. +It also provides runtime configurations through the ``globalConfguration`` which is the union of all configurations in the applications ``flink-conf.yaml`` and any command line arguments passed in the form ``--key value``. + +.. literalinclude:: ../../src/main/java/com/ververica/statefun/docs/BasicFunctionModule.java +

These functions exist as virtual instances — typically, one per entity in the application (for example, per user or stock item) — and are distributed across shards, making applications **scalable out-of-the-box**. Each function has persistent user-defined state in local variables and can message other functions (including itself!). This model makes **computing with state natural and uncomplicated**. + +.. topic:: Stream Processing Runtime + + The runtime that powers **Stateful Functions** is based on stream processing with Apache Flink. State is kept in the stream processing engine, co-located with the computation, giving you fast and consistent state access. **State durability and fault tolerance** build on Flink’s robust `distributed snapshots model `_. + +.. topic:: Messaging Model + + In **Stateful Functions** applications, everything is inherently strongly consistent: state modifications and messaging are integrated to create the effect of **consistent state and reliable messaging** within all interacting functions. Care about consistency needs to be taken only when interacting with the "outside world”. Event Ingresses and Egresses — optionally with transactional semantics — support interaction with the “outside world” via event streams. + +.. topic:: Consistency Model + + Interactions flow between functions as event streams, in the style of message passing. Apache Flink’s snapshot-based fault tolerance model was extended to support cyclic data flow graphs while ensuring **exactly-once messaging guarantees** (yay!). As a result, you can have functions messaging each other arbitrarily, efficiently, and reliably. + +**Stateful Functions** splits compute and storage differently to the classical two-tier architecture: one ephemeral state/compute tier and a simple persistent blob storage tier. This approach **eliminates the need to provision additional databases, key-value stores or message brokers** and effectively offloads application state management from the shoulders of developers. + +Technology Space +################ + +Stateful Functions is heavily inspired by multiple existing technologies for stateless application development and orchestration. Other than Apache Flink, also Function-as-a-Service (FaaS) systems such as AWS Lambda and the `virtual stateful actor model `_ from Microsoft Orleans served as inspiration for this project. + +The framework is mostly implemented in Java and runs on the JVM. Extending the API to be cross-language compatible and support languages like Python, Go or NodeJS is part of the :ref:`Roadmap `. + +Get Involved! +############# + +If you find these ideas interesting, give **Stateful Functions** a try and get involved! Check out the Getting Started section for introduction walkthroughs. File an issue if you have an idea how to improve things. + +The project is a work-in-progress. We believe we are off to a promising direction, but there is still a way to go to make all parts of this vision a reality. There are many possible ways to enhance **Stateful Functions** for different types of applications. Possibilities for enhancements to the runtime and operations will also evolve with the evolution of capabilities of Apache Flink. \ No newline at end of file diff --git a/stateful-functions-docs/docs/overview/stateful_functions.rst b/stateful-functions-docs/docs/overview/stateful_functions.rst new file mode 100644 index 00000000..d654ff2e --- /dev/null +++ b/stateful-functions-docs/docs/overview/stateful_functions.rst @@ -0,0 +1,19 @@ +..

Concept

+ * + *

Each individual {@code StatefulFunction} is an uniquely invokable "instance" of a {@link + * FunctionType}. Each function is identified by an {@link Address}, representing the function's + * unique id (a string) within its type. From a user's perspective, it would seem as if for each + * unique function id, there exists a stateful instance of the function that is always available to + * be invoked within a Stateful Functions application. + * + *

Invoking a {@code StatefulFunction}

+ * + *

An individual {@code StatefulFunction} can be invoked with arbitrary input from any another + * {@code StatefulFunction} (including itself), or routed from ingresses via a {@link Router}. To + * invoke a {@code StatefulFunction}, the caller simply needs to know the {@code Address} of the + * target function. + * + *

As a result of invoking a {@code StatefulFunction}, the function may continue to invoke other + * functions, modify its state, or send messages to egresses addressed by an {@link + * EgressIdentifier}. + * + *

State

+ * + *

Each individual {@code StatefulFunction} may have state that is maintained by the system, + * providing exactly-once guarantees. Below is a code example of how to register and access state in + * functions: + * + * 

{@code
+ * public class MyFunction implements StatefulFunction {
+ *
+ *     @Persisted
+ *     PersistedValue intState = PersistedValue.of("state-name", Integer.class);
+ *
+ *     @Override
+ *     public void invoke(Context context, Object input) {
+ *         Integer stateValue = intState.get();
+ *         //...
+ *         intState.set(1108);
+ *         // send messages using context
+ *     }
+ * }
+ * }
+ * + * @see Address + * @see FunctionType + * @see Persisted + * @see PersistedValue + */ +public interface StatefulFunction { + + /** + * Invokes this function with a given input. + * + * @param context context for the current invocation.

Extensibility of a Stateful Functions application

+ * + *

A Stateful Functions application is built up of ingresses, egresses, routers, and stateful + * functions that are added to the application by multiple different {@link + * StatefulFunctionModule}s. This allows different parts of the application to be contributed by + * different modules; for example, one module may provide ingresses and egresses, while other + * modules may individually contribute specific parts of the application as stateful functions. + * + *

The extensibility is achieved by leveraging the Java + * Service Loader. In this context, each module is essentially a service provider. + * + *

Registering a {@code StatefulFunctionModule}

+ * + *

In order for an application to discover a given module, likewise to how the Java Service + * Loader works, a UTF-8 encoded provider configuration file needs to be stored in the {@code + * MEGA-INF/services} directory of the module's containing JAR file. The name of the file should be + * {@code com.ververica.statefun.sdk.spi.StatefulFunctionModule}, i.e. the fully qualified name of + * the {@link StatefulFunctionModule} class. Each line in the file should be the fully qualified + * class name of a module in that JAR that you want to register for the Stateful Functions + * application. + * + *

Finally, to allow the Stateful Functions runtime to discover the registered modules, the JAR + * files containing the modules and provider configuration files should be added to a + * system-specific class path directory, {@code /opt/stateful-functions/modules/}. + * + *

For a simple demonstration, you can consult the {@code stateful-functions-greeter-example} + * example. + */ +public interface StatefulFunctionModule { + + /** + * This method is the entry point for extending a Stateful Functions application by binding + * ingresses, egresses, routers, and functions. + * + * @param globalConfiguration global configuration of the Stateful Functions application. + * @param binder the binder to be used to bind ingresses, egresses, routers, and functions. + */ + void configure(Map globalConfiguration, Binder binder); + + /** + * A {@link Binder} binds ingresses, egresses, routers, and functions to a Stateful Functions + * application. + */ + interface Binder { + + /** + * Binds an {@link IngressSpec} to the Stateful Functions application. + * + * @param spec the {@link IngressSpec} to bind. + * @param the output type of the ingress. + */ + void bindIngress(IngressSpec spec); + + /** + * Binds an {@link EgressSpec} to the Stateful Functions application. + * + * @param spec the {@link EgressSpec} to bind. + * @param the type of inputs that the egress consumes. + */ + void bindEgress(EgressSpec spec); + + /** + * Binds a {@link StatefulFunctionProvider} to the Stateful Functions application. + * + * @param functionType the type of functions that the {@link StatefulFunctionProvider} provides. + * @param provider the provider to bind. + */ + void bindFunctionProvider(FunctionType functionType, StatefulFunctionProvider provider); + + /** + * Binds a {@link Router} for a given ingress to the Stateful Functions application. + * + * @param id the id of the ingress to bind the router to. + * @param router the router to bind. + * @param the type of messages that is bbeing routed. + */ + void bindIngressRouter(IngressIdentifier id, Router router); + } +} diff --git a/stateful-functions-sdk/src/main/java/com/ververica/statefun/sdk/state/Accessor.java b/stateful-functions-sdk/src/main/java/com/ververica/statefun/sdk/state/Accessor.java new file mode 100644 index 00000000..0b7148e1 --- /dev/null +++ b/stateful-functions-sdk/src/main/java/com/ververica/statefun/sdk/state/Accessor.java @@ -0,0 +1,26 @@ +/* + * Copyright 2019 Ververica GmbH. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +package com.ververica.statefun.sdk.state; + +public interface Accessor { + + void set(T value); + + T get(); + + void clear(); +} diff --git a/stateful-functions-sdk/src/main/java/com/ververica/statefun/sdk/state/PersistedValue.java b/stateful-functions-sdk/src/main/java/com/ververica/statefun/sdk/state/PersistedValue.java new file mode 100644 index 00000000..f1d670b2 --- /dev/null +++ b/stateful-functions-sdk/src/main/java/com/ververica/statefun/sdk/state/PersistedValue.java @@ -0,0 +1,164 @@ +/* + * Copyright 2019 Ververica GmbH. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +package com.ververica.statefun.sdk.state; + +import com.ververica.statefun.sdk.StatefulFunction; +import com.ververica.statefun.sdk.annotations.ForRuntime; +import com.ververica.statefun.sdk.annotations.Persisted; +import java.util.Objects; +import java.util.function.Function; +import java.util.function.Supplier; + +/** + * A {@link PersistedValue} is a value registered within {@link StatefulFunction}s and is persisted + * and maintained by the system for fault-tolerance. + * + *
