The Job builder lets you create a job pipeline programmatically using Talend components (Producers and Processors). The job pipeline is an acyclic graph, allowing you to build complex pipelines.
Let’s take a simple use case where two data sources (employee and salary) are formatted to CSV and the result is written to a file.
A job is defined based on components (nodes) and links (edges) to connect their branches together.
Every component is defined by a unique id and an URI that identify the component.
The URI follows the form [family]://[component][?version][&configuration], where:
family is the name of the component family.
component is the name of the component.
version is the version of the component. It is represented in a key=value format. The key is __version and the value is a number.
configuration is component configuration. It is represented in a key=value format. The key is the path of the configuration and the value is a `string' corresponding to the configuration value.
URI example:
configuration parameters must be URI/URL encoded.
Job example:
It has some starting components (components that don’t have a from connection and that need to be of the producer type).
There are no cyclic connections. The job pipeline needs to be an acyclic graph.
All components used in the connections are already declared.
Each connection is used only once. You cannot connect a component input/output branch twice.
In this version, the execution of the job is linear. Components are not executed in parallel even if some steps may be independents.
Depending on the configuration, you can select the environment which you execute your job in.
To select the environment, the logic is the following one:
If an org.talend.sdk.component.runtime.manager.chain.Job.ExecutorBuilder class is passed through the job properties, then use it. The supported types are an ExecutionBuilder instance, a Class or a String.
If an ExecutionBuilder SPI is present, use it. It is the case if component-runtime-beam is present in your classpath.
Else, use a local/standalone execution.
In the case of a Beam execution, you can customize the pipeline options using system properties. They have to be prefixed with talend.beam.job.. For example, to set the appName option, you need to use -Dtalend.beam.job.appName=mytest.
The job builder lets you set a key provider to join your data when a component has multiple inputs. The key provider can be set contextually to a component or globally to the job.
If the incoming data has different IDs, you can provide a complex global key provider that relies on the context given by the component id and the branch name.
For Beam case, you need to rely on Beam pipeline definition and use the component-runtime-beam dependency, which provides Beam bridges.
org.talend.sdk.component.runtime.beam.TalendIO provides a way to convert a partition mapper or a processor to an input or processor using the read or write methods.
org.talend.sdk.component.runtime.beam.TalendFn provides the way to wrap a processor in a Beam PTransform and to integrate it into the pipeline.
The multiple inputs and outputs are represented by a Map element in Beam case to avoid using multiple inputs and outputs.
You can use ViewsMappingTransform or CoGroupByKeyResultMappingTransform to adapt the input/output format to the record format representing the multiple inputs/output, like Map

component-runtime-junit is a test library that allows you to validate simple logic based on the Talend Component Kit tooling.
To import it, add the following dependency to your project:
This dependency also provides mocked components that you can use with your own component to create tests.
The mocked components are provided under the test family:
emitter : a mock of an input component
collector : a mock of an output component
The collector is "per thread" by default. If you are executing a Beam (or concurrent) job, it will not work. To switch to a JVM wide storage, set the talend.component.junit.handler.state system property to static (default being thread). You can do it in a maven-surefire-plugin execution.
You can define a standard JUnit test and use the SimpleComponentRule rule:
The rule can also be defined as a @ClassRule to start it once per class and not per test as with @Rule.
To go further, you can add the ServiceInjectionRule rule, which allows to inject all the component family services into the test class by marking test class fields with @Service:
The JUnit 5 integration is very similar to JUnit 4, except that it uses the JUnit 5 extension mechanism.
The entry point is the @WithComponents annotation that you add to your test class, and which takes the component package you want to test. You can use @Injected to inject an instance of ComponentsHandler - which exposes the same utilities than the JUnit 4 rule - in a test class field :
If you use JUnit 5 for the first time, keep in mind that the imports changed and that you need to use org.junit.jupiter.api.Test instead of org.junit.Test. Some IDE versions and surefire versions can also require you to install either a plugin or a specific configuration.
As for JUnit 4, you can go further by injecting test class fields marked with @Service, but there is no additional extension to specify in this case:
Streaming components have the issue to not stop by design. The Job dsl exposes two properties to help with that issue:
streaming.maxRecords: enables to request a maximum number of records
streaming.maxDurationMs: enables to request a maximum duration for the execution of the input
You can set them as properties on the job:
Using the test://collector component as shown in the previous sample stores all records emitted by the chain (typically your source) in memory. You can then access them using theSimpleComponentRule.getCollectedData(type).
Note that this method filters by type. If you don’t need any specific type, you can use Object.class.
The input mocking is symmetric to the output. In this case, you provide the data you want to inject:
The component configuration is a POJO (using @Option on fields) and the runtime configuration (ExecutionChainBuilder) uses a Map
The entry point of the API is the ContainerManager. It allows you to define what is the Shared classloader and to create children: how to resolve dependencies for plugins from the plugin file/location how to configure the classloaders (what is the parent classloader, how to handle the parent first/last delegation, and so on). It is recommended to keep the manager running if you can reuse plugins in order to avoid recreating classloaders and to mutualize them. What the shared classloader is Which classes are loaded from the shared loader first (intended to be used for API which should not be loaded from the plugin loader) Which classes are loaded from the parent classloader. This can be useful to prevent loading a "common" library from the parent classloader. For instance, it can be neat for guava, commons-lang3, an so on). Once you have defined a manager, you can create plugins: To create the plugin container, the Resolver resolves the dependencies needed for the plugin, then the manager creates the plugin classloader and registers the plugin Container. Some actions are needed when a plugin is registered or unregistered. For that purpose, you can use ContainerListener: Plugins are directly registered on the manager:
JUnit (4 or 5) already provides ways to parameterize tests and execute the same "test logic" against several sets of data. However, it is not very convenient for testing multiple environments.
For example, with Beam, you can test your code against multiple runners. But it requires resolving conflicts between runner dependencies, setting the correct classloaders, and so on.
To simplify such cases, the framework provides you a multi-environment support for your tests, through the JUnit module, which works with both JUnit 4 and JUnit 5.
The MultiEnvironmentsRunner executes the tests for each defined environments. With the example above, it means that it runs test1 for Env1 and Env2.
By default, the JUnit4 runner is used to execute the tests in one environment, but you can use @DelegateRunWith to use another runner.
The multi-environment configuration with JUnit 5 is similar to JUnit 4:
The main differences are that no runner is used because they do not exist in JUnit 5, and that you need to replace @Test by @EnvironmentalTest.
With JUnit5, tests are executed one after another for all environments, while tests are ran sequentially in each environments with JUnit 4. For example, this means that @BeforeAll and @AfterAll are executed once for all runners.
The provided environment sets the contextual classloader in order to load the related runner of Apache Beam.
Package: org.talend.sdk.component.junit.environment.builtin.beam
the configuration is read from system properties, environment variables, ….
_class: ContextualEnvironment.
_class: DirectRunnerEnvironment.
_class: FlinkRunnerEnvironment.
_class: SparkRunnerEnvironment.
If the environment extends BaseEnvironmentProvider and therefore defines an environment name - which is the case of the default ones - you can use EnvironmentConfiguration to customize the system properties used for that environment:
If you set the
Talend Component scanning is based on plugins. To make sure that plugins can be developed in parallel and avoid conflicts, they need to be isolated (component or group of components in a single jar/plugin).
Multiple options are available:
Graph classloading: this option allows you to link the plugins and dependencies together dynamically in any direction. For example, the graph classloading can be illustrated by OSGi containers.
Tree classloading: a shared classloader inherited by plugin classloaders. However, plugin classloader classes are not seen by the shared classloader, nor by other plugins. For example, the tree classloading is commonly used by Servlet containers where plugins are web applications.
Flat classpath: listed for completeness but rejected by design because it doesn’t comply with this requirement.
In order to avoid much complexity added by this layer, Talend Component Kit relies on a tree classloading. The advantage is that you don’t need to define the relationship with other plugins/dependencies, because it is built-in.
Here is a representation of this solution:
The shared area contains Talend Component Kit API, which only contains by default the classes shared by the plugins.
Then, each plugin is loaded with its own classloader and dependencies.
This section explains the overall way to handle dependencies but the Talend Maven plugin provides a shortcut for that.
A plugin is a JAR file that was enriched with the list of its dependencies. By default, Talend Component Kit runtime is able to read the output of maven-dependency-plugin in TALEND-INF/dependencies.txt. You just need to make sure that your component defines the following plugin:
Once build, check the JAR file and look for the following lines:
What is important to see is the scope related to the artifacts:
The APIs (component-api and geronimo-annotation_1.3_spec) are provided because you can consider them to be there when executing (they come with the framework).
Your specific dependencies (awesome-project in the example above) are marked as compile: they are included as needed dependencies by the framework (note that using runtime works too).
the other dependencies are ignored. For example, test dependencies.
Even if a flat classpath deployment is possible, it is not recommended because it would then reduce the capabilities of the components.
The way the framework resolves dependencies is based on a local Maven repository layout. As a quick reminder, it looks like:
This is all the layout the framework uses. The logic converts t-uple {groupId, artifactId, version, type (jar)} to the path in the repository.
Talend Component Kit runtime has two ways to find an artifact:
From the file system based on a configured Maven 2 repository.
From a fat JAR (uber JAR) with a nested Maven repository under MAVEN-INF/repository.
The first option uses either ${user.home}/.m2/repository (default) or a specific path configured when creating a ComponentManager. The nested repository option needs some configuration during the packaging to ensure the repository is correctly created.
To create the nested MAVEN-INF/repository repository, you can use the nested-maven-repository extension:
Plugins are usually programmatically registered. If you want to make some of them automatically available, you need to generate a TALEND-INF/plugins.properties file that maps a plugin name to coordinates found with the Maven mechanism described above.
You can enrich maven-shade-plugin to do it:
Here is a final job/application bundle based on maven-shade-plugin:
The configuration unrelated to transformers depends on your application.
ContainerDependenciesTransformer embeds a Maven repository and PluginTransformer to create a file that lists (one per line) artifacts (representing plugins).
Both transformers share most of their configuration:
session: must be set to ${session}. This is used to retrieve dependencies.
scope: a comma-separated list of scopes to include in the artifact filtering (note that the default will rely on provided but you can replace it by compile, runtime, runtime+compile, runtime+system or test).
include: a comma-separated list of artifacts to include in the artifact filtering.
exclude: a comma-separated list of artifacts to exclude in the artifact filtering.
userArtifacts: set of artifacts to include (groupId, artifactId, version, type - optional, file - optional for plugin transformer, scope - optional) which can be forced inline. This parameter is mainly useful for PluginTransformer.
includeTransitiveDependencies: should transitive dependencies of the components be included. Set to true by default. It is active for userArtifacts.
includeProjectComponentDependencies: should component project dependencies be included. Set to false by default. It is not needed when a job project uses isolation for components.
With the component tooling, it is recommended to keep default locations. Also if you need to use project dependencies, you can need to refactor your project structure to ensure component isolation. Talend Component Kit lets you handle that part but the recommended practice is to use userArtifacts for the components instead of project
The component configuration is defined in the

You can also find sample working components for each of the configuration cases below: ActiveIf: Add visibility conditions on some configurations. Checkbox: Add checkboxes or toggles to your component. Code: Allow users to enter their own code. Credential: Mark a configuration as sensitive data to avoid displaying it as plain text. Datastore: Add a button allowing to check the connection to a datastore. Datalist: Two ways of implementing a dropdown list with predefined choices. Integer: Add numeric fields to your component configuration. Min/Max: Specify a minimum or a maximum value for a numeric configuration. Multiselect: Add a list and allow users to select multiple elements of that list. Pattern: Enforce rules based on a specific a pattern to prevent users from entering invalid values. Required: Make a configuration mandatory. Suggestions: Suggest possible values in a field based on what the users are entering. Table: Add a table to your component configuration. Textarea: Add a text area for configurations expecting long texts or values. Input: Add a simple text input field to the component configuration Update: Provide a button allowing to fill a part of the component configuration based on a service.

Integrate components you developed using Talend Component Kit to Talend Studio in a few steps. Also learn how to enable the developer and debugging modes to iterate on your component development. The version of Talend Component Kit you need to use to develop new components depends on the version of Talend Studio in which components will be integrated. Refer to this document to learn about compatibility between Talend Component Kit and the different versions of Talend applications. Learn how to build and deploy components to Talend Studio using Maven or Gradle Talend Component Kit plugins. This can be done using the deploy-in-studio goal from your development environment. If you are unfamiliar with component development, you can also follow this example to go through the entire process, from creating a project to using your new component in Talend Studio. The Studio integration relies on the Component Server, that the Studio uses to gather data about components created using Talend Component Kit. You can change the default configuration of component server by modifying the $STUDIO_HOME/configuration/config.ini file. The following parameters are available: Name Description Default component.environment Enables the developer mode when set to dev - component.debounce.timeout Specifies the timeout (in milliseconds) before calling listeners in components Text fields 750 component.kit.skip If set to true, the plugin is not enabled. It is useful if you don’t have any component developed with the framework. false component.java.arguments Component server additional options - component.java.m2 Maven repository that the server uses to resolve components Defaults to the global Studio configuration component.java.coordinates A list of comma-separated GAV (groupId:artifactId:version) of components to register - component.java.registry A properties file with values matching component GAV (groupId:artifactId:version) registered at startup. Only use slashes (even on windows) in the path. - component.java.port Sets the port to use for the server random component.server.extensions A comma separated list of gav to locate the extensions. - components.server.beam.active Active, if set to true, Beam support (Experimental). It requires Beam SDK Java core dependencies to be available. false component.server.jul.forceConsole Adds a console handler to JUL to see logs in the console. This can be helpful in development because the formatting is clearer than the OSGi one in workspace/.metadata/.log. It uses the java.util.logging.SimpleFormatter.format property to define its format. By default, it is %1$tb %1$td, %1$tY %1$tl:%1$tM:%1$tS %1$Tp %2$s%n%4$s: %5$s%6$s%n, but for development purposes [%4$s] %5$s%6$s%n is simpler and more readable. false Here is an example of a common developer configuration/config.ini file: The developer mode is especially useful to iterate on your component development and to avoid closing and restarting Talend Studio every time you make a change to a component. It adds a Talend Component Kit button in the main toolbar: When clicking this button, all components developed with the Talend Component Kit framework are reloaded. The cache is invalidated and the components refreshed. You still need to add and remove the components to see the changes. To enable it, simply set the component.environment parameter to dev in the config.ini configuration file of the component server. Several methods allow you to debug custom components created with Talend Component Kit in Talend Studio. From your development tool, create a new Remote configuration, and copy the Command line arguments for running remote JVM field. For example, -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005, where: the suspend parameter of the -agentlib argument specifies whether you want to suspend the debugged JVM until the debugger attaches to it. Possible values are n (no, default value) or y (yes). the address parameter of the -agentlib argument is the port used for the remote configuration. Make sure this port is available. Open Talend Studio. Create a new Job that uses the component you want to debug or open an existing one that already uses it. Go to the Run tab of the Job and select Use specific JVM arguments. Click New to add an argument. In the popup window, paste the arguments copied from the IDE. Enter the corresponding debug mode: To debug the runtime, run the Job and access the remote host configured in the IDE. To debug the Guess schema option, click the Guess schema action button of the component and access the remote host configured in the IDE. From your development tool, create a new Remote configuration, and copy the Command line arguments for running remote JVM field. For example, -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005, where: suspend defines whether you need to access the defined configuration to run the remote JVM. Possible values are n (no, default value) or y (yes). address is the port used for the remote configuration. Make sure this port is available. Access the installation directory of your Talend Sutdio. Open the .ini file corresponding to your Operating System. For example, TOS_DI-win-x86_64.ini. Paste the arguments copied from the IDE in a new line of the file. Go to Talend Studio to use the component, and access the host host configured in the IDE. If you run multiple Studio instances automatically in parallel, you can run into some issues with the random port computation. For example on a CI platform. For that purpose, you can create the $HOME/.talend/locks/org.talend.sdk.component.studio-integration.lock file. Then, when a server starts, it acquires a lock on that file and prevents another server to get a port until it is started. It ensures that you can’t have two concurrent processes getting the same port allocated. However, it is highly unlikely to happen on a desktop. In that case, forcing a different value through component.java.port in your config.ini file is a better solution for local installations.
The framework provides built-in services that you can inject by type in components and actions.
Type
Description

org.talend.sdk.component.api.service.configuration.LocalConfiguration
Represents the local configuration that can be used during the design.
It is not recommended to use it for the runtime because the local configuration is usually different and the instances are distinct.
You can also use the local cache as an interceptor with @Cached
Every interface that extends HttpClient and that contains methods annotated with @Request
Lets you define an HTTP client in a declarative manner using an annotated interface.
See the Using HttpClient for more details.
All these injected services are serializable, which is important for big data environments. If you create the instances yourself, you cannot benefit from these features, nor from the memory optimization done by the runtime. Prefer reusing the framework instances over custom ones.
The local configuration uses system properties and the environment (replacing dots per underscores) to look up the values. You can also put a TALEND-INF/local-configuration.properties file with default values. This allows to use the local_configuration:
The HTTP API intends to expose most Talend Component Kit features over HTTP. It is a standalone Java HTTP server.
The WebSocket protocol is activated for the endpoints. Endpoints then use /websocket/v1 as base instead of /api/v1. See WebSocket for more details.
Browse the API description using interface.
To make sure that the migration can be enabled, you need to set the version the component was created with in the execution configuration that you send to the server (component version is in component the detail endpoint). To do that, use tcomp::component::version key.
Endpoints that are intended to disappear will be deprecated. A X-Talend-Warning header will be returned with a message as value.
You can connect yo any endpoint by:
Replacing /api with /websocket
Appending /
Datasets and datastores are configuration types that define how and where to pull the data from. They are used at design time to create shared configurations that can be stored and used at runtime. All connectors (input and output components) created using Talend Component Kit must reference a valid dataset. Each dataset must reference a datastore. Datastore: The data you need to connect to the backend. Dataset: A datastore coupled with the data you need to execute an action. Make sure that: a datastore is used in each dataset. each dataset has a corresponding input component (mapper or emitter). This input component must be able to work with only the dataset part filled by final users. Any other property implemented for that component must be optional. These rules are enforced by the validateDataSet validation. If the conditions are not met, the component builds will fail. Make sure that: a datastore is used in each dataset. each dataset has a corresponding input component (mapper or emitter). This input component must be able to work with only the dataset part filled by final users. Any other property implemented for that component must be optional. These rules are enforced by the validateDataSet validation. If the conditions are not met, the component builds will fail. A datastore defines the information required to connect to a data source. For example, it can be made of: a URL a username a password. You can specify a datastore and its context of use (in which dataset, etc.) from the Component Kit Starter. Make sure to modelize the data your components are designed to handle before defining datasets and datastores in the Component Kit Starter. Once you generate and import the project into an IDE, you can find datastores under a specific datastore node. Example of datastore: A dataset represents the inbound data. It is generally made of: A datastore that defines the connection information needed to access the data. A query. You can specify a dataset and its context of use (in which input and output component it is used) from the Component Kit Starter. Make sure to modelize the data your components are designed to handle before defining datasets and datastores in the Component Kit Starter. Once you generate and import the project into an IDE, you can find datasets under a specific dataset node. Example of dataset referencing the datastore shown above: The display name of each dataset and datastore must be referenced in the message.properties file of the family package. The key for dataset and datastore display names follows a defined pattern: ${family}.${configurationType}.${name}._displayName. For example: These keys are automatically added for datasets and datastores defined from the Component Kit Starter. When deploying a component or set of components that include datasets and datastores to Talend Studio, a new node is created under Metadata. This node has the name of the component family that was deployed. It allows users to create reusable configurations for datastores and datasets. With predefined datasets and datastores, users can then quickly fill the component configuration in their jobs. They can do so by selecting Repository as Property Type and by browsing to the predefined dataset or datastore. Studio will generate connection and close components auto for reusing connection function in input and output components, just need to do like this example: Then the runtime mapper and processor only need to use @Connection to get the connection like this: The component server scans all configuration types and returns a configuration type index. This index can be used for the integration into the targeted platforms (Studio, web applications, and so on). Mark a model (complex object) as being a dataset. API: @org.talend.sdk.component.api.configuration.type.DataSet Sample: Mark a model (complex object) as being a datastore (connection to a backend). API: @org.talend.sdk.component.api.configuration.type.DataStore Sample: Mark a model (complex object) as being a dataset discovery configuration. API: @org.talend.sdk.component.api.configuration.type.DatasetDiscovery Sample: The component family associated with a configuration type (datastore/dataset) is always the one related to the component using that configuration. The configuration type index is represented as a flat tree that contains all the configuration types, which themselves are represented as nodes and indexed by ID. Every node can point to other nodes. This relation is represented as an array of edges that provides the child IDs. As an illustration, a configuration type index for the example above can be defined as follows:
The component API is declarative (through annotations) to ensure it is: Evolutive. It can get new features without breaking old code. As static as possible. Because it is fully declarative, any new API can be added iteratively without requiring any change to existing components. For example, in the case of Beam potential evolution: would not be affected by the addition of the new Timer API, which can be used as follows: The intent of the framework is to be able to fit in a Java UI as well as in a web UI. It must be understood as colocalized and remote UI. The goal is to move as much as possible the logic to the UI side for UI-related actions. For example, validating a pattern, a size, and so on, should be done on the client side rather than on the server side. Being static encourages this practice. The other goal of being static in the API definition is to ensure that the model will not be mutated at runtime and that all the auditing and modeling can be done before, at the design phase. Being static also ensures that the development can be validated as much as possible through build tools. This does not replace the requirement to test the components but helps developers to maintain components with automated tools. Refer to this document. The components must be able to execute even if they have conflicting libraries. For that purpose, classloaders must be isolated. A component defines its dependencies based on a Maven format and is always bound to its own classloader. The definition payload is as flat as possible and strongly typed to ensure it can be manipulated by consumers. This way, consumers can add or remove fields with simple mapping rules, without any abstract tree handling. The execution (runtime) configuration is the concatenation of framework metadata (only the version) and a key/value model of the instance of the configuration based on the definition properties paths for the keys. It enables consumers to maintain and work with the keys/values according to their need. The framework not being responsible for any persistence, it is very important to make sure that consumers can handle it from end to end, with the ability to search for values (update a machine, update a port and so on) and keys (for example, a new encryption rule on key certificate). Talend Component Kit is a metamodel provider (to build forms) and a runtime execution platform. It takes a configuration instance and uses it volatilely to execute a component logic. This implies it cannot own the data nor define the contract it has for these two endpoints and must let the consumers handle the data lifecycle (creation, encryption, deletion, and so on). A new mime type called talend/stream is introduced to define a streaming format. It matches a JSON object per line: Icons (@Icon) are based on a fixed set. Custom icons can be used but their display cannot be guaranteed. Components can be used in any environment and require a consistent look that cannot be guaranteed outside of the UI itself. Defining keys only is the best way to communicate this information. Once you know exactly how you will deploy your component in the Studio, then you can use `@Icon(value = CUSTOM, custom = "…") to use a custom icon file.
Some recommendations apply to the way component packages are organized: Make sure to create a package-info.java file with the component family/categories at the root of your component package: Create a package for the configuration. Create a package for the actions. Create a package for the component and one sub-package by type of component (input, output, processors, and so on). It is recommended to serialize your configuration in order to be able to pass it through other components. When building a new component, the first step is to identify the way it must be configured. The two main concepts are: The DataStore which is the way you can access the backend. The DataSet which is the way you interact with the backend. For example: Example description DataStore DataSet Accessing a relational database like MySQL JDBC driver, URL, username, password Query to execute, row mapper, and so on. Accessing a file system File pattern (or directory + file extension/prefix/…) File format, buffer size, and so on. It is common to have the dataset including the datastore, because both are required to work. However, it is recommended to replace this pattern by defining both dataset and datastore in a higher level configuration model. For example: Input and output components are particular because they can be linked to a set of actions. It is recommended to wire all the actions you can apply to ensure the consumers of your component can provide a rich experience to their users. The most common actions are the following ones: This action exposes a way to ensure the datastore/connection works. Configuration example: Action example: Until the studio integration is complete, it is recommended to limit processors to one input. Configuring processor components is simpler than configuring input and output components because it is specific for each component. For example, a mapper takes the mapping between the input and output models: It is recommended to provide as much information as possible to let the UI work with the data during its edition. Light validations are all the validations you can execute on the client side. They are listed in the UI hint section. Use light validations first before going with custom validations because they are more efficient. Custom validations enforce custom code to be executed, but are heavier to execute. Prefer using light validations when possible. Define an action with the parameters needed for the validation and link the option you want to validate to this action. For example, to validate a dataset for a JDBC driver: You can also define a Validable class and use it to validate a form by setting it on your whole configuration: The parameter binding of the validation method uses the same logic as the component configuration injection. Therefore, the @Option method specifies the prefix to use to reference a parameter. It is recommended to use @Option("value") until you know exactly why you don’t use it. This way, the consumer can match the configuration model and just prefix it with value. to send the instance to validate. Validations are triggers based on "events". If you mark part of a configuration as @Validable but this configuration is translated to a widget without any interaction, then no validation will happen. The rule of thumb is to mark only primitives and simple types (list of primitives) as @Validable. It can be handy and user-friendly to provide completion on some fields. For example, to define completion for available drivers: Each component must have its own icon: You can use talend.surge.sh/icons/ to find the icon you want to use. It is recommended to enforce the version of your component, event though it is not mandatory for the first version. If you break a configuration entry in a later version; make sure to: Upgrade the version. Support a migration of the configuration. Testing your components is critical. You can use unit and simple standalone JUnit tests, but it is also highly recommended to have Beam tests in order to make sure that your component works in Big Data.
The Talend Component Kit IntelliJ plugin is a plugin for the IntelliJ Java IDE. It adds support for the Talend Component Kit project creation. Main features: Project generation support. Internationalization completion for component configuration. In the Intellij IDEA: Go to File > Settings… On the left panel, select Plugins. Access the Marketplace tab. Enter Talend in the search field and Select Talend Component Kit. Select Install. Click the Restart IDE button. Confirm the IDEA restart to complete the installation. The plugin is now installed on your IntelliJ IDEA. You can start using it. The plugin offers auto-completion for the configuration internationalization. The Talend component configuration lets you setup translatable and user-friendly labels for your configuration using a property file. Auto-completion in possible for the configuration keys and default values in the property file. For example, you can internationalize a simple configuration class for a basic authentication that you use in your component: This configuration class contains three properties which you can attach a user-friendly label to. For example, you can define a label like My server URL for the url option: Locate or create a Messages.properties file in the project resources and add the label to that file. The plugin automatically detects your configuration and provides you with key completion in the property file. Press Ctrl+Space to see the key suggestions.
Processors and output components are the components in charge of reading, processing and transforming data in a Talend job, as well as passing it to its required destination.
Before implementing the component logic and defining its layout and configurable fields, make sure you have specified its basic metadata, as detailed in this document.
A Processor is a component that converts incoming data to a different model.
A processor must have a method decorated with @ElementListener taking an incoming data and returning the processed data:
Processors must be Serializable because they are distributed components.
If you just need to access data on a map-based ruleset, you can use Record or JsonObject as parameter type. From there, Talend Component Kit wraps the data to allow you to access it as a map. The parameter type is not enforced. This means that if you know you will get a SuperCustomDto, then you can use it as parameter type. But for generic components that are reusable in any chain, it is highly encouraged to use Record until you have an evaluation language-based processor that has its own way to access components.
For example:
A processor also supports @BeforeGroup and @AfterGroup methods, which must not have any parameter and return void values. Any other result would be ignored. These methods are used by the runtime to mark a chunk of the data in a way which is estimated good for the execution flow size.
Because the size is estimated, the size of a group can vary. It is even possible to have groups of size 1.
It is recommended to batch records, for performance reasons:
You can optimize the data batch processing by using the maxBatchSize parameter. This parameter is automatically implemented on the component when it is deployed to a Talend application. Only the logic needs to be implemented. You can however customize its value setting in your LocalConfiguration the property _maxBatchSize.value - for the family - or ${component simple class name}._maxBatchSize.value - for a particular component, otherwise its default will be 1000. If you replace value by active, you can also configure if this feature is enabled or not. This is useful when you don’t want to use it at all. Learn how to implement chunking/bulking in this document.
In some cases, you may need to split the output of a processor in two or more connections. A common example is to have "main" and "reject" output connections where part of the incoming data are passed to a specific bucket and processed later.
Talend Component Kit supports two types of output connections: Flow and Reject.
Flow is the main and standard output connection.
The Reject connection handles records rejected during the processing. A component can only have one reject connection, if any. Its name must be REJECT to be processed correctly in Talend applications.
You can also define the different output connections of your component in the Starter.
To define an output connection, you can use @Output as replacement of the returned value in the @ElementListener:
Alternatively, you can pass a string that represents the new branch:
Having multiple inputs is similar to having multiple outputs, except that an OutputEmitter wrapper is not needed:
@Input takes the input name as parameter. If no name is set, it defaults to the "main (default)" input branch. It is recommended to use the default branch when possible and to avoid naming branches according to the component semantic.
Batch processing refers to the way execution environments process batches of data handled by a component using a grouping mechanism.
By default, the execution environment of a component automatically decides how to process groups of records and estimates an optimal group size depending on the system capacity. With this default behavior, the size of each group could sometimes be optimized for the system to handle the load more effectively or to match business requirements.
For example, real-time or near real-time processing needs often imply processing smaller batches of data, but more often. On the other hand, a one-time processing without business contraints is more effectively handled with a batch size based on the system capacity.
Final users of a component developed with the Talend Component Kit that integrates the batch processing logic described in this document can override this automatic size. To do that, a maxBatchSize option is available in the component settings and allows to set the maximum size of each group of data to process.
A component processes batch data as follows:
Case 1 - No maxBatchSize is specified in the component configuration. The execution environment estimates a group size of 4. Records are processed by groups of 4.
Case 2 - The runtime estimates a group size of 4 but a maxBatchSize of 3 is specified in the component configuration. The system adapts the group size to 3. Records are processed by groups of 3.
Batch processing relies on the sequence of three methods: @BeforeGroup, @ElementListener, @AfterGroup, that you can customize to your needs as a component Developer.
The group size automatic estimation logic is automatically implemented when a component is deployed to a Talend application.
Each group is processed as follows until there is no record left:
The @BeforeGroup method resets a record buffer at the beginning of each group.
The records of the group are assessed one by one and placed in the buffer as follows: The @ElementListener method tests if the buffer size is greater or equal to the defined maxBatchSize. If it is, the records are processed. If not, then the current record is buffered.
The previous step happens for all records of the group. Then the @AfterGroup method tests if the buffer is empty.
You can define the following logic in the processor configuration:
You can also use the condensed syntax for this kind of processor:
When writing tests for components, you can force the maxBatchSize parameter value by setting it with the following syntax:
Standalone components are the components without input or output flows. They are designed to do actions without reading or processing any data. For example standalone components can be used to create indexes in databases. Before implementing the component logic and defining its layout and configurable fields, make sure you have specified its basic metadata, as detailed in this document. A Driver Runner (DriverRunner) is a standalone component which doesn’t process or return any data. A Driver runner must have a @RunAtDriver method without any parameter.
Input components are the components generally placed at the beginning of a Talend job. They are in charge of retrieving the data that will later be processed in the job.
An input component is primarily made of three distinct logics:
The execution logic of the component itself, defined through a partition mapper.
The configurable part of the component, defined through the mapper configuration.
The source logic defined through a producer.
Before implementing the component logic and defining its layout and configurable fields, make sure you have specified its basic metadata, as detailed in this document.
A Partition Mapper (PartitionMapper) is a component able to split itself to make the execution more efficient.
This concept is borrowed from big data and useful in this context only (BEAM executions). The idea is to divide the work before executing it in order to reduce the overall execution time.
The process is the following:
The size of the data you work on is estimated. This part can be heuristic and not very precise.
From that size, the execution engine (runner for Beam) requests the mapper to split itself in N mappers with a subset of the overall work.
The leaf (final) mapper is used as a Producer (actual reader) factory.
This kind of component must be Serializable to be distributable.
A partition mapper requires three methods marked with specific annotations:
@Assessor for the evaluating method
@Split for the dividing method
@Emitter for the Producer factory
The Assessor method returns the estimated size of the data related to the component (depending its configuration). It must return a Number and must not take any parameter.
For example:
The Split method returns a collection of partition mappers and can take optionally a @PartitionSize long value as parameter, which is the requested size of the dataset per sub partition mapper.
For example:
The Emitter method must not have any parameter and must return a producer. It uses the partition mapper configuration to instantiate and configure the producer.
For example:
The Producer defines the source logic of an input component. It handles the interaction with a physical source and produces input data for the processing flow.
A producer must have a @Producer method without any parameter. It is triggered by the @Emitter method of the partition mapper and can return any data. It is defined in the
This tutorial walks you through the most common iteration steps to create a component with Talend Component Kit and to deploy it to Talend Open Studio.
The component created in this tutorial is a simple processor that reads data coming from the previous component in a job or pipeline and displays it in the console logs of the application, along with an additional information entered by the final user.
The component designed in this tutorial is a processor and does not require nor show any datastore and dataset configuration. Datasets and datastores are required only for input and output components.

Make sure that a Project SDK is selected. Then, select Talend Component and click Next. The Talend Component Kit Starter opens.
Enter the component and project metadata. Change the default values, for example as presented in the screenshot below:
The Component Family and the Category will be used later in Talend Open Studio to find the new component.
Project metadata is mostly used to identify the project structure. A common practice is to replace 'company' in the default value by a value of your own, like your domain name.
Once the metadata is filled, select Add a component. A new screen is displayed in the Talend Component Kit Starter that lets you define the generic configuration of the component. By default, new components are processors.
Enter a valid Java name for the component. For example, Logger.
Select Configuration Model and add a string type field named level. This input field will be used in the component configuration for final users to enter additional information to display in the logs.
In the Input(s) / Output(s) section, click the default MAIN input branch to access its detail, and make sure that the record model is set to Generic. Leave the Name of the branch with its default MAIN value.
Repeat the same step for the default MAIN output branch.
Because the component is a processor, it has an output branch by default. A processor without any output branch is considered an output component. You can create output components when the Activate IO option is selected.
Click Next and check the name and location of the project, then click Finish to generate the project in the IDE.
At this point, your component is technically already ready to be compiled and deployed to Talend Open Studio. But first, take a look at the generated project:
Two classes based on the name and type of component defined in the Talend Component Kit Starter have been generated:
LoggerProcessor is where the component logic is defined
LoggerProcessorConfiguration is where the component layout and configurable fields are defined, including the level string field that was defined earlier in the configuration model of the component.
The package-info.java file contains the component metadata defined in the Talend Component Kit Starter, such as family and category.
You can notice as well that the elements in the tree structure are named after the project metadata defined in the Talend Component Kit Starter.
These files are the starting point if you later need to edit the configuration, logic, and metadata of the component.
There is more that you can do and configure with the Talend Component Kit Starter. This tutorial covers only the basics. You can find more information in this document.
Without modifying the component code generated from the Starter, you can compile the project and deploy the component to a local instance of Talend Open Studio.
The logic of the component is not yet implemented at that stage. Only the configurable part specified in the Starter will be visible. This step is useful to confirm that the basic configuration of the component renders correctly.
Before starting to run any command, make sure that Talend Open Studio is not running.
From the component project in IntelliJ, open a Terminal and make sure that the selected directory is the root of the project. All commands shown in this tutorial are performed from this location.
Compile the project by running the following command: mvnw clean install. The mvnw command refers to the Maven wrapper that is embedded in Talend Component Kit. It allows to use the right version of Maven for your project without having to install it manually beforehand. An equivalent wrapper is available for Gradle.
Once the command is executed and you see BUILD SUCCESS in the terminal, deploy the component to your local instance of Talend Open Studio using the following command: mvnw talend-component:deploy-in-studio -Dtalend.component.studioHome="
Components built using Talend Component Kit can be shared as component archives (.car). These CAR files are executable files allowing to easily deploy the components it contains to any compatible version of Talend Studio. Component developers can generate .car files from their projects to share their components and make them available for other users, as detailed in this document. This document assumes that you have a component archive (.car) file and need to deploy it to Talend Studio. The component archive (.car) is executable and exposes the studio-deploy command which takes a Talend Studio home path as parameter. When executed, it installs the dependencies into the Studio and registers the component in your instance. For example: You can also upload the dependencies to your Nexus server using the following command: In this command, Nexus URL and repository name are mandatory arguments. All other arguments are optional. If arguments contain spaces or special symbols, you need to quote the whole value of the argument. For example: Talend Studio allows you to share components you have created using Talend Component Kit to other users working on the same remote project. Remote projects are available with Enterprise versions of Talend Studio only. Also, note that this feature has been removed in Studio since 7.3 release. Make sure you are connected to a remote project and the artifact repository for component sharing has been properly configured. On the toolbar of the Studio main window, click or click File > Edit Project Properties from the menu bar to open the Project Settings dialog box. In the tree view of the dialog box, select Repository Share to open the corresponding view. Select the Propagate components update to Artifact Repository check box. In the Repository ID field, specify the artifact repository configured for component sharing, and then click Check connection to verify the connectivity. Click Apply and Close to validate the settings and close the dialog box. Create a folder named patches at the root of your Talend Studio installation directory, then copy the .car files of the components you want share to this folder. Restart your Talend Studio and connect to the remote project. The components are deployed automatically to the repository and available in the Palette for other users when connected to a remote project with the same sharing repository configuration. My custom component builds correctly but does not appear in Talend Studio, how to fix it? This issue can be caused by the icon specified in the component metadata. Make sure to specify a custom icon for the component and the component family. These custom icons must be in PNG format to be properly handled by Talend Studio. Remove SVG parameters from the talend.component.server.icon.paths property in the HTTP server configuration. Refer to this section. Learn more about defining custom icons for components in this document.
This tutorial shows how to adapt the test configuration of the Zendesk search component that was done in this previous tutorial to make it work in a Continuous Integration environment.
In the test, the Zendesk credentials are used directly in the code to perform a first capture of the API response. Then, fake credentials are used in the simulation mode because the real API is not called anymore.
However, in some cases, you can require to continue calling the real API on a CI server or on a specific environment.
To do that, you can adapt the test to get the credentials depending on the execution mode (simulation/passthrough).
These instructions concern the CI server or on any environment that requires real credentials.
This tutorial uses:
A Maven server that supports password encryption as a credential provider. Encryption is optional but recommended.
The MavenDecrypterRule test rule provided by the framework. This rule lets you get credentials from Maven settings using a server ID.
To create encrypted server credentials for the Zendesk instance:
Create a master password using the command: mvn --encrypt-master-password
By default, input components are designed to receive a one-time batch of data to process. By enabling the streaming mode, you can instead set your component to process a continuous incoming flow of data.
When streaming is enabled on an input component, the component tries to pull data from its producer. When no data is pulled, it waits for a defined period of time before trying to pull data again, and so on. This period of time between tries is defined by a strategy.
This document explains how to configure this strategy and the cases where it can fit your needs.
Before enabling streaming on your component, make sure that it fits the scope and requirements of your project and that regular batch processing cannot be used instead.
Streaming is designed to help you dealing with real-time or near real-time data processing cases, and should be used only for such cases. Enabling streaming will impact the performance when processing batches of data.
You can enable streaming right from the design phase of the project by enabling the Stream toggle in the basic configuration of your future component in the Component Kit Starter.
Doing so adds a default streaming-ready configuration to your component when generating the project. This default configuration implements a constant pause duration of 500 ms between retries, with no limit of retries.
Without any configuration, streaming components have an infinite lifecycle and will never stop. Sometimes, you may need to stop component after a certain amount of records read or time elapsed.
You can add configuration that helps you to stop the data reading in your input component when it reaches required limitations. To enable it you need to set true in PartitionMapper#stoppable. An important condition is that PartitionMapper#infinite should also be true.
Here’s a sample code:
There are two reading stop conditions (can be combined):
maxDurationMs : stop after n milliseconds elapsed.
maxRecords : stop after n records read.
See next subsections for configuring those values.
If you choose to use a stoppable streaming component, you will have certainly to adapt your code according the backend technology and how to read values. For instance, if in your component you read 100 values at once and the maxRecords value is 50, you may lose 50 values (if the 100 values were acknowledged).
In that case, to build a correct strategy in your component, you can access to stop condition values. To access these informations use the @PostConstruct method with @Option annotation in your Emitter class.
Available options:
Option.MAX_DURATION_PARAMETER : reflects the maxDurationMs parameter.
Option.MAX_RECORDS_PARAMETER : reflects the maxRecords parameter.
Here a code sample:
If your streaming connector (infinite=true) is defined with the stoppable=true, you will have a design time UI for specifying stop strategy:
Cloud
Studio
By default, in the setting those values are set to -1. It means infinity behavior.
At runtime, you can set system properties to apply the strategy. You need to prefix properties with the component’s family.
It is possible to extend the Component API for custom front features. What is important here is to keep in mind that you should do it only if it targets not portable components (only used by the Studio or Beam). It is recommended to create a custom xxxx-component-api module with the new set of annotations. To extend the UI, add an annotation that can be put on @Option fields, and that is decorated with @Ui. All its members are then put in the metadata of the parameter. For example:
To develop new components, Talend Component Kit requires a build tool in which you will import the component project generated from the starter.
You will then be able to install and deploy it to Talend applications. A Talend Component Kit plugin is available for each of the supported build tools.
talend-component-maven-plugin helps you write components that match best practices and generate transparently metadata used by Talend Studio.
You can use it as follows:
This plugin is also an extension so you can declare it in your build/extensions block as:
Used as an extension, the goals detailed in this document will be set up.
The Talend Component Kit plugin integrates some specific goals within Maven build lifecycle. For example, to compile the project and prepare for deploying your component, run mvn clean install. Using this command, the following goals are executed:
The build is split into several phases. The different goals are executed in the order shown above. Talend Component Kit uses default goals from the Maven build lifecycle and adds additional goals to the building and packaging phases.
Goals added to the build by Talend Component Kit are detailed below. The default lifecycle is detailed in Maven documentation.
The Talend Component Kit plugin for Maven integrates several specific goals into Maven build lifecycle.
To run specific goals individually, run the following command from the root of the project, by adapting it with each goal name, parameters and values:
The first goal is a shortcut for the maven-dependency-plugin. It creates the TALEND-INF/dependencies.txt file with the compile and runtime dependencies, allowing the component to use it at runtime:
The scan-descriptor goal scans the current module and optionally other configured folders to precompute the list of interesting classes for the framework (components, services). It allows to save some bootstrap time when launching a job, which can be useful in some execution cases:
Configuration - excluding parameters used by default only:
Name
Description
User property
Default
output
Where to dump the scan result. Note: It is not supported to change that value in the runtime.
talend.scan.output
${project.build.outputDirectory}/TALEND-INF/scanning.properties
scannedDirectories
Explicit list of directories to scan.
talend.scan.scannedDirectories
If not set, defaults to ${project.build.outputDirectory}
scannedDependencies
Explicit list of dependencies to scan - set them in the groupId:artifactId format. The list is appended to the file to scan.
talend.scan.scannedDependencies
-
The svg2png goal scans a directory - default to target/classes/icons - to find .svg files and copy them in a PNG version size at 32x32px and named with the suffix _icon32.png to enable the studio to read it:
Configuration:
Name
Description
User property
Default
icons
Where to scan for the SVG icons to convert in PNG.
talend.icons.source
${project.build.outputDirectory}/icons
workarounds
By default the shape of the icon will be enforce in the RGB channels (in white) using the alpha as reference. This is useful for black/white images using alpha to shape the picture because Eclipse - Talend Studio - caches icons using RGB but not alpha channel, pictures not using alpha channel to draw their shape should disable that workaround.
talend.icons.workaround
true
if you use that plugin, ensure to set it before the validate mojo otherwise validation can miss some png files.
This goal helps you validate the common programming model of the component. To activate it, you can use following execution definition:
It is bound to the process-classes phase by default. When executed, it performs several validations that can be disabled by setting the corresponding flags to false in the
This part is limited to specific kinds of Beam PTransform:

Testing code that consumes REST APIs can sometimes present many constraints: API rate limit, authentication token and password sharing, API availability, sandbox expiration, API costs, and so on. As a developer, it becomes critical to avoid those constraints and to be able to easily mock the API response. The component framework provides an API simulation tool that makes it easy to write unit tests. This tutorial shows how to use this tool in unit tests. As a starting point, the tutorial uses the component that consumes Zendesk Search API and that was created in a previous tutorial. The goal is to add unit tests for it. For this tutorial, four tickets that have the open status have been added to the Zendesk test instance used in the tests. To learn more about the testing methodology used in this tutorial, refer to Component JUnit testing. Create a unit test that performs a real HTTP request to the Zendesk Search API instance. You can learn how to create a simple unit test in this tutorial. the authentication configuration using Zendesk instance URL and credentials. the search query configuration to get all the open ticket, ordered by creation date and sorted in descending order. The test is now complete and working. It performs a real HTTP request to the Zendesk instance. As an alternative, you can use mock results to avoid performing HTTP requests every time on the development environment. The real HTTP requests would, for example, only be performed on an integration environment. To transform the unit test into a mocked test that uses a mocked response of the Zendesk Search API: Add the two following JUnit rules provided by the component framework. JUnit4HttpApi: This rule starts a simulation server that acts as a proxy and catches all the HTTP requests performed in the tests. This simulation server has two modes : capture : This mode forwards the captured HTTP request to the real server and captures the response. simulation : this mode returns a mocked response from the responses already captured. This rule needs to be added as a class rule. JUnit4HttpApi: This rule has a reference to the first rule. Its role is to configure the simulation server for every unit test. It passes the context of the running test to the simulation server. This rule needs to be added as a simple (method) rule. Example to run in a simulation mode: Make the test run in capture mode to catch the real API responses that can be used later in the simulated mode. To do that, set a new talend.junit.http.capture environment variable to true. This tells the simulation server to run in a capture mode. The captured response is saved in the resources/talend.testing.http package in a JSON format, then reused to perform the API simulation.
This tutorial walks you through the creation, from scratch, of a complete Talend input component for Hazelcast using the Talend Component Kit (TCK) framework.
Hazelcast is an in-memory distributed system that can store data, which makes it a good example of input component for distributed systems. This is enough for you to get started with this tutorial, but you can find more information about it here: hazelcast.org/.
A TCK project is a simple Java project with specific configurations and dependencies. You can choose your preferred build tool from Maven or Gradle as TCK supports both. In this tutorial, Maven is used.
The first step consists in generating the project structure using Talend Starter Toolkit .
Go to starter-toolkit.talend.io/ and fill in the project information as shown in the screenshots below, then click Finish and Download as ZIP.
image::tutorial_hazelcast_generateproject_1.png[] image::tutorial_hazelcast_generateproject_2.png[]
Extract the ZIP file into your workspace and import it to your preferred IDE. This tutorial uses Intellij IDE, but you can use Eclipse or any other IDE that you are comfortable with.
You can use the Starter Toolkit to define the full configuration of the component, but in this tutorial some parts are configured manually to explain key concepts of TCK.
The generated pom.xml file of the project looks as follows:
Change the name tag to a more relevant value, for example:
To develop new components, Talend Component Kit requires a build tool in which you will import the component project generated from the starter. With this build tool, you will also be able to implement the logic of your component and to install and deploy it to Talend applications. A Talend Component Kit plugin is available for each of the supported build tools. gradle-talend-component helps you write components that match the best practices. It is inspired from the Maven plugin and adds the ability to generate automatically the dependencies.txt file used by the SDK to build the component classpath. For more information on the configuration, refer to the Maven properties matching the attributes. By default, Gradle does not log information messages. To see messages, use --info in your commands. Refer to Gradle’s documentation to learn about log levels. You can use it as follows:
The Remote Engine is a key piece for executing components with Talend Pipeline Designer. To customize it for testing purposes, a helper tool is available. The following content and the tool it describes are not officially supported as a Talend Cloud feature and are provided "as it" without any guarantee. The remote-engine-customizer is a simple tool that reads the Remote Engine docker-compose.yml file, extracts the connectors image and rebuilds it adding configured connectors to the image. By default, it replaces the original image with the newly built one and saves the old file in the .remote_engine_customizer/backup/ directory of the Remote Engine. The customizer is provided as a docker container. You can run the tool using the register-component-archive command: You can get more details about the tool with the following command: You can find out all the available versions at hub.docker.com/r/tacokit/remote-engine-customizer/tags. The command accepts the following parameters: When running using the docker container, you must mount several files/folders. For example: Once you have built the new image, you must restart the Remote Engine. You can verify that the new image is available by running docker run --entrypoint sh -it [newimage] before.
