Since the 1.1.25 release, the dynamic column feature is supported in Studio with component-runtime components. Dynamic column is available with Enterprise versions of Talend Studio only. In Studio, we can define for each component a schema with associated metadata. To access those informations in your component, you’ve to do a few things: Using the @Structure annotation API: @org.talend.sdk.component.api.configuration.ui.widget.Structure According the specified field type, you will acess to the column names list with List a subset or all wanted metadata with List (see below) Then, we should have a class SchemaInfo as following: Defining a specific class for holding metadata If you don’t want just only column names (using List), you’ll have to define a custom class. Available Studio metadata informations Field name Type Name in Studio label String Column originalDbColumnName String Db Column key Boolean Key type String DB Type talendType String Type nullable Boolean Nullable pattern String Date Pattern length int Length precision int Precision defaultValue String Default comment String Comment Available since 1.43.x release As Talend Component Kit Schema's types aren’t matching all Studio types, we wrap those types in wider types (like Character or char wrapped into String, Short to Integer, and so on…). Anyway, the original type coming from Studio’s IPersistableRow is stored in record’s schema properties under the property name talend.studio.type. Studio managed types are: id_BigDecimal, id_Boolean, id_Byte, id_byte[], id_Character, id_Date, id_Double, id_Document, id_Dynamic, id_Float, id_Integer, id_List, id_Long, id_Object, id_Short, id_String. When handling an output connector designed for Studio, you should have to check for this property to get an accurate type for output. For instance, java.math.BigDecimal is handled in framework as a Type.STRING, so when an output connector will receive a record, in studio context, you’ll need to check for the property and cast it correctly. Here is a simple processor before writing to backend destination: This usage of properties is cumbersome but may fix some potential issues for now. We plan to widen managed types in Record and Schema in a few iterations (No ETA defined yet).

The component configuration is defined in the Configuration.java file of the package. It consists in defining the configurable part of the component that will be displayed in the UI. To do that, you can specify parameters. When you import the project in your IDE, the parameters that you have specified in the starter are already present. All input and output components must reference a dataset in their configuration. Refer to Defining datasets and datastores. Components are configured using their constructor parameters. All parameters can be marked with the @Option property, which lets you give a name to them. For the name to be correct, you must follow these guidelines: Use a valid Java name. Do not include any . character in it. Do not start the name with a $. Defining a name is optional. If you don’t set a specific name, it defaults to the bytecode name. This can require you to compile with a -parameter flag to avoid ending up with names such as arg0, arg1, and so on. Examples of option name: Option name Valid myName my_name my.name $myName Parameter types can be primitives or complex objects with fields decorated with @Option exactly like method parameters. It is recommended to use simple models which can be serialized in order to ease serialized component implementations. For example: Using this kind of API makes the configuration extensible and component-oriented, which allows you to define all you need. The instantiation of the parameters is done from the properties passed to the component. A primitive is a class which can be directly converted from a String to the expected type. It includes all Java primitives, like the String type itself, but also all types with a org.apache.xbean.propertyeditor.Converter: BigDecimal BigInteger File InetAddress ObjectName URI URL Pattern LocalDateTime ZonedDateTime The conversion from property to object uses the Dot notation. For example, assuming the method parameter was configured with @Option("file"): matches Lists rely on an indexed syntax to define their elements. For example, assuming that the list parameter is named files and that the elements are of the FileOptions type, you can define a list of two elements as follows: if you desire to override a config to truncate an array, use the index length, for example to truncate previous example to only CSV, you can set: Similarly to the list case, the map uses .key[index] and .value[index] to represent its keys and values: Avoid using the Map type. Instead, prefer configuring your component with an object if this is possible. You can use metadata to specify that a field is required or has a minimum size, and so on. This is done using the validation metadata in the org.talend.sdk.component.api.configuration.constraint package: Ensure the decorated option size is validated with a higher bound. API: @org.talend.sdk.component.api.configuration.constraint.Max Name: maxLength Parameter Type: double Supported Types: — java.lang.CharSequence Sample: Ensure the decorated option size is validated with a lower bound. API: @org.talend.sdk.component.api.configuration.constraint.Min Name: minLength Parameter Type: double Supported Types: — java.lang.CharSequence Sample: Validate the decorated string with a javascript pattern (even into the Studio). API: @org.talend.sdk.component.api.configuration.constraint.Pattern Name: pattern Parameter Type: java.lang.string Supported Types: — java.lang.CharSequence Sample: Ensure the decorated option size is validated with a higher bound. API: @org.talend.sdk.component.api.configuration.constraint.Max Name: max Parameter Type: double Supported Types: — java.lang.Number — int — short — byte — long — double — float Sample: Ensure the decorated option size is validated with a lower bound. API: @org.talend.sdk.component.api.configuration.constraint.Min Name: min Parameter Type: double Supported Types: — java.lang.Number — int — short — byte — long — double — float Sample: Mark the field as being mandatory. API: @org.talend.sdk.component.api.configuration.constraint.Required Name: required Parameter Type: - Supported Types: — java.lang.Object Sample: Ensure the decorated option size is validated with a higher bound. API: @org.talend.sdk.component.api.configuration.constraint.Max Name: maxItems Parameter Type: double Supported Types: — java.util.Collection Sample: Ensure the decorated option size is validated with a lower bound. API: @org.talend.sdk.component.api.configuration.constraint.Min Name: minItems Parameter Type: double Supported Types: — java.util.Collection Sample: Ensure the elements of the collection must be distinct (kind of set). API: @org.talend.sdk.component.api.configuration.constraint.Uniques Name: uniqueItems Parameter Type: - Supported Types: — java.util.Collection Sample: When using the programmatic API, metadata is prefixed by tcomp::. This prefix is stripped in the web for convenience, and the table above uses the web keys. Also note that these validations are executed before the runtime is started (when loading the component instance) and that the execution will fail if they don’t pass. If it breaks your application, you can disable that validation on the JVM by setting the system property talend.component.configuration.validation.skip to true. 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.

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: If you need to define a binding between properties, you can use a set of annotations: If the evaluation of the element at the location matches value then the element is considered active, otherwise it is deactivated. API: @org.talend.sdk.component.api.configuration.condition.ActiveIf Type: if Sample: Allows to set multiple visibility conditions on the same property. API: @org.talend.sdk.component.api.configuration.condition.ActiveIfs Type: ifs Sample: Where: target is the element to evaluate. value is the value to compare against. strategy (optional) is the evaluation criteria. Possible values are: CONTAINS: Checks if a string or list of strings contains the defined value. DEFAULT: Compares against the raw value. LENGTH: For an array or string, evaluates the size of the value instead of the value itself. negate (optional) defines if the test must be positive (default, set to false) or negative (set to true). operator (optional) is the comparison operator used to combine several conditions, if applicable. Possible values are AND and OR. The target element location is specified as a relative path to the current location, using Unix path characters. The configuration class delimiter is /. The parent configuration class is specified by ... Thus, ../targetProperty denotes a property, which is located in the parent configuration class and is named targetProperty. When using the programmatic API, metadata is prefixed with tcomp::. This prefix is stripped in the web for convenience, and the previous table uses the web keys. For more details, refer to the related Javadocs. A common use of the ActiveIf condition consists in testing if a target property has a value. To do that, it is possible to test if the length of the property value is different from 0: target: foo - the path to the property to evaluate. strategy: LENGTH - the strategy consists here in testing the length of the property value. value: 0 - the length of the property value is compared to 0. negate: true - setting negate to true means that the strategy of the target must be different from the value defined. In this case, the LENGTH of the value of the foo property must be different from 0. The following example shows how to implement visibility conditions on several fields based on several checkbox configurations: If the first checkbox is selected, an additional input field is displayed. if the second or the third checkbox is selected, an additional input field is displayed. if both second and third checkboxes are selected, an additional input field is displayed. In some cases, you may need to add metadata about the configuration to let the UI render that configuration properly. For example, a password value that must be hidden and not a simple clear input box. For these cases - if you want to change the UI rendering - you can use a particular set of annotations: Provide a default value the UI can use - only for primitive fields. API: @org.talend.sdk.component.api.configuration.ui.DefaultValue Allows to sort a class properties. API: @org.talend.sdk.component.api.configuration.ui.OptionsOrder Request the rendered to do what it thinks is best. API: @org.talend.sdk.component.api.configuration.ui.layout.AutoLayout Advanced layout to place properties by row, this is exclusive with @OptionsOrder. the logic to handle forms (gridlayout names) is to use the only layout if there is only one defined, else to check if there are Main and Advanced and if at least Main exists, use them, else use all available layouts. API: @org.talend.sdk.component.api.configuration.ui.layout.GridLayout Allow to configure multiple grid layouts on the same class, qualified with a classifier (name) API: @org.talend.sdk.component.api.configuration.ui.layout.GridLayouts Put on a configuration class it notifies the UI an horizontal layout is preferred. API: @org.talend.sdk.component.api.configuration.ui.layout.HorizontalLayout Put on a configuration class it notifies the UI a vertical layout is preferred. API: @org.talend.sdk.component.api.configuration.ui.layout.VerticalLayout Mark a field as being represented by some code widget (vs textarea for instance). API: @org.talend.sdk.component.api.configuration.ui.widget.Code Mark a field as being a credential. It is typically used to hide the value in the UI. API: @org.talend.sdk.component.api.configuration.ui.widget.Credential Mark a field as being a date. It supports and is implicit - which means you don’t need to put that annotation on the option - for java.time.ZonedDateTime, java.time.LocalDate and java.time.LocalDateTime and is unspecified for other types. API: @org.talend.sdk.component.api.configuration.ui.widget.DateTime Mark a List or List

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 / to the URL Formatting the request as: For example: The response is formatted as follows: All endpoints are logged at startup. You can then find them in the logs if you have a doubt about which one to use. If you don’t want to create a pool of connections per endpoint/verb, you can use the bus endpoint: /websocket/v1/bus. This endpoint requires that you add the destinationMethod header to each request with the verb value (GET by default): the configuration is read from system properties, environment variables, …. Default value: 1000. Maximum items a cache can store, used for index endpoints. A comma separated list of gav to locate the components Default value: ${home}/documentations. A component translation repository. This is where you put your documentation translations. Their name must follow the pattern documentation_${container-id}_language.adoc where ${container-id} is the component jar name (without the extension and version, generally the artifactId). Default value: true. Should the component extensions add required dependencies. If you deploy some extension, where they can create their dependencies if needed. Default value: 180000. Timeout for extension initialization at startup, since it ensures the startup wait extensions are ready and loaded it allows to control the latency it implies. A property file (or multiple comma separated) where the value is a gav of a component to register(complementary with coordinates). Note that the path can end up with or .properties to take into account all properties in a folder. Default value: true. Should the /documentation endpoint be activated. Note that when called on localhost the doc is always available. Default value: true. Should the /api/v1/environment endpoint be activated. It shows some internal versions and git commit which are not always desirable over the wire. Default value: false. Should the components using a @GridLayout support tab translation. Studio does not suppot that feature yet so this is not enabled by default. Default value: icons/%s.svg,icons/svg/%s.svg,icons/%s_icon32.png,icons/png/%s_icon32.png. These patterns are used to find the icons in the classpath(s). Default value: false. If set it will replace any message for exceptions. Set to false to use the actual exception message. Default value: false. Should the lastUpdated timestamp value of /environment endpoint be updated with server start time. Default value: en*=en fr*=fr zh*=zh_CN ja*=ja de*=de. For caching reasons the goal is to reduce the locales to the minimum required numbers. For instance we avoid fr and fr_FR which would lead to the same entries but x2 in terms of memory. This mapping enables that by whitelisting allowed locales, default being en. If the key ends with it means all string starting with the prefix will match. For instance fr will match fr_FR but also fr_CA. The local maven repository used to locate components and their dependencies Default value: false. Should the plugins be un-deployed and re-deployed. Default value: 600. Interval in seconds between each check if plugins re-loading is enabled. Specify a file to check its timestamp on the filesystem. This file will take precedence of the default ones provided by the talend.component.server.component.registry property (used for timestamp method). Default value: timestamp. Re-deploy method on a timestamp or connectors version change. By default, the timestamp is checked on the file pointed by talend.component.server.component.registry or talend.component.server.plugins.reloading.marker variable, otherwise we inspect the content of the connectorS_VERSION file. Accepted values: timestamp, anything else defaults to connectors. Default value: false. Should the all requests/responses be logged (debug purposes - only work when running with CXF). Default value: securityNoopHandler. How to validate a command/request. Accepted values: securityNoopHandler. Default value: securityNoopHandler. How to validate a connection. Accepted values: securityNoopHandler. A folder available for the server - don’t forget to mount it in docker if you are using the image - which accepts subfolders named as component plugin id (generally the artifactId or jar name without the version, ex: jdbc). Each family folder can contain: a user-configuration.properties file which will be merged with component configuration system (see services). This properties file enables the function userJar(xxxx) to replace the jar named xxxx by its virtual gav (groupId:artifactId:version), a list of jars which will be merged with component family classpath Default value: auto. Should the implicit artifacts be provisionned to a m2. If set to auto it tries to detect if there is a m2 to provision - recommended, if set to skip it is ignored, else it uses the value as a m2 path. The configuration uses Microprofile Config for most entries. It means it can be passed through system properties and environment variables (by replacing dots with underscores and making the keys uppercase). To configure a Docker image rather than a standalone instance, Docker Config and secrets integration allows you to read the configuration from files. You can customize the configuration of these integrations through system properties. Docker integration provides a secure: support to encrypt values and system properties, when required. It is fully implemented using the Apache Geronimo Microprofile Config extensions. Using the server ZIP (or Docker image), you can configure HTTPS by adding properties to _JAVA_OPTIONS. Assuming that you have a certificate in /opt/certificates/component.p12 (don’t forget to add/mount it in the Docker image if you use it), you can activate it as follows: You can define simple queries on the configuration types and components endpoints. These two endpoints support different parameters. Queries on the configurationtype/index endpoint supports the following parameters: type id name metadata of the first configuration property as parameters. Queries on the component/index endpoint supports the following parameters: plugin name id familyId metadata of the first configuration property as parameters. In both cases, you can combine several conditions using OR and AND operators. If you combine more than two conditions, note that they are evaluated in the order they are written. Each supported parameter in a condition can be "equal to" (=) or "not equal to" (!=) a defined value (case-sensitive). For example: In this example, the query gets components that have a dataset and belong to the jdbc-component plugin, or components that are named input. The component-form library provides a way to build a component REST API facade that is compatible with React form library. for example: the Client can be created using ClientFactory.createDefault(System.getProperty("app.components.base", "http://localhost:8080/api/v1")) and the service can be a simple new UiSpecService<>(). The factory uses JAX-RS if the API is available (assuming a JSON-B provider is registered). Otherwise, it tries to use Spring. The conversion from the component model (REST API) to the uiSpec model is done through UiSpecService. It is based on the object model which is mapped to a UI model. Having a flat model in the component REST API allows to customize layers easily. You can completely control the available components, tune the rendering by switching the uiSchema, and add or remove parts of the form. You can also add custom actions and buttons for specific needs of the application. The /migrate endpoint was not shown in the previous snippet but if you need it, add it as well. This Maven dependency provides the UISpec model classes. You can use the Ui API (with or without the builders) to create UiSpec representations. For Example: The model uses the JSON-B API to define the binding. Make sure to have an implementation in your classpath. To do that, add the following dependencies: The following module enables you to define through annotations a uispec on your own models: this can’t be used in components and is only intended for web applications. org.talend.sdk.component.form.uispec.mapper.api.service.UiSpecMapper enables to create a Ui instance from a custom type annotated with org.talend.sdk.component.form.uispec.mapper.api.model.View and org.talend.sdk.component.form.uispec.mapper.api.model.View.Schema. UiSpecMapper returns a Supplier and not directly an Ui because the ui-schema is re-evaluated when `get()̀ is called. This enables to update the title maps for example. Here is an example: This API maps directly the UiSpec model (json schema and ui schema of Talend UIForm). The default implementation of the mapper is available at org.talend.sdk.component.form.uispec.mapper.impl.UiSpecMapperImpl. Here is an example: The getTitleMapProviders() method will generally lookup a set of TitleMapProvider instances in your IoC context. This API is used to fill the titleMap of the form when a reference identifier is set on the @Schema annotation. component-kit.js is no more available (previous versions stay on NPM) and is replaced by @talend/react-containers. The previous import can be replaced by import kit from '@talend/react-containers/lib/ComponentForm/kit';. Default JavaScript integration goes through the Talend UI Forms library and its Containers wrapper. Documentation is now available on the previous link. The logging uses Log4j2. You can specify a custom configuration by using the -Dlog4j.configurationFile system property or by adding a log4j2.xml file to the classpath. Here are some common configurations: Console logging: Output messages look like: JSON logging: Output messages look like: Rolling file appender: More details are available in the RollingFileAppender documentation. You can compose previous layout (message format) and appenders (where logs are written). The server image is deployed on Docker. Its version is suffixed with a timestamp to ensure images are not overridden and can break your usage. You can check the available version on Docker hub. You can run the docker image by executing this command : You can set the env variable _JAVA_OPTIONS to customize the server, by default it is installed in /opt/talend/component-kit. The maven repository is the default one of the machine, you can change it setting the system property talend.component.server.maven.repository=/path/to/your/m2. If you want to deploy some components you can configure which ones in _JAVA_OPTIONS (see server doc online) and redirect your local m2: The component server docker image comes with two log4j2 profiles: TEXT (default) and JSON. The logging profile can be changed by setting the environment variable LOGGING_LAYOUT to JSON. Note that Component Server adds to these default Talend profiles the KAFKA profile. With this profile, all logs are sent to Kafka. You can check the exact configuration in the component-runtime/images/component-server-image/src/main/resources folder. The console logging is on at INFO level by default. You can customize it by setting the CONSOLE_LOG_LEVEL environment variable to DEBUG, INFO, WARN or to any other log level supported by log4j2. Run docker image with console logging: The JSON profile does the following: Logs on the console using the CONSOLE_LOG_LEVEL configuration as the default profile. It uses the formatting shown below. If the TRACING_KAFKA_URL environment variable is set, it logs the opentracing data on the defined Kafka using the topic TRACING_KAFKA_TOPIC. This level can be customized by setting the KAFKA_LOG_LEVEL environment variable (INFO by default). Events are logged in the following format: This profile is very close to the JSON profile and also adds the LOG_KAFKA_TOPIC and LOG_KAFKA_URL configuration. The difference is that it logs the default logs on Kafka in addition to the tracing logs. The component server uses Geronimo OpenTracing to monitor request. The tracing can be activated by setting the TRACING_ON environment variable to true. The tracing rate is configurable by setting the TRACING_SAMPLING_RATE environment variable. It accepts 0 (none) and 1 (all, default) as values to ensure the consistency of the reporting. You can find all the details on the configuration in org.talend.sdk.component.server.configuration.OpenTracingConfigSource. Run docker image with tracing on: By default, Geronimo OpenTracing will log the spans in a Zipking format so you can use the Kafka profile as explained before to wire it over any OpenTracing backend. You can register component server images in Docker using these instructions in the corresponding image directory: Docker Compose allows you to deploy the server with components, by mounting the component volume into the server image. docker-compose.yml example: If you want to mount it from another image, you can use this compose configuration: To run one of the previous compose examples, you can use docker-compose -f docker-compose.yml up. Only use the configuration related to port 5005 (in ports and the -agentlib option in _JAVA_OPTIONS) to debug the server on port 5005. Don’t set it in production. You can mount a volume in /opt/talend/component-kit/custom/ and the jars in that folder which will be deployed with the server. Since the server relies on CDI (Apache OpenWebBeans) you can use that technology to enrich it, including JAX-RS endpoints, interceptors etc…or just libraries needing to be in the JVM.

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.
