Data-Integration-Developer Exam Syllabus & Core Topics

Use this topic map to guide your study for Talend Data-Integration-Developer (Talend Data Integration Certified Developer Exam) within the Talend Data Integration Certified Developer path.

  • Getting started with data integration: Understand Talend Studio interface, project setup, and basic job creation. You must be able to navigate the designer, configure repositories, and launch your first data flow.
  • Joining and filtering data: Master join operations (inner, left, right, full outer) and filter logic to combine and refine datasets. Apply these techniques to merge customer and transaction tables or exclude invalid records.
  • Error handling: Design robust error-handling strategies using reject links, try-catch logic, and conditional flows. Capture failed records and route them to dedicated error tables or logs.
  • Orchestrating Jobs: Chain multiple jobs together using triggers, dependencies, and context passing. Manage job execution order and handle success/failure scenarios in production workflows.
  • Project management: Organize jobs, components, and metadata in logical folders. Version control, document job purpose, and maintain code standards across team projects.
  • Working with files: Read and write CSV, Excel, JSON, XML, and fixed-width files. Handle file encoding, delimiters, and schema validation during data import and export.
  • Using context variables: Define and pass context variables to parameterize jobs. Use contexts for environment-specific values (database credentials, file paths, date ranges) without hard-coding.
  • Working with databases: Connect to relational databases, execute queries, and perform bulk inserts or updates. Optimize database operations using batch modes and connection pooling.
  • Deploying Jobs: Package jobs for production, configure runtime environments, and manage job schedules. Deploy to Talend Runtime or standalone Java executables.
  • Debugging: Use logs, breakpoints, and row counts to troubleshoot data flows. Identify bottlenecks, validate row counts at each stage, and verify data quality in intermediate steps.

Question Formats & What They Test

The Talend Data Integration Certified Developer Exam combines knowledge-based and scenario-driven questions to assess both conceptual understanding and practical decision-making. Questions progress in difficulty and reflect real-world integration challenges.

  • Multiple choice: Test core definitions, component behavior, and Talend terminology. Example: "Which component is used to split a single input row into multiple output rows?"
  • Scenario-based items: Present a real data integration problem and ask you to choose the best design approach. Example: "A customer file arrives daily with duplicate records. Which combination of components would you use to deduplicate before loading to the warehouse?"
  • Configuration reasoning: Evaluate job design decisions, such as choosing the right join type, error-handling strategy, or deployment method for a given business requirement.
  • Process flow analysis: Interpret job diagrams and predict outcomes based on component settings and data flow logic.

Preparation Guidance

Build a structured study plan by mapping exam topics to weekly milestones and combining hands-on practice with review cycles. Allocate more time to topics like orchestration and error handling, which often carry higher weight. Consistent, focused practice over two to three weeks yields better results than cramming.

  • Map Getting started with data integration, Joining and filtering data, Error handling, Orchestrating Jobs, Project management, Working with files, Using context variables, Working with databases, Deploying Jobs, and Debugging to weekly goals. Track progress with a checklist.
  • Practice question sets; review explanations to fix weak areas. Understand not just the correct answer, but why alternatives are incorrect.
  • Link features and concepts across planning, execution, and reporting workflows. For example, understand how context variables flow through orchestrated jobs and how error handling integrates with logging and monitoring.
  • Do a timed mini-mock (30-45 minutes) to build pacing and reduce test anxiety. Simulate exam conditions and review timing per question type.
  • In the final week, focus on weak topics and re-read component documentation for any features you felt uncertain about.

Frequently Asked Questions

Which topics typically carry the most weight in the Data-Integration-Developer exam?

Error handling, orchestrating jobs, and working with databases tend to appear frequently because they directly impact production reliability and performance. Joining and filtering data also represent core competencies tested across multiple question types. Focus extra study time on these areas while ensuring you have solid foundational knowledge of all topics.

How do the different topics connect in a real data integration project?

A typical project flow starts with Getting started with data integration (project setup), moves through Working with files and databases (data sources), applies Joining and filtering data (transformation logic), incorporates Using context variables (parameterization), adds Error handling (robustness), uses Orchestrating Jobs (workflow management), and concludes with Deploying Jobs and Debugging (production support). Understanding these connections helps you design end-to-end solutions rather than isolated components.

How much hands-on experience do I need, and which labs should I prioritize?

Hands-on practice is essential; aim for at least 10-15 hours building actual jobs in Talend Studio. Prioritize labs covering error handling (reject links and conditional flows), database operations (bulk loads and incremental updates), and job orchestration (chaining jobs with context passing). These labs reinforce concepts that appear frequently on the exam and directly translate to workplace tasks.

What are common mistakes that lead to lost points?

Candidates often overlook error-handling requirements, assume all joins are inner joins by default, or underestimate the importance of context variables for parameterization. Another frequent error is choosing the wrong component for file formats (e.g., using tFileInputDelimited for JSON). Review component capabilities and test your assumptions with sample data before finalizing job designs.

What is an effective review strategy for the final week before the exam?

In the final week, focus on weak topics identified during practice tests rather than re-reading all material. Do a full timed practice test mid-week to gauge readiness, then spend the remaining days reviewing explanations for incorrect answers. On exam day, arrive early, read questions carefully, and flag difficult items to revisit if time permits. Avoid last-minute cramming, which increases anxiety and reduces retention.

Question No. 1

Where can you specify the remote JobServer to execute a Job?

Show Answer Hide Answer
Correct Answer: D

To specify the remote JobServer to execute a job, you need to use the Target Exec tab in the Run view of Talend Studio. The Run view allows you to configure and execute your job from Talend Studio. The Target Exec tab allows you to select whether you want to run your job locally or remotely on a JobServer. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. To run your job on a remote JobServer, you need to select Remote Jobserver option from the drop-down menu and select or add a JobServer connection from the list.

You do not need to use Job settings section of Project Settings window, Extra tab in Job view, or Run/Debug section in Preferences window. These windows are not used to specify remote JobServer execution. The Job settings section of Project Settings window is used to configure general settings for your jobs, such as versioning, statistics, logs, etc. The Extra tab in Job view is used to configure extra features for your job, such as implicit context load, tStatCatcher, tLogCatcher, etc. The Run/Debug section in Preferences window is used to configure run/debug settings for your Talend Studio, such as JVM arguments, execution mode, etc.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Run view - 7.3], [Project Settings - 7.3], [Job view - 7.3], [Preferences - 7.3]


Question No. 2

Which statements ate true about a tWarn component?

Choose 2 answers

Show Answer Hide Answer
Correct Answer: A, C

The tWarn component is used to trigger a warning message that can be caught by the tLogCatcher component for an exhaustive log. The tLogCatcher component is a component that collects the log data generated by the tWarn, tDie, and Java Exception components and passes it on to the output defined. The tWarn component can be used alongside a tLogCatcher component in order for the log data collected to be encapsulated and passed on to the output defined. The tWarn component can also be used independently of the tLogCatcher component, but in that case, the warning message will only be displayed in the console. The tWarn component is not used only in conjunction with the log4j feature, nor only in conjunction with a tLogCatcher component. The log4j feature is a logging framework that allows you to customize the logging level, format, and destination of your log messages. You can enable or disable the log4j feature in Talend Studio by checking or unchecking the Use log4j option in the Preferences menu. The tLogCatcher component can catch log data from other components besides the tWarn component, such as the tDie and Java Exception components.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend,


Question No. 3

You designing a Job that can run in two contexts, Test and Production. You want to run it as a standalone job outside Talend Studio.

How do you accomplish this?

Show Answer Hide Answer
Correct Answer: D

To design a job that can run in two contexts, Test and Production, and run it as a standalone job outside Talend Studio, you need to do the following steps:

Define the context variables and values for each context in the Contexts tab of your job. A context variable is a variable that can store a value that can be changed at runtime or between different contexts. You can use context variables to parameterize the properties or expressions of your job components.

Build the job with the desired context selected in the Build Job window. You can access this option by right-clicking on your job in the Repository tree view and selecting Build Job. This will open a dialog box where you can configure the build settings, such as destination folder, archive name, context, etc. You need to select the context that you want to use for your job execution from the drop-down menu.

Extract the content of the archive file that contains your job executable files and libraries. The archive file also contains two executable files: a batch file (.bat) for Windows platforms and a shell script (.sh) for Linux platforms. You need to run the appropriate file for your platform by double-clicking on it or using a command line tool. This will launch the job and display its output in a console window.

If you need to run the job in a different context, you need to build a separate copy of the job with the other context selected in the Build Job window. You cannot change the context of an already built job without rebuilding it.

You do not need to build the job with the Context scripts option selected in the Build Job window, edit the script according to the context in which you want to run the job, set the desired context as the default, rebuild the job if you need to run it in a different context, or be prompted for the context. These methods are not correct or available in Talend Studio and may cause errors or unexpected results.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Build Job - 7.3], [Contexts - 7.3]


Question No. 4

Which file should you edit to enable SSL for a JobServer?

Show Answer Hide Answer
Correct Answer: A

To enable SSL for a JobServer, you need to edit the conf/TalendJobServer.properties file. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. The conf/TalendJobServer.properties file contains various configuration parameters for your JobServer, such as port number, log level, security options, etc. To enable SSL for your JobServer, you need to set the ssl parameter to true and provide the path and password of your keystore file that contains your SSL certificate.

You do not need to edit conf/TalendServer.properties, conf/server.xml, or jsl_static64.ini files. These files are not related to JobServer configuration or SSL settings. The conf/TalendServer.properties file is used to configure Talend Administration Center settings, such as database connection, LDAP authentication, email notification, etc. The conf/server.xml file is used to configure Tomcat server settings, such as connectors, realms, valves, etc. The jsl_static64.ini file is used to configure Java Service Launcher settings, such as service name, description, startup type, etc.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Configuring Talend JobServer - 7.3], [Configuring Talend Administration Center - 7.3], [Configuring Tomcat - 7.3], [Installing Java Service Launcher - 7.3]


Question No. 5

You have a Job that uses a tFileInputDelimited component to extract data from an input file. You built a spate subjob, called W, to handle the condition when the input file is empty.

Which condition syntax is correct for the Run if connection?

Show Answer Hide Answer
Correct Answer: C

To reference the value of a context variable you defined, you can use the syntax context.variable_name, where variable_name is the name of the context variable. For example, if you have a context variable named path, you can reference its value by using context.path. You do not need to specify the context name (such as test or prod) or use parentheses or brackets around the variable name.Reference:Talend Data Integration --- Software to Connect, Access, and Transform Data | Talend, [Contexts - 7.3]
