Trace Debug mode is a feature that allows you to trace each row processed by your job components and see the values of each column in each row. You can access this mode by opening the Debug Run tab of the Run view and clicking on Trace Debug button.

The capabilities that Trace Debug mode provides are:

Breaking when an input column fulfills a condition. You can set breakpoints on traces based on a condition or an expression that involves input data columns. For example, you can set a breakpoint to pause your job when a customer name contains a certain string or when a product price exceeds a certain value. To set a breakpoint based on a condition, you need to right-click on a trace on your job design workspace and select Show Breakpoint Setup option. This will open a dialog box where you can enter a condition or an expression for your breakpoint.

Advancing one row at a time. You can advance the execution of your job one row at a time by using the Step Over button in the toolbar of the Run view. This will allow you to see how each row is processed by your job components and how it affects the output data.

The capabilities that Trace Debug mode does not provide are:

Filtering which data is propagated by a flow. You cannot filter which data is propagated by a flow in Trace Debug mode. A flow is a link that shows the data transfer between components in your job design workspace. In Trace Debug mode, you can see the data flow on each trace and inspect the values of each column for each row processed by your job. However, you cannot change which rows are propagated by a flow based on a condition or an expression.

Advancing one column at a time. You cannot advance the execution of your job one column at a time in Trace Debug mode. You can only advance the execution of your job one row at a time by using the Step Over button in the toolbar of the Run view. This will allow you to see how each row is processed by your job components and how it affects the output data. However, you cannot see how each column is processed by your job components and how it affects the output data.

Breaking on a selected line of code. You cannot break on a selected line of code in Trace Debug mode. You can only break on a trace based on a condition or an expression that involves input data columns. To break on a selected line of code, you need to use Java Debug mode. Java Debug mode allows you to debug your job code in Java or Perl and see the values of each variable or expression in your code. You can access this mode by switching to the Java perspective and clicking on the Debug button in the toolbar of the Code view.

To create a job consisting of two subjobs, A and B, and add a Joblet C with the intention of running it between A and B, you need to do the following steps:

Design subjob A by adding components and links to it in the Designer workspace.

Add a Start component to mark the beginning of subjob B and link it to subjob A using an OnSubjobOk trigger.

Design subjob B by adding components and links to it after the Start component in the Designer workspace.

Add a tJobletTriggerInput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.

Add a tJobletTriggerOutput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.

Drag your Joblet C from the Repository tree view to the Designer workspace between subjob A and subjob B.

Link your Joblet C to subjob A using an OnComponentOk trigger from the last component of subjob A to the tJobletTriggerInput component of your Joblet C.

Link your Joblet C to subjob B using an OnComponentOk trigger from the tJobletTriggerOutput component of your Joblet C to the Start component of subjob B.

The minimum requirements to orchestrate this are adding TRIGGER_INPUT and TRIGGER_OUTPUT components into C and linking A, B, and C using OnSubjobOk triggers. These are generic components that allow you to define triggers for your Joblet without depending on specific components. You do not need to add TRIGGER_INPUT and TRIGGER_OUTPUT components into A or B, as these are regular subjobs that can use any type of components or triggers.

In a tMap component, naming an output row correctly helps in managing data flow efficiently. The correct methods are:

A . Click the name of the table in the Map Editor window and edit it.

Open tMap, locate the output table, and click its name to edit it directly.

B . Assign the name when defining a new output table in the Map Editor window.

When adding a new output table, you can name it immediately in the Map Editor.

D . Assign the name when connecting a new output component.

When you connect an output component to tMap, you can assign a custom row name.

To create an empty Joblet, you need to right-click on the Joblet Designs node in the Repository tree view and select Create Joblet option. This will open a dialog box where you can enter the name and description of your Joblet and select an icon for it. You can then design your Joblet by adding components and links to it in the Designer workspace.

You cannot create an empty Joblet by creating an empty job, then exporting it as a Joblet by right-clicking it in the Repository, creating an empty job and using the file menu to save it as Joblet, or right-clicking a space in the Designer and selecting refactor to Joblet. These methods are not available in Talend Studio and may cause errors or unexpected results. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Joblets - 7.3]

Comprehensive and Detailed Explanation:

In Talend Cloud Data Inventory, when a user creates a dataset using a shared connection, the following applies:

User B has full access to Dataset_1 (Option D):

Once User B creates Dataset_1 using the shared connection, they become the owner of that dataset. Even if User A later revokes access to the connection, User B retains full access to Dataset_1. The dataset's accessibility is independent of the connection's sharing status after its creation.

Why not other options?

Option A: User B's access to Dataset_1 is not limited; they have full ownership and control.

Option B: Revoking the connection does not remove User B's access to datasets they have already created.

Option C: User A's access to Dataset_1 depends on the sharing settings applied by User B; by default, User A does not have access unless granted.
