To debug a job using Trace Debug mode and pause the execution when it encounters any records for

customers residing in the state of California, you need to right-click on the trace on the output of the

input component and select Show Breakpoint Setup option. 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. A trace is a link that shows the data flow between components in your job

design workspace.

The Show Breakpoint Setup option allows you to set a breakpoint on a trace based on a condition or

an expression. A breakpoint is a point where the execution of your job pauses and waits for your

action. You can use breakpoints to inspect your data or debug your logic at specific points of your job

execution. You can access this option by right-clicking on a trace on your job design workspace and

selecting Show Breakpoint Setup. This will open a dialog box where you can enter a condition or an

expression for your breakpoint.

For example, if you want to pause your job execution when it encounters any records for customers

residing in the state of California, you can enter this condition for your breakpoint:

row1.state == “CA”

This will make your job stop at the trace where this condition is met and show you the values of each

column for that row.

You do not need to add a breakpoint in Advanced settings tab of Run view, open Debug Run tab of

Run view and click Trace Debug button, or right-click on trace on output of input component and

select Add Breakpoint option. These options are not used to set breakpoints based on conditions or

expressions. The Advanced settings tab of Run view is used to configure advanced settings for your

job execution, such as JVM arguments, statistics parameters, implicit context load parameters, etc.

The Debug Run tab of Run view is used to access Trace Debug mode, but not to set breakpoints. The

Add Breakpoint option is used to add a simple breakpoint on a trace without any condition or

expression. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,
