There are rules on the sequence in which Job Entries are executed.
In this demonstration the Job Entries were placed on the canvas in the following order:
START
Transformation A
Transformation B
Transformation C
Success
The Job will start with Transformation A as this was placed first on the canvas.
Even though Transformation C and Success were placed on the Canvas after Transformation B .. it will be executed before Transformation B as there's a hop from Transformation A.
Once the Transformation A pipeline has been completed with a success then Transformation B will be executed.
RUN the Transformation
Click the Run button in the Canvas Toolbar.
Click on the Job Metrics tab.
as you can see from the Job metrics Transformation A -> Success is executed before Transformation B. Check the dependencies ...
