Error handling at design
This section explains how to integrate error handling in the Job design.
Apart from the built-in components and link triggers provided by Talend, you can handle errors very effectively by integrating the logic in the Job design itself using processing components such as tMap.
In this example, tMap is used to determine the data flow. All the error records that need reprocessing are notified to business users via email. The rejects are written to a file, probably for reprocessing, and the delta records are written to the table.
