Can you please help out with this
There is 'dynamic schema' feature in talend subscription solution which allows you to design schema with an unknown column structure (unknown name and number of columns).
Here is a related troubleshooting-Development document about https://community.talend.com/t5/Troubleshooting-Development/How-to-process-changing-data-structure/t....
Hope it will help.
