I have put together some LB extensions. One of which updates a LoadDataChange changeLog with various values - eg replaces hard coded FK values in the underlying CSV with key discovery logic.
I then rewrite the changeLog with a revised CSV path (to point to the new CSV file) I also change some of the column types to COMPUTED.
Unfortunately, none of the columns are now written out. The new & unchanged cols are present in the changeLog objects, they are just not written out.
Perhaps you can have a look at this (as well as reinstating the commented out generation code) In the meantime I’m afraid I’m going back to v2…
