Lakehouse - Delta table columns not updating
Hi all, I am using a Python Notebook that's being triggered by a data factory to update Delta tables each night. In short, the process is as follows: 1. A data factory orchestrates all processes...
That's a pity. Is this a known problem that will be fixed in the future, or is it how the Lakehouse is supposed to work?
I switched to the ALTER statements in my notebook as using mergeSchema did not work at all. I tried to use this in the first place. Source DF contained 2 new columns. I wrote it into the target delta table, and then after querying the target again, the columns were not there at all.
