I develop a flight that reads all the lines of several files contained in a folder. But I have to know what was the last file and the last line read to be able to resume them if necessary.
I thought of putting it in the database, but thinking that I would have +10 million lines, it would not be nice to update all the time. I therefore had the idea of inserting it into my configuration file.
However, given this approach, these values should be updated, the question is:
Looking semantically, is it wrong to use this approach? And how would I update the value of this key directly in web.config or app.config?
