What are all the ways to store data on a plugin? I see most examples using the config file but I was thinking of directly modifying the schema of the user to add custom fields. Is this possible via a plugin & if not, what is the best alternative way to do it?
I also see KVSet, can someone explain how that works? Is it scalable to use it as a way to add fields to the user model, and does the data get deleted on plugin uninstall / server restart - where is it stored?
