somewhere only in one place there will be main index with at least references to locations where to find others. at the top somewhere there is always just a flat list. this is a multi-dimensional problem. i really want to know real life scenario someone arguing for or against this. really interested to see what side people pick and where they draw the line of what it means to be multi-tenant. personally, i will never again write multi-tenant code ever again in my life. the implementation i've modeled for myself because i understood that immediate backup and restore is more important than fancy multi-tenancy.
