A Question In Regards to Having a Central Vault and System Resources

Things I have tried

What I’m trying to do

i am trying to make a huge list of stuff in books and tag them to categorize them, the problem is that dataview only work with notes as atomic unites not heading. it is a easy problem to fix by making a note for every entry. but the issue is that i think i am going to grow number of notes in my vault very quickly just because of a lot of empty notes with some tags and metadata in them, and i am not sure how the computer and update is going to handle it. i mean it is already very slow to copy it. i appreciate if someone can guide me in this regards. i think that should be a common issue for many. i want a central big vault to link to it easily and connect the dots. so separating related vaults is not a option
