Shiny as query frontend
My project is to create a data query system using R and Shiny starting from a MySQL database. My intention is to install a server with ShinyApp (Installing shiny server on Debian VM) in which to create a copy of the data in .rds format (files larger than 100 MB) in order not to burden the MySQL server, and use Shiny as a front-end that "writes" extraction queries using buttons and reactive selections (radio buttons, sliders, checkboxes, etc.).
Each user would then connect to the app choosing their own parameters, would read .rds files and download the records in .csv / .xlsx format.
Given that the data takes up a lot of space, I think the best solution is to put them in a folder outside the app and not include them directly inside (are there any limits in the size of the app if it is loaded on a local server?).
I do not know if I was clear enough to illustrate what I have in mind and what the function of the app should be, but do you think it's possible because of how Shiny is structured?

Your questions is very broad. Actually, I can't understand what are you asking. What's your specific question? are there any limits in the size of the app if it is loaded on a local server?

Why are you worried about the "burden" on MySQL --- this is just the kind of thing it is designed for. When you say local server. ... are you saying that users will launch their own shiny app locally (on their own computers)?

I prefer to use a local server (a PC connected to the network on which to install a shiny server) instead of the company's MySQL server because we only have access to this app in 4/5 people via a browser. The options would be 2: copy the data to an "App / Data" folder or copy it outside the app. stackoverflow.com/questions/18037737/…
