scoping questions

Hi all,

I am reading: Shiny - Scoping rules for Shiny apps

I have a large data file that I don't want each user to load but I want it to be loaded once. My understanding is that I place the data import outside the server function in app.R and it will be available for all user sessions.

My question is for how long is that stored so that sessions can access it? Can I call a function to see how long data is stored for (I presume in memory)?

If I updated the data then do I need to restart the server?
