I need to be able to store a max of 500 userids or close to 5002 characters into DataStore for all servers to access and read. If anyone has a handy function that stores userids and reads it when it updates. I would like to see.
I looked on the wiki and roblox limits DataStore string saving to 16^2 characters.
Check again; it's actually 2^16 characters, not 16^2. Big difference! A JSON table of 500 userIds won't exceed that. You'll be fine!
