How should I go about saving "Roles" (DataStores)

Hi! I’m trying to store “roles” inside of Roblox, like Discord. Roles will be given in-game, created in-game, and edited in-game. I need to be able to:

  • see all the roles a player has,
  • the info of a role (name, description, etc),
  • see every single role.

i’ve looked into :ListKeysAsync(), but theres no way to get the value inside that key without sending an extra get request. i’ve looked into “chunks”, but it doesn’t feel like a very scalable solution with how my datastore is set up right now.

how my datastore is set up right now:

local PlayerDataStore = {
	[98432423] = { -- A UserId
		Roles = {123} -- A bunch of role Ids
	}
}

local SystemDataStore = {
	Roles = {
		[123] = { -- The role ID
			Name = "Name",
			Description = "Description",
			-- Some other useful data...
			Players = {
				948294832,
				943254354363,
				432849032432432, -- UserIds
			}
		}
		-- A bunch of other roles
	}
}

-- Heres the problem

local function makeChanges(roleId, newRoleInfo)
	local data = SystemDataStore.Roles -- Get every roles data using a :GetAsync() request...
	
	data[roleId] = newRoleInfo
	
	-- Do some checks so were only updating the players that had their roles changed...
	
	for index, userId in newRoleInfo.Players do
		local playerData = PlayerDataStore[userId] -- run a :UpdateAsync() call and give/remove the role from their "Roles" list
	end
end

This works great, but it reaches datastore limits very quickly. especially if a lot of players were given/revoked a role.

Limitations

  • Must be able to fetch ALL roles, and some “basic” data a long with every role (name & description).
  • Should be able to see every player that has that role.
  • Should be able to see every role a player has.
  • Should be able to take away or remove a group of players role.
  • Should be fairly scalable
  • Should not spam :GetAsync(), :SetAsync(), etc…

Is this only possible with external datastores at the moment?

You should only check the roles of a player once (when they join), why are you saving the info? You don’t need to store the players of an info if you are already storing them elsewhere

Sorry, I should’ve been a bit more descriptive; these roles need to be persistent across all servers. So if someone removes a players role on server 2, a player in server 1 will be able to see that change. These roles will also be used for checking if a player has permissions to ban, kick, mute, etc.

You could use buffers or table packing, while removing unnecessary fields
