How can I use datastore more efficiently?

local level = game:GetService("DataStoreService"):GetDataStore("Level")
local xp = game:GetService("DataStoreService"):GetDataStore("EXP")
local totalxp= game:GetService("DataStoreService"):GetDataStore("totalxp")
local gold = game:GetService("DataStoreService"):GetDataStore("gold")
local win= game:GetService("DataStoreService"):GetDataStore("Wins")
local death= game:GetService("DataStoreService"):GetDataStore("Deaths")

function save(dataname, playerid, value)
	game:GetService("DataStoreService"):GetDataStore(dataname):SetAsync(playerid, value)
end

I've been saving multiple stats like gold, wins, exp like this, and I used to make it so whenever exp changed it would save all the values, and sometimes it was too much for the server to handle.

save("Level",player.UserId,player.leaderstats.Level.Value)
save("EXP",player.UserId,player.EXP.Value)
save("totalxp",player.UserId,player.xpremaining.Value)
save("gold",player.UserId,player.Coins.Value)
save("Wins",player.UserId,player.Wins.Value)
save("Deaths",player.UserId,player.Deaths.Value)

Is there a way to prevent saving issues in the future if it can't all be handled to save all this when the xp is changed or when the player leaves?

You don't need to utilize a seperate datastore for each value. You can simply create a table with the values you want to save and save the table into the datastore.
