Request was throttled. Try sending fewer requests. Help?

When I buy an item in game, I check the dev console to see if the datastore is saving it, and it says this:

"Request was throttled. Try sending fewer requests."

I was reading something up and it said about adding a 6 second "cooldown" to the datastore, but I'm unsure on how to do that.

Here is the datastore script:

local DataStore = game:GetService("DataStoreService")
local DS1 = DataStore:GetDataStore("LordBlueSkyData")

game.Players.PlayerAdded:Connect(function(player)
	local stats = Instance.new("Folder", player)
    stats.Name = "leaderstats"

	local Coins = Instance.new("IntValue", stats)
	Coins.Name = "Coins"
	
	Coins.Value = DS1:GetAsync(player.userId) or 0
	DS1:SetAsync(player.userId, Coins.Value)
	
	Coins.Changed:Connect(function()
		print("Saving Data...")
		DS1:SetAsync(player.userId, Coins.Value)
	end)
	
end)

game.Players.PlayerRemoving:Connect(function(player)
	DS1:SetAsync(player.userId, player.leaderstats.Coins.Value)
end)

Nevermind, it works.

I thought it was saving items, but it was actually saving the money which I tested and it works.

Sorry about this

You got that because you were trying to save a key before it was done it's previous save. To eliminate that, instead of saving the value every time Coins is changed, you could save Coins in a local place that keeps track of it without saving every time it's changed. Then save Coins every 3-5 or so minutes, as well as when the player leaves / when the game closes.
