The code above shows how I handle Developer Product purchases and when a player leaves the game.
However, there is a warning that said:
DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests. Key = playerName
This happens if a player purchases Developer Products too quickly.
How would I send fewer requests so that this warning would go away?
This doesn’t answer your initial question, but you should use the player’s ID as a key. Using their name is a really really bad idea as users can change their username easily.
You should place the Robux Donated things in a queue that only uses DataStores once every x minutes. Once every 1 minute may be enough. The reason behind this is to prevent multiple DataStore usage all at once when players purchase developer products a lot of times within a short period of time.
Example code:
local playerQueue = {}
local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService'Players'
local DataStoreService = game:GetService("DataStoreService")
local RobuxDonatedDataStore = DataStoreService:GetDataStore("RobuxDonated", "RobuxDonatedScope")
coroutine.wrap(function()
while true do
wait(60)
for player, addedRobux in pairs(playerQueue) do
local success, newData = pcall(function() --use pcall for datastores!
return RobuxDonatedDataStore:SetAsync(player.Name, addedRobux) --PSA: Don't use Player Names in storing data! Use IDs instead
end)
if not success then
--do error handling here for when the data fails to save!
else
print('Saved!')
end
playerQueue[player] = nil
end
end

PS: This is just an example code. I haven’t tested it but doing that should fix the issue you’re experiencing
dont make the same mistake they did
