Saving data effieciently

Help and Feedback Scripting Support
#1

Good morning, Roblox Developer Forum! I’m currently attempting to make an election voting poll (for a fiction game I am an administrator in), and I am having trouble thinking of an efficient method to save data.

Right now, this is a step-to-step system of how I want my code to work:

  • Player votes on a nominee via. a TextButton
  • LocalScript recognizes MouseButton1Click, fires a remote
  • Script recognizing the FireServer, retrieves the data of how many votes the nominee selected has, and adds 1 to the data (will always be a number)
  • Script then saves the data

I originally chose to use DataStoreService, however, someone in the server mentioned that when the server receives a high amount of requests at once, ROBLOX will deny some of them. This being said, does anyone have any good ideas to efficiently save data?

Thanks! :ok_hand:

You can cache the data instead of writing to the datastore everytime. When the game loads, you can load all the nominees into a dictionary with the value of 0. Then, whenever a user votes, add 1 vote to the nominee’s value. You could then periodically save the data, adding the value from inside the dictionary into the datastore and using :UpdateAsync to update the data within the datastore, you should then set the nominee’s dictionary back to 0. You should also use :BindToClose() for when the game is closing, and save the data into the datastore there.

I don’t see a point in saving the data periodically, the person can only vote once, and when they voted, they will be kicked. What is the difference between this and my failed strategy?

#4

If you don’t need to vote on all servers, you can use variables.

#5

Do you mean saving the nominee’s data all through 1 variable? I am trying to save this data to some form of database (DataStoreService, even Mongoose if I can’t find any other viable option).

#6

If it’s 1 player servers, there shouldn’t be a problem with saving it when they fire the remote event.

#7

Like this:

local Vote = {Apple=0,Orange=0,Banana=0}

VoteEvent.OnServerEvent:Connect(function(player,voteto)
  Vote[voteto] = Vote[voteto] + 1
end)
#8

But saving to a datastore is global, through the whole game and not just the server. I think ROBLOX has a cooldown system on this, not to say it isn’t lenient, but still.

#9

Thanks for your response, however I am trying to save it globally, so I can review the votes when everyone is finished voting.

Or you can just use MessagingService to give the updated data to every server, then use :BindToClose() and save the data, that shouldn’t throttle.

#11

I’m not familiar with MessagingService

#12

There is a Tutorial for Messaging Service.

I checked this page, it says DataStoreService doesn’t necessarily decline the requests, however just throttles the server, delaying the time for it to finally upload.

#14

After doing some digging around, I have decided to just use DataStoreService. I believe ROBLOX doesn’t throttle many requests from different servers, so I think it’ll be okay.

Thank you for your support.

I think the DataStore Service only saved it once every 6 seconds in one server…
