I'm curious because I don't want to pay however much it costs to host a server but I also want a good way of handling a global marketplace. Also would roblox's servers be able to handle for example 50k concurrent with a global marketplace in their system.
#What's the most optimized way to creator a global marketplace other than httpservice.

Use a datastore
And keep doing updateasync
But don't cache the data
Always use the value passed into the update function
In order to reduce calls you can batch operations into 1 call
opaque fjord
is that it?
brave flame
Yes
brave flame
I'm not sure what players have to do with it
opaque fjord
i dont know if roblox datastores can handle it
thats one of my concerns
bc i looked up on the devforum
and it said it could overload
and no register data
brave flame
What about it are you worried it can't handle
opaque fjord
not*
just like transfering the data to everyone across all servers
im worried it might not register
brave flame
What are you transferring to everyone
Won't you just be loading the datastore once per server and sending that value to everyone
opaque fjord
like for example i decide to sell a gun for 100 coins and i put it on the global marketplace and then i want someone to be able to purchase it in a different server and recieve it in their inv for example
opaque fjord
Won't you just be loading the datastore once per server and sending that value t...
its gonna update as people put in items to it
brave flame
So each player can update a data store 10 times per minute
And the server can update a data store 60 times per minute
brave flame
But
brave flame
You should not expect the shop to be real time
What you should do is
Make the server update every 10 seconds
opaque fjord
You should not expect the shop to be real time
yeah I would expect like a delay
opaque fjord
Make the server update every 10 seconds
would that cause performance or server issues?
sorry if im asking dumb questions
its 3 am
💀
brave flame
Would updating every 10 seconds be worse then updating as soon as a player adds a item to the datastore
Depends how often players are interacting with it
opaque fjord
definitely not im just asking this if I were to update like every 30 seconds for example and make it reset each item in 24 hours and remove it off the market, and have like a 10 minute cooldown on uploading items to the market would it work fine?
brave flame
You could even update once every second and it would be fine
opaque fjord
oh alr
opaque fjord
And keep doing updateasync
so this would work and I wouldnt need httpservice correct?
brave flame
But the main problem is if 2 servers try to update the data store at the same time the update function can run multiple times
opaque fjord
what would you do against that
brave flame
Update every 10 seconds instead of 1 second
opaque fjord
ok
brave flame
You could have local items and global items
Then every 10 seconds move local items into the global items
opaque fjord
lastly should I dedicate a whole datastore on like managing the marketplace items?
opaque fjord
Then every 10 seconds move local items into the global items
ok
brave flame
When you sell a item you would need to do a updateasync to remove the item
And you can't give the item to the player untill then
opaque fjord
ok
brave flame
an even better way is to
Not just blindly loop
But have like a debounce
So if an update has not happened in the last 10 seconds then instantly allow the action
brave flame
But if a second player comes along then have then wait until the 10 second debouce has ended but you can still take the item from there hands and let it wait in a queue
opaque fjord
can u keep this forum open so I can reference it
