Awesome stuff, though I have one quick question.
How would I save data to a player if they aren’t present in the server?
To elaborate I noticed I must pass a player object through to get the player’s data, instead of a traditional UserId int.
DATA_STORE(DATA_KEY,plr):Get(NewPlrDataTable)
-- What I'd like to do
DATA_STORE(DATA_KEY,UserId):Get(NewPlrDataTable)
To reasses, I need to grab and save data to a player that is not in a server. Is there a safe way of doing this with DataStore2?
I do apologize if there’s an obvious answer I missed. Thanks again, ingenious stuff my guy. 
Edit: After dabbling a bit I realized that you can only use a player instance. Was hoping to use this method for a way to ban during run-time on players that are not present in the server using the same Data-Store, but I believe I will have to use alternatives.

DataStore2 doesn’t support this innately because it’s not completely safe, users can be in different servers where the cache won’t recognize the new data and whatnot. DataStore2’s code isn’t very complex, so you can figure out how it works and emulate it.

A wrapper would just use a separate ordered data store and set the values whenever DataStore2 updates.
Could you possibly go more in depth on this?

As in, you’d have to manually make an ordered data store and whenever you save in DataStore2, you’d update that ordered data store too.

Thank you for making the video tutorial! This is great with the addition of the text tutorial in this post.

Alright I am new to DataStore2 and would like to use it in my game, but I’ve been trying to Set/Get a table but it doesnt seem to work. Any Ideas anyone?

You can just use :Get and :Set normally with tables, they’re nothing different. What is giving you trouble?
2 Likes
Yeah, I figured that’s what you meant but I wanted to confirm.
Wouldn’t saving another DataStore every time DS2 updates cause too many requests?
2 Likes
Not whenever it updates, but when it saves (with :AfterSave).

Totally overlooked :AfterSave, thanks! 
Hopefully that was the last question!

i’m probably dumb or something, but how would i look through the data of a player in Datastore Editor (by Crazyman32) with this system?

@Kampfkarren I am having trouble with this. I’m sort of familiar with DataStores, i can do them, however, i am trying to save a lot of values in a table. But i’m not familiar with serializing and deserializing, i’m not sure what they mean either.
I cant find any help anywhere with this. Lets say you have a table with a lot of values stored inside, and its stored into the one data store, how do you go about picking that one value and changing it in the store itself. I understand very well if it was just one value in the store, but i cant seem to wrap my head around saving tables, and many many values. Please help!
As an example i used the basic serialized and deserialized example you gave, and am failing at integrating it… because i dont know how in this case 
local SpellDefaultTab = {
["Basic Shield"] = true;
["Orlora"] = true;
["Branda Mirun"] = false;
["Valroc Mirun"] = false;
["Varia"] = false;
["Orlovium"] = false;
["Caecus"] = false;
["Crimbiu"] = false;
["Crimbastu Lackra"] = false;
["Fustama Truvista Livistu"] = false;
["Orlovick"] = false;
["Flithrumar Calivum Brathcavan"] = false;
["Duble Baldadre Hadra"] = false;
["Ible Siezumeum"] = false;
["Blonia Prostagalera"] = false;
["Portalium"] = false;
["Arathalat"] = true;
["Basic Shield Mastery"] = 2;
["Orlora Mastery"] = 2;
["Branda Mirun Mastery"] = 2;
["Valroc Mirun Mastery"] = 2;
["Varia Mastery"] = 2;
["Orlovium Mastery"] = 2;
["Caecus Mastery"] = 2;
["Crimbiu Mastery"] = 2;
["Crimbastu Lackra Mastery"] = 2;
["Fustama Truvista Livistu Mastery"] = 2;
["Orlovick Mastery"] = 2;
["Flithrumar Calivum Brathcavan Mastery"] = 2;
["Duble Baldadre Hadra Mastery"] = 2;
["Ible Siezumeum Mastery"] = 2;
["Blonia Prostagalera Mastery"] = 2;
["Portalium Mastery"] = 2;
["Arathalat Mastery"] = 2;
}
Players.PlayerAdded:Connect(function(Player)
local SpellsStore = DataStore2("SpellsStorage", Player)
local SpellData = Instance.new("Folder")
SpellData.Name = "SpellData"
SpellData.Parent = Player
for statname, statvalue in pairs(SpellDefaultTab) do
if type(statvalue) == 'number' then
local intvalue = Instance.new("NumberValue")
intvalue.Name = statname
intvalue.Parent = SpellData
elseif type(statvalue) == 'boolean' then
local boolvalue = Instance.new("BoolValue")
boolvalue.Name = statname
boolvalue.Parent = SpellData
elseif type(statvalue) == 'string' then
local stringvalue = Instance.new("StringValue")
stringvalue.Name = statname
stringvalue.Parent = SpellData
end
end
SpellsStore:BeforeInitialGet(function(Spells)
local deserialized = {}
for _,SpellId in pairs(Spells) do
for key,value in pairs(SpellDefaultTab) do
if value == SpellId then
table.insert(deserialized, key)
end
end
end
return deserialized
end)
SpellsStore:BeforeSave(function(Spells)
local serialized = {}
for _,SpellVal in pairs(Spells) do
table.insert(serialized, SpellDefaultTab[SpellVal])
end
return serialized
end)

How do i set a value that is inside a table thats stored? Something like this?
local SpellsStore = DataStore2("SpellsStorage", Player)
for key,value in pairs(SpellsStore:Get({})) do
if key == "Orlovium" then
SpellsStore:Set(true)
end
end

There’s nothing special about tables for DataStore2. How would you set the table normally? Just do that then :Set with the new table.

Make sure this works without [de]serialization, if it does then that means it’s an issue with your BeforeInitialGet/BeforeSave implementations.

It’s a hassle, but it’s possible. From what I remember, this is how you do it.
- Figure out what the data store name is going to be.
A DataStore2 name consists of two parts: KEY/USER_ID. The key is either the master key if you’re using combined data stores, the normal key otherwise. Let’s say our combined data store key is DATA and we’re looking for the data of ROBLOX. We would search: DATA/1.
- Toggle OrderedDataStores and Query.
- Write down the value of the most recent result.
- Turn off OrderedDataStores, and search with the key being what you just wrote down.

oh wait real quick, any specific way of incrementing a value in the table within the datastore?

No, don’t think of tables as anything different in terms of DataStore2.
