How would i make this Filtering Enabled?

Im having trouble making this Datastoring script Filtering Enabled. Any idea on what to add to make it do so?

local DSService = game:GetService('DataStoreService'):GetDataStore('DBSRData')
game.Players.PlayerAdded:connect(function(p)
    wait(2.5)
    -- Define variables
    local stats = game.ServerStorage.Data:Clone()
    stats.Parent = p
    local uniquekey = 'id-'..p.userId
    local names = {}

    for i, v in pairs(p.Data:GetChildren()) do
        table.insert(names, v.Name)
    end

    -- GetAsync
    local GetSaved = DSService:GetAsync(uniquekey)
    if GetSaved then
        for i, v in pairs(p.Data:GetChildren()) do
            v.Value = GetSaved[i]
        end

        for i=1, #GetSaved do
                --print(i .. ": " .. names[i] .. " = " .. tostring(GetSaved[i]))
        end
    else
        local NumbersForSaving = {}
            for i, v in pairs(p.Data:GetChildren()) do
                table.insert(NumbersForSaving, v.Value)
            end
        DSService:SetAsync(uniquekey, NumbersForSaving)
    end
end)

game.Players.PlayerRemoving:connect(function(p)
    local uniquekey = 'id-'..p.userId
    local Savetable = {}
        for i, v in pairs(p.Data:GetChildren()) do
            table.insert(Savetable, v.Value)
        end

    DSService:SetAsync(uniquekey, Savetable)            
end)
