内存存储的最佳实践

-- 初始化内存存储服务
local MemoryStoreService = game:GetService("MemoryStoreService")

-- 创建您的排序映射桶
local sm1 = MemoryStoreService:GetSortedMap("sm1")
local sm2 = MemoryStoreService:GetSortedMap("sm2")
local sm3 = MemoryStoreService:GetSortedMap("sm3")
local sm4 = MemoryStoreService:GetSortedMap("sm4")
local sortedMaps = { sm1, sm2, sm3, sm4 }

-- 辅助函数从项目键检索正确的桶
local function getSortedMapBucket(userId)
	local bucketIndex = (userId % #sortedMaps) + 1
	return sortedMaps[bucketIndex]
end

-- 用默认值 0 初始化玩家
for _, player in game:GetService("Players"):GetPlayers() do
	local userId = player.User.Id
	local bucket = getSortedMapBucket(userId)
	bucket:SetAsync(tostring(userId), 0, 600)
end

-- 检索玩家的值
local player = game:GetService("Players"):GetPlayers()[1]
local userId = player.User.Id
local bucket = getSortedMapBucket(userId)
local playerScore = bucket:GetAsync(tostring(userId))
print(playerScore)

-- 初始化内存存储服务
local MemoryStoreService = game:GetService("MemoryStoreService")

-- 创建您的队列
local q1 = MemoryStoreService:GetQueue("q1")
local q2 = MemoryStoreService:GetQueue("q2")
local q3 = MemoryStoreService:GetQueue("q3")
local q4 = MemoryStoreService:GetQueue("q4")

-- 将队列放入数组中
local queueArr = { q1, q2, q3, q4 }

-- 创建两个指针，表示读取和添加队列的索引
local readIndex = 1
local addIndex = 1

-- 创建一个本地函数，适当地更新索引
local function rotateIndex(index, n)
	return (index + n - 1) % 4 + 1
end

-- 创建一个本地函数，从队列中读取 n 个项目
local function readFromQueue(count, allOrNothing, waitTimeout)
	local endIndex = count % 4
	local countPerQueue = count // 4
	local items = {}
	local ids = {}

	-- 遍历每个队列
	for i = 1, 4, 1 do
		-- 确定此队列是否将读取额外的项目
		local diff = i - readIndex
		if diff < 0 then
			diff += 4
		end

		local queue = queueArr[i]

		-- 从每个队列读取项目
		-- 如果符合额外读取标准，则 +1 项
		if diff < endIndex then
			items[i], ids[i] = queue:ReadAsync(countPerQueue + 1, allOrNothing, waitTimeout)
		else
			items[i], ids[i] = queue:ReadAsync(countPerQueue, allOrNothing, waitTimeout)
		end
	end

	readIndex = rotateIndex(readIndex, count)

	return items, ids
end

-- 创建一个本地函数，从队列中移除 n 个项目
local function removeFromQueue(ids)
	for i = 1, 4, 1 do
		local queue = queueArr[i]
		queue:RemoveAsync(ids[i])
	end
end

-- 创建一个本地函数，将项目添加到队列
local function addToQueue(itemKey, expiration, priority)
	local queue = queueArr[addIndex]
	queue:AddAsync(itemKey, expiration, priority)
	addIndex = rotateIndex(addIndex, 1)
end

-- 编写一些代码！

for _, player in game:GetService("Players"):GetPlayers() do
	addToQueue(player.User.Id, 600, 0)
end

local players, ids = readFromQueue(20, true, -1)
removeFromQueue(ids)
