/**
|
||
* 游戏区服动态数据库连接工具
|

*
|
||
* 游戏每个区服对应独立的数据库 mir_actor_s{serverId}
|
||
* 该模块根据 serverId 动态创建连接池（带缓存，同一区服复用连接）
|
||
*
|
||
* 使用示例：
|
||
* import getGameDB from '../mysql/gameDB.js'
|
||
* const db = getGameDB(1)
|
||
* const [rows] = await db.query('SELECT ...')
|
||
*/

|
||
import config from '../config/index.js'
|
||
import * as log4js from '../log4js.js'
|
||
|
||
// 连接池缓存，避免对同一区服重复创建
|
||
const poolCache = new Map()
|
||
|
||
/**
|
||
* 获取指定区服的 MySQL 连接池（Promise 包装）
|
||
* @param {number} serverId 区服 ID
|
||
* @returns {import('mysql2/promise').Pool}
