状态： - 9 个 sync task（stock_basic / kline_daily / kline_index / kline_5min / moneyflow / industry_sector / sector_features / share_snapshot / market_regime） - 数据源：baostock + mairui + 雪球(pysnowball) + 新浪（4 个） - 项目级约束：永远不用 akshare（已落实） - kline_5min 改用 DB 快照统一全量/增量逻辑 - 零后端 Chrome 扩展 xueqiu_sync（独立项目）

"""同步任务：5 分钟 K 线（mairui）。
|
||
|
||
设计要点：
|
||
1) 启动时**一次 SQL** 拿全表 {stock_code: max(bar_time)} 快照
|
||
2) 内存里给每只股票算 (start, end, windows_needed)
|
||
- DB 没数据 → start = mairui 历史深度起点 (2023-06-14)
|
||
- DB 有数据 → start = max(2023-06-14, max(bar_time) - 2 天)
|
||
- 兜底：start >= end → 跳过这只
|
||
3) 输出"计划"（全量/增量分类、预估请求数、预估耗时）再开始执行
|
||
4) 5 worker × 1 RPS/worker = 5 RPS 总（守住 mairui 上限）
|
||
5) 窗口大小 1 年（mairui 一次最多 ~11600 条）
|
||
|
||
akshare 时代写法：start 写死 2020-01-01 + 4 天窗口，137 小时跑完全市场。
|
||
本版：增量时通常只补最近 1-2 天，~30 分钟。
