Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 架构设计文档
> backend_massive_concurrent — 高并发数据引擎
---
## 一、项目目标
| 目标 | 指标 |
| ----------------- | ----------------------------- |
| 批量抓取吞吐 | ≥ 500 URL/s（网络不限速场景） |
| 聚合查询 P99 延迟 | ≤ 上游最慢接口延迟 + 10ms |
| 文件事件响应延迟 | ≤ 300ms（含防抖） |
| 内存占用 | 万级并发任务下 < 500 MB |
---
## 二、模块划分
### 2.1 数据抓取 (`internal/scraper`)
**核心问题**：大量 URL 需要并发抓取，但必须避免打爆下游或本机资源。
**方案：Worker Pool + 令牌桶**
```
┌─────────────────────────────┐
输入 URL 列表 ──▶ │ Dispatcher（带缓冲 channel） │
└──────────┬──────────────────┘
│ 分发任务
┌───────────────┼───────────────┐
▼ ▼ ▼
Worker #1 Worker #2 ... Worker #N
│ │ │
RateLimiter ──── 令牌桶（全局共享）────
│
http.Client（带超时 & 重试）
│
Result Channel
│
▼
ResultCollector（写入 DB / 内存缓存）
```
**关键设计决策**：
- Worker 数量从 `configs.scraper.worker_pool_size` 读取，运行时可通过 API 动态调整
- 每个 Worker 从 `jobs chan Job` 消费，实现背压（back-pressure）

How to install
mdr add phuhao00/bony-agent/backend_massive_concurrent/docs/DESIGN.md@sha256:59af7d59962a5e08The line at the top of this page pins the label git:20260617.47f66a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
