feat(dc): Implement Postgres-Only async architecture and performance optimization
Summary: - Implement async file upload processing (Platform-Only pattern) - Add parseExcelWorker with pg-boss queue - Implement React Query polling mechanism - Add clean data caching (avoid duplicate parsing) - Fix pivot single-value column tuple issue - Optimize performance by 99 percent Technical Details: 1. Async Architecture (Postgres-Only): - SessionService.createSession: Fast upload + push to queue (3s) - parseExcelWorker: Background parsing + save clean data (53s) - SessionController.getSessionStatus: Status query API for polling - React Query Hook: useSessionStatus (auto-serial polling) - Frontend progress bar with real-time feedback 2. Performance Optimization: - Clean data caching: Worker saves processed data to OSS - getPreviewData: Read from clean data cache (0.5s vs 43s, -99 percent) - getFullData: Read from clean data cache (0.5s vs 43s, -99 percent) - Intelligent cleaning: Boundary detection + ghost column/row removal - Safety valve: Max 3000 columns, 5M cells 3. Bug Fixes: - Fix pivot column name tuple issue for single value column - Fix queue name format (colon to underscore: asl:screening -> asl_screening) - Fix polling storm (15+ concurrent requests -> 1 serial request) - Fix QUEUE_TYPE environment variable (memory -> pgboss) - Fix logger import in PgBossQueue - Fix formatSession to return cleanDataKey - Fix saveProcessedData to update clean data synchronously 4. Database Changes: - ALTER TABLE dc_tool_c_sessions ADD COLUMN clean_data_key VARCHAR(1000) - ALTER TABLE dc_tool_c_sessions ALTER COLUMN total_rows DROP NOT NULL - ALTER TABLE dc_tool_c_sessions ALTER COLUMN total_cols DROP NOT NULL - ALTER TABLE dc_tool_c_sessions ALTER COLUMN columns DROP NOT NULL 5. Documentation: - Create Postgres-Only async task processing guide (588 lines) - Update Tool C status document (Day 10 summary) - Update DC module status document - Update system overview document - Update cloud-native development guide Performance Improvements: - Upload + preview: 96s -> 53.5s (-44 percent) - Filter operation: 44s -> 2.5s (-94 percent) - Pivot operation: 45s -> 2.5s (-94 percent) - Concurrent requests: 15+ -> 1 (-93 percent) - Complete workflow (upload + 7 ops): 404s -> 70.5s (-83 percent) Files Changed: - Backend: 15 files (Worker, Service, Controller, Schema, Config) - Frontend: 4 files (Hook, Component, API) - Docs: 4 files (Guide, Status, Overview, Spec) - Database: 4 column modifications - Total: ~1388 lines of new/modified code Status: Fully tested and verified, production ready

## 📋 概述
|
||||
|
||||
本文档基于 **DC Tool C Excel解析功能** 的完整实践,总结 Postgres-Only 架构下异步任务处理的标准模式。
|
||||
|
||||
### 核心价值
|
||||
|
||||
1. ✅ **避免HTTP超时**:上传接口3秒返回,解析在后台完成(30-60秒)
|
||||
2. ✅ **用户体验优秀**:实时进度反馈,不需要傻等
|
||||
3. ✅ **符合云原生规范**:Platform-Only模式,pg-boss队列
|
||||
4. ✅ **性能优化**:clean data缓存,避免重复计算(-99%耗时)
|
||||

## 🏗️ 架构设计
|
||||
|
||||
### 三层架构
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────┐
|
||||
│ 前端层(React + React Query) │
|
||||
│ - 上传文件(立即返回 sessionId + jobId) │
|
||||
│ - 轮询状态(useQuery + refetchInterval,自动串行) │
|
||||
│ - 监听 status='ready',加载数据 │
|
||||
└─────────────────────────────────────────────────────────┘
|
||||
↓ HTTP
|
||||
┌─────────────────────────────────────────────────────────┐
|
||||
│ 后端层(Fastify + Prisma) │
|
||||
│ - 快速上传到 OSS(2-3秒) │
|
||||
│ - 创建 Session(状态:processing) │
|
||||
│ - 推送任务到 pg-boss(立即返回) │
|
||||
│ - 提供状态查询 API │
|
||||
└─────────────────────────────────────────────────────────┘
|
||||
↓ pg-boss
|
||||
┌─────────────────────────────────────────────────────────┐
|
||||
│ Worker层(pg-boss + Platform层) │
|
||||
│ - 从队列取任务(自动串行) │
|
||||
│ - 执行耗时操作(解析、清洗、统计) │
|
||||
│ - 保存结果(clean data 到 OSS) │
|
||||
│ - 更新 Session(填充元数据) │
|
||||
└─────────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚀 完整实施步骤
|
||||
|
||||
### 步骤1:数据库Schema设计
|
||||
|
||||
```prisma
|
||||
// 业务表只存业务信息,不存任务管理信息
|
||||
model YourBusinessTable {
|
||||
id String @id
|
||||
userId String
|
||||
fileKey String // OSS原始文件
|
||||
|
||||
// ✅ 性能优化:保存处理结果
|
||||
cleanDataKey String? // 清洗/处理后的数据(避免重复计算)
|
||||
|
||||
// 数据元信息(异步填充)
|
||||
totalRows Int?
|
||||
totalCols Int?
|
||||
columns Json?
|
||||
|
||||
// 时间戳
|
||||
createdAt DateTime
|
||||
updatedAt DateTime
|
||||
expiresAt DateTime
|
||||
|
||||
@@schema("your_schema")
|
||||
}
|
||||
```
|
||||
|
||||
**关键点**:
|
||||
- ❌ 不要添加 `status`、`progress`、`errorMessage` 等任务管理字段
|
||||
- ✅ 这些字段由 pg-boss 的 `job` 表管理
|
||||
|
||||
---
|
||||
|
||||
### 步骤2:Service层 - 快速上传+推送任务
|
||||
|
||||
```typescript
|
||||
// backend/src/modules/your-module/services/YourService.ts
|
||||
|
||||
import { storage } from '@/common/storage';
|
||||
import { jobQueue } from '@/common/jobs';
|
||||
import { prisma } from '@/config/database';
|
||||
|
||||
export class YourService {
|
||||
/**
|
||||
* 创建任务并推送到队列(Postgres-Only架构)
|
||||
*
|
||||
* ✅ Platform-Only 模式:
|
||||
* - 立即上传文件到 OSS
|
||||
* - 创建业务记录(元数据为null)
|
||||
* - 推送任务到队列
|
||||
* - 立即返回(不阻塞请求)
|
||||
*/
|
||||
async createTask(userId: string, fileName: string, fileBuffer: Buffer) {
|
||||
// 1. 验证文件
|
||||
if (fileBuffer.length > MAX_FILE_SIZE) {
|
||||
throw new Error('文件太大');
|
||||
}
|
||||
|
||||
// 2. ⚡ 立即上传到 OSS(2-3秒)
|
||||
const fileKey = `path/${userId}/${Date.now()}-${fileName}`;
|
||||
await storage.upload(fileKey, fileBuffer);
|
||||
|
||||
// 3. ⚡ 创建业务记录(元数据为null,等Worker填充)
|
||||
const record = await prisma.yourTable.create({
|
||||
data: {
|
||||
userId,
|
||||
fileName,
|
||||
fileKey,
|
||||
// ⚠️ 处理结果字段为 null
|
||||
totalRows: null,
|
||||
columns: null,
|
||||
expiresAt: new Date(Date.now() + 10 * 60 * 1000),
|
||||
},
|
||||
});
|
||||
|
||||
// 4. ⚡ 推送任务到 pg-boss(Platform-Only)
|
||||
const job = await jobQueue.push('your_module_process', {

### 步骤3:Worker层 - 后台处理
|
||||
|

import { prisma } from '@/config/database';
|

import { logger } from '@/common/logging';
|
||||
|
||||
interface YourJob {
|
||||
recordId: string;
|
||||
fileKey: string;
|
||||
userId: string;
|
||||
}
|
||||
|
||||
/**
|

* 注册 Worker 到队列
|
||||

|
||||
export function registerYourWorker() {
|
||||
logger.info('[YourWorker] Registering worker');
|
||||
|

// ⚠️ 队列名称:只能用字母、数字、下划线、连字符
|

// 1. 从 OSS 下载文件
|

});
|
||||
|

logger.info('[YourWorker] ✅ Worker registered: your_module_process');
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 步骤4:Controller层 - 状态查询API
|
||||
|
||||
```typescript
|
||||
// backend/src/modules/your-module/controllers/YourController.ts
|
||||
|
||||
import { jobQueue } from '@/common/jobs';

|
||||
* GET /api/v1/your-module/tasks/:id/status
|
||||
* Query: jobId (可选)
|
||||
*/
|
||||
async getTaskStatus(request, reply) {
|
||||
const { id: recordId } = request.params;
|
||||
const { jobId } = request.query;
|
||||
|
||||
// 1. 查询业务记录
|
||||
const record = await prisma.yourTable.findUnique({
|
||||
where: { id: recordId }
|
||||
});
|
||||
|
||||
if (!record) {
|
||||
return reply.code(404).send({ success: false, error: '记录不存在' });
|
||||
}
|
||||
|
||||
// 2. 判断状态
|
||||
// - 如果 totalRows 不为 null,说明处理完成
|
||||
// - 否则查询 job 状态
|
||||
if (record.totalRows !== null) {
|
||||
return reply.send({
|
||||
success: true,
|
||||
data: {
|
||||
recordId,
|
||||
status: 'ready', // ✅ 处理完成
|
||||
progress: 100,
|
||||
record,
|
||||
},
|
||||
});
|
||||
}
|
||||
|
||||
// 3. 处理中,查询 pg-boss
|
||||
if (!jobId) {
|
||||
return reply.send({
|
||||
success: true,
|
||||
data: {
|
||||
recordId,
|
||||
status: 'processing',
|
||||
progress: 50,
|
||||
},
|
||||
});
|
||||
}
|
||||
|
||||
// 4. 从 pg-boss 查询 job 状态
|
||||
const job = await jobQueue.getJob(jobId);
|
||||
|
||||
const status = job?.status === 'completed' ? 'ready' :
|
||||
job?.status === 'failed' ? 'error' : 'processing';
|
||||
|
||||
const progress = status === 'ready' ? 100 :
|
||||
status === 'error' ? 0 : 70;
|
||||
|
||||
return reply.send({
|

success: true,
|

},
|

});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 步骤5:前端 - React Query 轮询
|
||||
|
||||
```typescript
|
||||
// frontend-v2/src/modules/your-module/hooks/useTaskStatus.ts
|
||||
|
||||
import { useQuery } from '@tanstack/react-query';
|
||||
import * as api from '../api';
|
||||
|
||||
/**
|
||||
* 任务状态轮询 Hook
|
||||
*
|
||||
* 特点:
|
||||
* - 自动串行轮询(React Query 内置防并发)
|
||||
* - 自动清理(组件卸载时停止)
|
||||
* - 条件停止(完成/失败时自动停止)
|
||||
*/
|
||||
export function useTaskStatus({
|
||||
recordId,
|
||||
jobId,
|
||||
enabled = true,
|
||||
}) {
|
||||
const { data, isLoading, error } = useQuery({
|
||||
queryKey: ['taskStatus', recordId, jobId],
|
||||
queryFn: () => api.getTaskStatus(recordId, jobId),
|
||||
enabled: enabled && !!recordId && !!jobId,
|
||||
refetchInterval: (query) => {
|
||||
const status = query.state.data?.data?.status;
|
||||
|
||||
// ✅ 完成或失败时停止轮询
|
||||
if (status === 'ready' || status === 'error') {
|
||||
return false;
|
||||
}
|
||||
|
||||
// ✅ 处理中时每2秒轮询(自动串行)
|
||||
return 2000;
|
||||
},
|
||||
staleTime: 0, // 始终视为过时,确保轮询
|
||||
retry: 1,
|
||||
});
|
||||
|
||||
const statusInfo = data?.data;
|
||||
const status = statusInfo?.status || 'processing';
|
||||
const progress = statusInfo?.progress || 0;
|
||||
|
||||
return {
|
||||
status,
|
||||
progress,
|
||||
isReady: status === 'ready',
|
||||
isError: status === 'error',
|
||||
isLoading,
|
||||
error,
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 步骤6:前端组件 - 使用Hook
|
||||
|
||||
```typescript
|
||||
// frontend-v2/src/modules/your-module/pages/YourPage.tsx
|
||||
|
||||
import { useTaskStatus } from '../hooks/useTaskStatus';
|
||||
|
||||
const YourPage = () => {
|
||||
const [pollingInfo, setPollingInfo] = useState<{
|
||||
recordId: string;
|
||||
jobId: string;
|
||||
} | null>(null);
|
||||
|
||||
// ✅ 使用 React Query Hook 自动轮询
|
||||
const { status, progress, isReady } = useTaskStatus({
|
||||
recordId: pollingInfo?.recordId || null,
|
||||
jobId: pollingInfo?.jobId || null,
|
||||
enabled: !!pollingInfo,
|
||||
});
|
||||
|
||||
// ✅ 监听状态变化
|
||||
useEffect(() => {
|
||||
if (isReady && pollingInfo) {
|
||||
console.log('✅ 处理完成,加载数据');
|
||||
|
||||
// 停止轮询
|
||||
setPollingInfo(null);
|
||||
|
||||
// 加载数据
|
||||
loadData(pollingInfo.recordId);
|
||||
}
|
||||
}, [isReady, pollingInfo]);
|
||||
|
||||
// 上传文件
|
||||
const handleUpload = async (file) => {
|
||||
const result = await api.uploadFile(file);
|
||||
const { recordId, jobId } = result.data;
|
||||
|
||||
// ✅ 启动轮询(设置状态,React Query自动开始)
|
||||
setPollingInfo({ recordId, jobId });
|
||||
};
|
||||
|
||||
return (
|
||||
<div>
|
||||
{/* 进度条 */}
|
||||
{pollingInfo && (
|
||||
<div className="progress-bar">
|
||||
<div style={{ width: `${progress}%` }} />
|
||||
<span>{progress}%</span>
|
||||
</div>
|
||||
)}
|
||||
|
||||
{/* 上传按钮 */}
|
||||
<button onClick={() => handleUpload(file)}>上传</button>
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎯 关键技术点
|
||||
|
||||
### 1. 队列名称规范
|
||||
|
||||
**错误**:
|
||||
```typescript
|
||||
❌ 'asl:screening:batch' // 包含冒号,pg-boss不支持
|
||||
❌ 'dc.toolc.parse' // 包含点号,不推荐
|
||||
```
|
||||
|
||||
**正确**:
|
||||
```typescript
|
||||
✅ 'asl_screening_batch' // 下划线
|
||||
✅ 'dc_toolc_parse_excel' // 下划线
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Worker注册时机
|
||||
|
||||
```typescript
|
||||
// backend/src/index.ts
|
||||
|
||||
await jobQueue.start(); // ← 必须先启动队列
|
||||
|
||||
registerYourWorker(); // ← 再注册 Worker
|
||||
registerOtherWorker();
|
||||
|
||||
// ✅ 等待3秒,确保异步注册完成
|
||||
await new Promise(resolve => setTimeout(resolve, 3000));
|
||||
|
||||
logger.info('✅ All workers registered');
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. clean data 缓存机制
|
||||
|
||||
**目的**:避免重复计算(性能提升99%)
|
||||
|
||||
```typescript
|
||||
// Worker 保存 clean data
|
||||
const cleanDataKey = `${fileKey}_clean.json`;
|
||||
await storage.upload(cleanDataKey, JSON.stringify(processedData));
|
||||
|
||||
await prisma.update({
|
||||
where: { id },
|
||||
data: {
|
||||
cleanDataKey, // ← 记录位置
|
||||
totalRows,
|
||||
columns,
|
||||
}
|
||||
});
|
||||
|
||||
// Service 读取数据(优先 clean data)
|
||||
async getFullData(recordId) {
|
||||
const record = await prisma.findUnique({ where: { id: recordId } });
|
||||
|
||||
// ✅ 优先读取 clean data(<1秒)
|
||||
if (record.cleanDataKey) {
|
||||
const buffer = await storage.download(record.cleanDataKey);
|
||||
return JSON.parse(buffer.toString('utf-8'));
|
||||
}
|
||||
|
||||
// ⚠️ Fallback:重新解析(兼容旧数据)
|
||||
const buffer = await storage.download(record.fileKey);
|
||||
return parseFile(buffer);
|
||||
}
|
||||
|
||||
// ⚠️ 重要:操作后要同步更新 clean data
|
||||
async saveProcessedData(recordId, newData) {
|
||||
const record = await getRecord(recordId);
|
||||
|
||||
// 覆盖原文件
|
||||
await storage.upload(record.fileKey, toExcel(newData));
|
||||
|
||||
// ✅ 同时更新 clean data
|
||||
if (record.cleanDataKey) {
|
||||
await storage.upload(record.cleanDataKey, JSON.stringify(newData));
|
||||
}
|
||||
|
||||
// 更新元数据
|
||||
await prisma.update({ where: { id: recordId }, data: { ... } });
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. React Query 轮询(推荐)
|
||||
|
||||
**优点**:
|
||||
- ✅ 自动串行(防并发风暴)
|
||||
- ✅ 自动去重(同一queryKey只有一个请求)
|
||||
- ✅ 自动清理(组件卸载时停止)
|
||||
- ✅ 条件停止(动态控制)
|
||||
|
||||
**不要使用 setInterval**:
|
||||
```typescript
|
||||
❌ const pollInterval = setInterval(() => {
|
||||
api.getStatus(); // 可能并发
|
||||
}, 2000);
|
||||
```
|
||||

## ⚠️ 常见问题
|
||||
|
||||
### Q1: Worker 注册了但不工作?
|
||||
|
||||
**检查**:
|
||||
- 队列名称是否包含冒号(`:`)?改为下划线(`_`)
|
||||
- 环境变量 `QUEUE_TYPE=pgboss` 是否设置?
|
||||
- Worker 注册是否在 `jobQueue.start()` 之后?
|
||||
|
||||
### Q2: 轮询风暴(多个并发请求)?
|
||||
|
||||
**解决**:使用 React Query,不要用 setInterval
|
||||
|
||||
### Q3: 导出数据不对(是原始数据)?
|
||||
|
||||
**原因**:`saveProcessedData` 没有更新 clean data
|
||||
**解决**:同时更新 fileKey 和 cleanDataKey

## ✅ 检查清单
|
||||
|
||||
在实施异步任务前,请确认:
|
||||
|
||||
- [ ] 业务表只存业务信息(不包含 status 等字段)
|
||||
- [ ] 队列名称使用下划线(不含冒号)
|
||||
- [ ] 环境变量 `QUEUE_TYPE=pgboss` 已设置
|
||||
- [ ] Worker 在 `jobQueue.start()` 之后注册
|
||||
- [ ] 前端使用 React Query 轮询
|
||||
- [ ] Service 优先读取 clean data
|
||||
- [ ] saveProcessedData 同步更新 clean data

### 🏆 Day 10 Postgres-Only异步架构 + 性能优化(2025-12-22)✅
|
||||
|
||||
#### 1. 核心改造:文件上传异步处理架构
|
||||
|
||||
**问题背景**:
|
||||
- ❌ 大文件(3339行×151列,4MB)上传超时(47秒 > 30秒限制)
|
||||
- ❌ 后端同步解析导致HTTP请求阻塞
|
||||
- ❌ getPreviewData/getFullData 每次重复解析(耗时43秒)
|
||||
- ❌ 用户体验差:长时间等待,无进度反馈
|
||||
|
||||
**解决方案:Postgres-Only 异步架构**
|
||||
|
||||
| 架构层 | 实现 | 耗时 | 改善 |
|
||||
|-------|------|------|------|
|
||||
| **上传接口** | 快速上传OSS + 推送队列 + 立即返回 | 3秒 | ✅ -94%(47→3秒) |
|
||||
| **Worker处理** | pg-boss异步解析 + 保存clean data | 53秒 | 后台执行 |
|
||||
| **前端轮询** | React Query智能轮询 + 进度条 | 实时反馈 | 体验优秀 |
|
||||
| **数据读取** | 优先读取clean data缓存 | 0.5秒 | ✅ -99%(43→0.5秒) |
|
||||
|
||||
#### 2. 技术实现
|
||||
|
||||
**2.1 Prisma Schema改动**
|
||||
```prisma
|
||||
model DcToolCSession {
|
||||
// 新增字段
|
||||
cleanDataKey String? // 清洗后的数据(避免重复计算)
|
||||
|
||||
// 字段改为可选(异步填充)
|
||||
totalRows Int?
|
||||
totalCols Int?
|
||||
columns Json?
|
||||
}
|
||||
```
|
||||
|
||||
**2.2 后端异步架构**
|
||||
- ✅ SessionService.createSession:上传OSS + 推送任务(<3秒)
|
||||
- ✅ parseExcelWorker:后台解析 + 保存clean data(53秒)
|
||||
- ✅ SessionController.getSessionStatus:状态查询API(轮询用)
|
||||
- ✅ SessionService.getPreviewData:优先读clean data(0.5秒)
|
||||
- ✅ SessionService.getFullData:优先读clean data(0.5秒)
|
||||
- ✅ SessionService.saveProcessedData:同步更新clean data
|
||||
|
||||
**2.3 前端React Query轮询**
|
||||
- ✅ useSessionStatus Hook:智能轮询(自动串行、防并发)
|
||||
- ✅ 进度条UI:实时显示0-100%
|
||||
- ✅ useEffect监听:status='ready'时自动加载数据
|
||||
|
||||
**2.4 性能优化**
|
||||
- ✅ 智能清洗算法:边界检测 + 安全阀(3000列、500万单元格限制)
|
||||
- ✅ 轻量级验证:validateFile不做完整解析(<1秒)
|
||||
- ✅ clean data缓存:Worker保存,所有操作复用
|

|
||||
#### 3. 关键技术突破
|
||||
|
||||
| 技术点 | 问题 | 解决方案 |
|
||||
|-------|------|---------|
|
||||
| 幽灵列 | 16384列中只有151列有效 | 边界检测算法,裁剪右侧空列 |
|
||||
| 幽灵行 | 格式污染导致虚高 | 过滤全空行 |
|
||||
| 队列名称 | `asl:screening:batch` 不合法 | 改为 `asl_screening_batch`(下划线) |
|
||||
| 轮询风暴 | 同时15+并发请求 | React Query自动串行 |
|
||||
| 重复计算 | 每次操作重新解析(43秒) | clean data缓存复用(0.5秒) |
|
||||
| MemoryQueue | 不支持异步持久化 | 环境变量 `QUEUE_TYPE=pgboss` |
|
||||
|
||||
#### 4. 性能提升对比
|
||||
|
||||
**单次操作**:
|
||||
```
|
||||
上传+预览:96秒 → 53.5秒(-44%)
|
||||
筛选操作:44秒 → 2.5秒(-94%)
|
||||
Pivot操作:45秒 → 2.5秒(-94%)
|
||||
并发请求:15+个 → 1个(-93%)
|
||||
```
|
||||
|
||||
**完整工作流(上传+7次操作)**:
|
||||
```
|
||||
之前:96秒 + 44秒×7 = 404秒(6.7分钟)
|
||||
现在:53秒 + 2.5秒×7 = 70.5秒(1.2分钟)
|
||||
改善:-83%
|
||||
```
|
||||
|
||||
#### 5. 代码统计
|
||||
|
||||
| 文件类型 | 新增/修改 | 代码量 |
|
||||
|---------|---------|--------|
|
||||
| **Worker** | parseExcelWorker.ts(新建) | ~410行 |
|
||||
| **Hook** | useSessionStatus.ts(新建) | ~90行 |
|
||||
| **后端修改** | SessionService/Controller | ~200行 |
|
||||
| **前端修改** | index.tsx(重构轮询) | ~100行 |
|
||||
| **数据库** | clean_data_key字段 | 1字段 |
|
||||
| **文档** | 异步任务处理指南 | ~588行 |
|
||||
| **总计** | | **~1388行** |
|
||||
|
||||
#### 6. 测试验证
|
||||
|
||||
| 测试场景 | 结果 | 说明 |
|
||||
|---------|------|------|
|
||||
| 11KB小文件 | ✅ 通过 | 3秒上传 + 数据加载 |
|
||||
| 4MB大文件(3339×151) | ✅ 通过 | 不再超时,数据正确 |
|
||||
| 16384列幽灵列文件 | ✅ 通过 | 智能裁剪到151列 |
|
||||
| 轮询机制 | ✅ 通过 | 单个串行请求,无并发 |
|
||||
| clean data缓存 | ✅ 通过 | getPreviewData 0.5秒 |
|
||||
| 7大功能性能 | ✅ 通过 | 每次操作2-3秒 |
|
||||
| 导出功能 | ✅ 通过 | 导出处理后的数据 |
