## 🏗️ 技术方案
|
||
|
||
### 云端版（最优）
|
||
```python
|
||
# 基于Polars（性能极高）
|
||
class ETLEngine:
|
||
def read_excel(self, files: List[File]) -> List[DataFrame]
|
||
def join(self, dfs: List[DataFrame], keys: List[str]) -> DataFrame
|
||
def clean(self, df: DataFrame, rules: Dict) -> DataFrame
|
||
def export(self, df: DataFrame, format: str) -> bytes
|
||
```
|
||
|
||
### 单机版（兼容）
|
||
```python
|
||
# 基于SQLite（内存友好）
|
||
# 分块读取，数据库引擎处理JOIN
|
||
```
