🏗️ 技术方案
云端版（最优）
# 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）
# 基于SQLite（内存友好）
# 分块读取，数据库引擎处理JOIN
