DuckDB SQL 分析引擎
用 SQL 直接查询 CSV、Parquet、JSON 文件,无需导入数据库。适合大数据集分析。
使用场景
- 用户说「用 SQL 分析这个 CSV 文件」「这个数据集有多少行」
- 数据量大(>10万行),excel-analyzer 处理较慢时
- 用户需要复杂聚合、JOIN、窗口函数等 SQL 功能
- 用户说「对比这两个 CSV 文件的差异」
与 excel-analyzer 的区别
| 工具 | 擅长 | 局限 |
|---|---|---|
| excel-analyzer | 小数据集、图表、格式化输出 | 大数据集慢 |
| duckdb-sql | 大数据集、复杂 SQL、多文件 JOIN | 不做格式化输出 |
