## 什么是 UDF 函数库

对基于时序数据的应用而言，数据质量至关重要。**UDF 函数库** 基于 IoTDB 用户自定义函数 (UDF)，实现了一系列关于数据质量的函数，包括数据画像、数据质量评估与修复等，有效满足了工业领域对数据质量的需求。

## 快速开始

1. 下载包含全部依赖的 jar 包和注册脚本；
2. 将 jar 包复制到 IoTDB 程序目录的`ext\udf`目录下；
3. 运行`sbin\start-server.bat`（在 Windows 下）或`sbin\start-server.sh`（在 Linux 或 MacOS 下）以启动 IoTDB 服务器；
4. 将注册脚本复制到 IoTDB 的程序目录下（与`sbin`目录同级的根目录下），修改脚本中的参数（如果需要）并运行注册脚本以注册 UDF。
