🎯 目的:通过DEFINE_INIT宏实现特定的初始化效果,例如红眼睛蓝嘴巴的视觉效果。💻 软件使用步骤: 首先,需要使用User-Defined-Function(UDF)解释(interpreted)或编译(compiled)的.c源文件。 接着,将UDF挂载在User-Defined-Function-Hooks的initialization位置(图3)。只有解释或编译好.c源文件后,edit按钮才会变亮。...
一、UDF介绍 UDF(User Define Function),即用户自定义函数,Spark的官方文档中没有对UDF做过多介绍,猜想可能是认为比较简单吧。 几乎所有sql数据库的实现都为用户提供了扩展接口来增强sql语句的处理能力,这些扩展称之为UDXXX,即用户定义(User Define)的XXX,这个XXX可以是对单行操作的UDF,或者是对多行操作的UDAF,或...
