A function that you define yourself in a program is known as user defined function. You can give any name to a user defined function, however you cannot use thePython keywordsas function name. In python, we define the user-defined function usingdefkeyword, followed by the function name. Fu...
DLI supports the following three types of user-defined functions (UDFs):Regular UDF: takes in one or more input parameters and returns a single result.User-defined table-
This feature is in Public Preview in Databricks Runtime 14.3 LTS and above.A user-defined table function (UDTF) allows you to register functions that return tables instead of scalar values. Unlike scalar functions that return a single result value from each call, each UDTF is invoked in a SQ...

特征处理层(spark dataframe):这里操作的目标是已经结构化的dataframe,在特称处理过程中需要进行udf函数来进行特征工程,同时由于有些场景结合group by一起使用,衍生出了UADF(user aggregate defined function) 管道对udf的封装(pipline):这里我们已经将模型的处理和训练写好了,这时候假如我们想将这些对数据操作封装成pi...
