AnnotationsUDF's generalized representation represents a collection of custom scalar functions, custom aggregate functions, and custom functions of three types of customized table functions. In a narrow sense, only user-defined scalar functions are represented. The document often uses this term,

Use MySQL to improve Permissions

I had a webshell tutorial on the Internet with a weak MySQL password. But what I want to talk about this time is not to get webshell, but to directly get system permissions. I can see it clearly. It is to get it directly! First, let me briefly talk about the process of obtaining system permissions with a weak MySQL password: first, use the MySQL script to upload the udf dll file, then use the function Self-

MaxCompute Studio improves the UDF and MapReduce development experience. UDF stands for User-Defined Function. MaxCompute provides many built-in functions to meet your computing needs. You can also create custom functions to meet your customized computing needs. There are three types of udfs that can be expanded by users: User-Defined Scalar Function, User-Defined Table Valued Function, and User-Defined Agg

Hive User-Defined UDF and aggregate function UDAF

Hive is a data warehouse built on Hadoop. Hive converts SQL queries into a series of MapReduce jobs running in Hadoop clusters, which is a high-level abstraction of MapReduce, you do not need to write specific MapReduce methods. Hive organizes data into tables, so that the data on HDFS has a structure. The metadata, that is, the table mode, is stored in the database named metastore. You can directly use dfs in the hive shell environment to access hadoop's fi
