MaxCompute - Supports SQL Functions
Jul 24 2020MaxCompute
Target customers: developers. Features released: MaxCompute UDFs support Java and Python. Some UDFs can be directly implemented by SQL. Therefore, MaxCompute supports SQL functions. This eliminates the need for complex operations, such as compiling Java UDFs, adding resources, and creating functions. This also improves the readability and reuse rate of SQL code. MaxCompute SQL allows you to use SQL functions. The following functions can be used as input parameters of SQL functions: built-in functions, UDFs, and SQL functions. Anonymous functions can also be used as input parameters of SQL functions. SQL functions allow you to express business logic more flexibly, which makes up for the disadvantage that UDFs can only be written in Java or Python.
