User-Defined Functions¶

User-defined functions (UDFs) in Snowpark. Refer to UDFRegistration for details and sample code.

Classes

`UserDefinedFunction`(func, return_type, ...)	Encapsulates a user defined lambda or function that is returned by `udf()`, `UDFRegistration.register()` or `UDFRegistration.register_from_file()`.
`UDFRegistration`(session)	Provides methods to register lambdas and functions as UDFs in the Snowflake database.

Methods

`describe`(udf_obj)	Returns a `DataFrame` that describes the properties of a UDF.
`register`(func[, return_type, input_types, ...])	Registers a Python function as a Snowflake Python UDF and returns the UDF.
`register_from_file`(file_path, func_name[, ...])	Registers a Python function as a Snowflake Python UDF from a Python or zip file, and returns the UDF.

Attributes

`func`	The Python function or a tuple containing the Python file path and the function name.
`name`	The UDF name.
