This repository contains the code and examples for my article on Medium, which provides an in-depth guide to User-Defined Functions (UDFs) in Apache Spark. You can read the full article here:
A Deeper Look into Spark User-Defined Functions
This article explains User-Defined Functions (UDFs) in Apache Spark. Key topics covered include:
- What are UDFs?: Learn the fundamentals of UDFs and their role in extending Spark's built-in functionality.
- Writing UDFs in Spark: Step-by-step instructions on how to create UDFs in PySpark and Scala, and register them for use in Spark jobs.
The code in this repository allows you to follow along with the examples in the article and provides hands-on demonstration of creating UDFs for Apache Spark.
