This text is about Consumer Outlined Features (UDFs) in Spark. I’ll undergo what they’re and the way you utilize them, and present you the right way to implement them utilizing examples written in PySpark.
By the way, after I speak about PySpark, I simply imply that the underlying language getting used when programming with Spark is Python. The OG language for growth utilizing Spark was Scala, however with Python’s meteoric rise in reputation, it’s now the primary language individuals use when programming in Spark though Spark itself is written in Scala.
What’s Spark?
In the event you haven’t used or heard of Spark earlier than, the TL;DR is that it’s a highly effective software for processing and analysing giant quantities of information shortly. It’s a distributed computing engine, designed to deal with large knowledge duties by breaking them into smaller items and dealing on them in parallel. This makes it a lot quicker and extra environment friendly than many different strategies, particularly for complicated duties like knowledge evaluation, machine studying, and real-time knowledge processing.
Now a part of the Apache Software program Federation, Spark has a number of key elements that cater to totally different elements of information processing and evaluation, together with elements for Machine Studying, SQL operations and dealing with…
