DESCRIPTION:As data engineers\, we are used to spinning up a Spark Cluster 
 every time we want to do data processing and handle the overhead that come
 s with using such a mighty framework. But is this really necessary? In thi
 s talk I will argue that single-node processing with Polars is in many cas
 es easier and cheaper. I will compare a typical ETL & Feature Engineering 
 task in Spark and in Polars and offer a pragmatic opinion on when to use o
 ne or the other.
