Unlocking the Power of PySpark: A Comprehensive Workshop
Carsten Frommhold

Are you struggling with big data in your business? Join us to discover how PySpark can help you solve your problems efficiently and effectively. In this workshop, we will revisit the key concepts of PySpark, including parallel processing and lazy evaluation. We will explore DataFrames as a convenient layer of so called RDDs and work with an optimizer to get the most out of our transformations.

We'll also take a look the Spark UI, which allows us to monitor and optimize our processes. To put our knowledge into practice, we'll simulate a business problem and walk through the entire process of data preparation (preprocessing), training a model with MLLib, and performing inference on preprocessed test data. We'll also add a business logic layer to our solution for further customization (postprocessing).

Optional content includes lessons learned from large-scale production systems based on PySpark. We'll share insights on how to optimize performance and scale your solution to handle big data with ease.
