“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”

Course overview

Big data is all around us, and Spark is quickly becoming an in-demand Big Data tool that employers want to see.
In this course, you’ll learn the advantages of Apache Spark. You’ll learn concepts such as Resilient Distributed Datasets (RDDs), Spark SQL, Spark DataFrames, and the difference between pandas and Spark DataFrames.

You’ll also learn how to install Spark and PySpark, a Python API that allows you to interact with Spark using Python code. You’ll learn how to integrate PySpark with Jupyter Notebook so you can analyze large datasets.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. You’ll work with a variety of real-world datasets, including the text of Hamlet, census data, and guest data from The Daily Show.

Key skills

Breaking down tasks using the map-reduce framework
Processing and transforming larger, raw files using Spark
Working with large, unstructured datasets using Spark SQL and Spark DataFrames

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”

Jessica Ko

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”
