“You get small lessons and can practice skills right away. It’s so convenient. Committing to Dataquest was an easy decision.”
You’ll learn how to start multiple processes and run functions on multiple processes at the same time, as well as share data between multiple processes. You’ll also learn how to use a process pool executor, and you’ll practice all of these skills as you explore data about the demand for data engineering jobs. Finally, you’ll learn how to use process pools, how to actually implement MapReduce, and how to effectively process data with it.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. At the end of the course, you’ll complete a project using your new skills that challenges you to explore data from Wikipedia pages and analyze it quickly and efficiently using MapReduce.
