As you can see in the video, I built a web-based app that lets you practice both Spark SQL and the DataFrame API without any setup.
It’s just like you do LeetCode, read, understand the problem, type some code, and hit submit to see the result.
You can visit spark.vutrinh.net to try the first 5 problems for FREE.

If you’re already a paid member, just visit spark.vutrinh.net, sign up, and log in with your sub email.
Thus, I invite you to become one:
