The professor and her team has done a tremendous job in this course. A very hearty thank you to all of you. Please keep up the good work!

A great introduction to Spark !!! An esential course to anyone interested in the field! Thank you very much Heather and the EPFL team !!

FANTASTIC!!! I don't even know which was better: the course material quality, the instructor's approach or the assignments. FANTASTIC!!!

This is a good course if you already know the Scala language and looking to improve your theoretical understanding of Spark programming.

It gave me very good understanding on Spark Architecture, functioning along with hands on over Scala. Good examples used during lessons.

First weeks were overcomplicated with k-means and stuff not related to Spark itself.

In general - GREAT JOB !!! Thx for such kind courses

Excellent explanations by Heather Miller. She really knows how to explain a topic, and also makes the lectures a lot of fun to listen !

Awesome Course . Detail and Depth of RDD vs Dataframe vs Dataset.

Latency vs Network/IO vs Shuffling.

Learnt a lot .

Thank you Heather.

Very well taught and insightful! Especially the combination of slides, and additionally drawn notes on that slides, I found very good.

Interesting and useful course. Could be better if the videos were not as blurred, which made it sometimes hard to read the slides.

Awesome video lectures by the instructor. The content is very good and i fee i gained good knowledge. I really loved the series.

Great lesson, the instructor is doing a great job explaining all concepts and using intuitive examples when needed. Thank you!

It was short and sweet. However, I wish the assignments had more unit tests to fill gaps where the instructions weren't clear.

Challenging but very enlightening. Requires you to read the docs and figure out a lot of stuff on your own. My kind of course!

Instructor does a great job of explaining the material and keeping students' interest. Good explanations and use of examples.

An excellent explanation of basic concepts of Spark using Scala. We covered the most important topics and ready to deep dive!

Very good and interesting videos. Really clear explanations. Practice part worse, but Forum helps with all misunderstandings.

Excellent. I learned a lot from this course, even though I did not know much about scala. Strongly recommended this course

Pretty nice course. But with one comment on the grading system, sometime the comment & message is not that intuitive enough.

Very complet and accurate about Spark with Scala. Maybe an assignement with MongoDB or the like would be a plus

Thank you

Amazing lectures, and challenging tasks to do on the way. I really enjoyed going through the course, and I learned a lot.

It is a course well organized, full of useful notions e with good assignments to assess your progress in learning stuff.

I loved this course! One of my preferred courses so far. Very engaging and greatly explained! 5 stars totally deserved.

Muy bueno, Excelente. Todos los conocimientos obtenidos me serán de mucha ayuda en mi camino hacia el mundo de Big Data

Really helpful, it's a really good way to get to know how spark works as well as a good round up on basic data mining.
