Great introduction to Spark and it's data structures. The course is easy to follow, and lecturer is entertaining and really engaged.

Thanks, I really had fun !

I worked with PySpark professionally, and this helped add some depth to my knowledge of Spark as well as give me a chance to translate those skills to Scala.

Clear explanations, with emphasis done on the important/practical stuff. From zero to a general understanding on Spark and the available tools in 4 weeks.

Lectures were clear and engaging and directly related to the homework. The assignments were very practical and very hard. Best course of the series!

Some of the assignments are a bit challenging, due to grading system I suppose, but in the end general impression about this course is very positive

Amazing technology, explained wonderfully. Note: familiarity with scala (take Martin's course in coursera) would make your experience even better.

good stuff, compared to the other similar course in PySpark this one gave me a lot more understanding of how things work in Spark on the low level

Very useful. Dr. Miller apparently did a very good job. I strongly suggest beginners to read the "Learning Spark" book and then take this class.

Very well-organized courses about Spark ! Really learned some good practical tips. Hope there could be more explanations about the assignments.

Yet another excellent Scala class. Good lectures, good assignments. Clear and understandable, while presenting a whole bunch of new concepts.

Really clear and direct. Would love to see another course on the Advanced Spark topics such as Spark Streaming and Spark custom libraries

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.

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!

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.
