although spark part is taught nicely, it also takes a lot of time to understand the sql part and remember a lot of sql operations as a zero background man in sql

goot as introduction about spark and big data. Small notice: it is incorrect to compare performance hadoop and spark. As I understand, spark was expected to be compacred with MapReduce.

With this course, I surely improved my knowledge about Spark... But I am still thinking that Spark is an overly intricate framework.

I love the indepth aproach at the RDDs. I'd say DataFrames and DataSets required a bit more examples and testing material though.

Quizzes in the lecture videos would be nice. Also more, but shorter videos would be enjoyable. Programming assignments very nice!

The video speed is way to fast, this woman is speaking really fast, first as i slowed the video down at 75% was its ok.

Good course. Could be more comprehensive about analysis. Content is all video and Lecture notes would be nice.

Good introduction to Spark. One thing that I didn't like was use of simple Ints and Strings instead of types.

Learned a lot of new things, but I would have focused on more but shorter and more variegate assignments.

Bien mais j'aurais aimé avoir plus d'exercices pour s'entrainer sur les dataframes / datasets

A good course to know about how spark works but not how to use it, I like this!

Nice course, could use little fixes. Sometimes practice goes ahead of theory

Sometimes the labs included techniques not fully covered by the lectures.
