À propos du cours

Manipulating big data distributed over a cluster using functional concepts is rampant in industry, and is arguably one of the first widespread industrial uses of functional ideas. This is evidenced by the popularity of MapReduce and Hadoop, and most recently Apache Spark, a fast, in-memory distributed collections framework written in Scala. In this course, we'll see how the data parallel paradigm can be extended to the distributed case, using Spark throughout. We'll cover Spark's programming model in detail, being careful to understand how and when it differs from familiar programming models, like shared-memory parallel collections or sequential Scala collections. Through hands-on examples in Spark and Scala, we'll learn when important issues related to distribution like latency and network communication should be considered and how they can be addressed effectively for improved performance. Learning Outcomes. By the end of this course you will be able to: - read data from persistent storage and load it into Apache Spark, - manipulate data with Spark and Scala, - express algorithms for data analysis in a functional style, - recognize how to avoid shuffles and recomputation in Spark, Recommended background: You should have at least one year programming experience. Proficiency with Java or C# is ideal, but experience with other languages such as C/C++, Python, Javascript or Ruby is also sufficient. You should have some familiarity using the command line. This course is intended to be taken after Parallel Programming:

The sessions where clearly explained and focused. Some of the exercises contained slightly confusing hints and information, but I'm sure those mistakes will be ironed out in future iterations. Thanks!

Excellent overview of Spark, including exercises that solidify what you learn during the lectures. The development environment setup tutorials were also very helpful, as I had not yet worked with sbt.

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.

Specially the last lectures where useful. but there is quite some gap between the lectures and practical task.

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

Very good and knowledgeable course. It basically explains about spark core, dataframe, dataset and spark sql.

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.

Good stuff, well presented, but the instructor takes no risks to explain more complex details.

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