Acerca del Curso

This course is for students with SQL experience and now want to take the next step in gaining familiarity with distributed computing using Spark. Students will gain an understanding of when to use Spark and how Spark as an engine uniquely combines Data and AI technologies at scale. The four modules build on one another and by the end of the course the student will understand: Spark architecture, Spark DataFrame, optimizing reading/writing data, and how to build a machine learning model. The first module will introduce Spark, including how Spark works with distributed computing and what are Spark Dataframes. Module 2 covers the core concepts of Spark such as storage vs. computing, caching, partitions and Spark UI. The third module looks at Engineering Data Pipelines covering connecting to databases, schemas and type, file formats and writing good data. The final module looks at the application of Spark with Machine Learning through the business use case, a short introduction to what machine learning is, building and applying models and a final course conclusion. By understanding when to use Spark, either scaling out when the model or data is too large to process on a single machine, or having a need to simply speed up to get faster results, students will hone their SQL skills and become a more adept Data Scientist....

Amazing course that really cuts through the fundamentals of using distributed computing power to analyze and manipulate data. Well organised structure on fundamentals

This has been an amazing course. What is worth mentioning is how the content was delivered. Nice hands on. Highly recommended for anyone who is new to Spark

A more appropriate title for the class would be "a brief introduction to Databricks". Very disappointing class. There are Youtube tutorials out there with more content than this class. This is one of the only classes that I have ever taken on Coursera where I could complete 2 weeks worth of all the lectures, assignments, and quizzes in a Sunday afternoon. I think this class was hastily slapped together, there is so little content. If your organization uses Spark and is not a Databricks client (as mine is), you will learn absolutely nothing here. The lectures are extremely short and devoid of any substance. I am still looking for a good online class in Spark. It certainly is not this one.

very superficial using databricks. The courses misses depth to be of any use. It is more a Databricks commercial. Executing pieces of available course without sufficient practice

This course is a great learning source for Distributed Computing with Spark SQL. I got started with course and learnt basic concepts, dos and don'ts.

Concepts are explained well and work notebooks provided needed hands on experience.

Thanks for the course.

Best,

Great course, really well taught and delivered. Only thing I would say is you would really need knowledge of python to really understand this course 100%

Great introduction to Spark SQL and ML Flow. I love that they give extra resources if you want to learn more. It was a fun learning journey.

The information was very beneficial, and the ability to use data bricks

helped put into practice the information learned.

It is a nice experience to learn and a great course to understand the spark's core architecture.

Very great introduction to the Spark SQL and databricks environment worked perfectly as a hands-on.

It would be great if the course covers the Spark ML applications. We used sklearn in the course and utilized a trained model by using the user-defined function. I wonder how it compares with the case where we use Sp ark ML for the training as well.

Positives - Just having SQL knowledge got me to learn how the large data can be processed using SPARKSQL. I had a great time getting hands-on experience for spark SQL notebook.

Negative- I just wish the videos are too paced as there was a lot of information to cover in all the videos.

A good way to get started with Spark SQL. You might need some knowledge of SQL to get started with.

A highly polished presentation, however I still feel only a superficial understanding of partitions and other Spark optimisation techniques. In Course 4 of this Specialization, I had to google myself how best to set partition parameters (ie. how to choose a value) which perhaps shouldve been covered in this course.

High-level definitions are given, but not so much in way of actual application to clarify the concepts.

video quality needs to be improved. Be careful about the last assignment. The accuracy asked in the question is the accuracy over the training data.

great course. but the last assignment has too many coding problems to fix after q2. dont know why
