Apache Spark is one of the most widely used technologies in big data analytics. In this course, you will learn how to leverage your existing SQL skills to start working with Spark immediately. You will also learn how to work with Delta Lake, a highly performant, open-source storage layer that brings reliability to data lakes. By the end of this course, you will be able to use Spark SQL and Delta Lake to ingest, transform, and query data to extract valuable insights that can be shared with your team....

Content was amazing. Labs were really good. Videos from the lady talking the dense part need to improve. Audio from the lady had a messy stereo, also her pronunciation is not clear. Very bad quality

This course is amazing. The hands on labs was outstanding. But, the audio quality was poor. Needs to improve the audio quality. Overall a great experience learning Apache Spark.

Some assignment / lab questions were messy and/or worded incorrectly but it got the message through. Also, lectures had varying audio volume and quality based on the person talking. Would recommend polishing the questions/lecture audio a bit more. These were just some minor inconveniences. Overall great course with lots of mock real-world examples. Would give it a 4.5 if i could!

Great learning materials and course overall. I do wish they could clean up some minor typos and go over some of the notebooks. Audio on the videos really need some balancing as well (even across presenters). I hope to see better production on the video presentations in the next courses.

Some textual errors and also Final exam question was asking for "YEAR" in one place but obviously had it mixed up with "DAY". Final exam not very clear multiple answers would sometimes be applicable but maybe those were "trick questions" and one should have gotten that

C​ourse is really good, it was nice experience to work with Databricks platform. It has a good balance of theoretical and practical tasks. However quizes are quite simple, and final exam form is not quite good, and final exam tasks contain several critical mistakes.

Excelent to have a good understanding of how Spark and Data Bricks works.

Before start you should know SQL.

This is a hands-on course! I recommend!

Obs.: Databricks and Coursera teams should take a look in forum to solve some issues (bugs).

Good introduction to core topics. A bit confusing at times and could use some clean-up. But overall, I'm really glad I took the course and feel that I understand Spark SQL much better than before. Worth the time and effort.

very nice course, I am a working professional even though many concepts were new for me. Its awesome. But sound quality should be improved, sound just jump from left ear to right ear and then stable, its irritating.

Course is good but lot of cleanup and errors need to be fixed. Final exam it self has incorrect questions. Also someone should be answering the questions raised by students in the forum.

Many of the videos (all that introduced the notebooks) were not necessary and I stopped watching them. The course introduced me to some spark sql functions that I was unaware of.

The material in the course is very good selected for learning Spark SQL. However, it might have been more neat prepared and the questions in quiz and exam could be more difficult

Good Course, Introduces you to the databricks Spark SQL world. I wish there is more practical project and one Advance section of SQL focusing on Windows functions.

The course is great, I think I really learned different skills on spark, the solutions are a powerfull tool to learn. Some videos are not necessary and take time.

The content and hand-on coding is great. The sound recording need improving. It would be better if the coding part including more examples for one function.

V​ery godd course and very informative to a beginner. But i think that the final exam could be lesser extensive.

The notebooks could be more interactive, you just read and press ctrl+enter on the SQL block.

More information about Spark on a practical basis could have been provided.
