课程概述

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.

The video instruction is not as thorough as I would have liked. The last two weeks of the course material are quite complex in my opinion. The final lab challenges become quite time consuming and difficult because the material was not covered in depth earlier, so my surface understanding of the functions really made me have to do a lot more independent research through youtube for explanations.

The videos and initial exercise are useful, but this is actually pretty tedious for someone who knows SQL and just wants to learn the Spark additions. Also, towards the end, there's typos everywhere.

Not what I expected. Very little discussion of underlying architecture. Simply too many sql exercises. Few typos on the exam. Not very clear. Not sure what I learned even after getting 99%.

1​. there are mistakes in notebooks.

2​. seems that the course isnt updated.

3​. they promise "Associate SQL Analyst"​ certificate, which you dont get it!

Some moe details on Data bricks would have been usefull. Some places important details where missing. Sometimes questions where bit confusing. Especially Week 8

Good hands on course with practical examples about Apache Spark SQL, but the exercises and questions are outdated.

Please update the final test. Some questions requires multiple answers and it is not mentioned in the questions

More explanation helps around advanced constructs. Course more focused on hands on problem solving.

This course is very basic - but if you are willing to read and do hands-on its a good start.

This teaches more about SQL than Apache Spark

Course is pretty hands on that does not give answer right away. You need to find the aswers for the exams from other than course sources. Also some of the assigments are poorly written.

This requires you to sign up and pay for external accounts to complete. I would not sign up for it. Videos are outdated and there is no community edition that is for you to .learn on a limited basis. Outdated.
