Taming Big Data with Apache Spark and Python

Very well rated course, but I wonder given how fast things are going in the area of ​​computer technology (and the fact that this course was developed over 5 years ago, I think) if anyone who has taken the course can comment on how timely and relevant the course is. the information is available today i.e. the course uses Spark 2 when the latest version is 3, and seems to have a really long section on RDDs, but I thought I heard that RDDs do not 'were more beneficial and that the IT frameworks are there, they are. Basically, I try to use my learning as effectively as possible.
