Useful practical course, especially about performance optimization. Window functions have many options, it would be nice to add window size description with practical examples or links to them.
I really appreciated all of the labs that went along with this course. They were detailed and thorough and led us through some advanced concepts in a digestible, understandable fashion.

the course needs more labs more extense and deep, in order to have a real knoledge. This course only introduce tools and concpets but you must touch more in order to really understand.

Instructor needs to speak up and slow down. H mumbles over important concepts and pauses on unimportant topics. His explanations do not help answering module quiz on several occasions.
