I think this is the first lecture that delves into Redis in such detail in code. It was impressive that he actually implemented the caching strategy and its advantages and disadvantages, rather than just talking about it, using Spring and Java code that I was somewhat familiar with. Personally, I think it was very helpful. It was a lecture that I felt tried to explain in a more familiar and easy-to-understand way, rather than wrapping it up in difficult terms. Thank you for the great lecture, instructor.
