Well... If you don't have a basic understanding of data structures and databases, you will have a hard time understanding the lecture. The lecture itself is good for quickly learning the flow, but there is a lot of talk, but only one data is displayed on the screen in the form of a picture, and there is no example or explanation section, so I had to turn on the subtitles and listen to it, and solve all the questions I had by googling. I think I spent more than 3 times the lecture time, half GPT time, and half googling. The depth of the talk is there, but there is a lack of data, so I had to google a lot to understand it. I think it was not bad because I learned things I didn't know, but I think it would be better if you paid a little more attention to the data part. Of course, people who learn Redis won't listen without knowing anything about programming, so I hope you just take my review as a reference.
