It was a neat lecture! I was able to neatly organize the overall concept of how to handle concurrency issues. It felt like it was a step-by-step lecture on how to solve concurrency issues from the basics, so it was a good lecture to grasp the basic concepts. (java ➡️ db ➡️ redis) I think it is a good lecture to organize for those who are new to concurrency issues. I think it was better because the lecture was organized with springboot, which I usually use. Please continue to make good lectures in the future!
