I started taking the course on April 22nd and finished it all today, so I guess I spent about a month and a half with Kooke-nim. Kafka was a technology I didn't pay much attention to after briefly encountering it during my undergraduate years, but through this course, I was able to actually apply it to Spring and learned about indexes, various locks, and how to handle large-scale traffic, which was truly beneficial. I felt that if Kooke-nim's other courses are released in the future, I would definitely want to take them. Of course, from the perspective of someone preparing for a job, Kafka might feel like a rather advanced technology, and that point was a bit of a burden, but after learning it, it was definitely content that was a big help. If I were to pick one thing that was a bit disappointing, in the test code part, rather than delicately writing for each layer, there were many methods that checked the entire functionality with @SpringBootTest, which made the test flow a bit confusing at times. However, considering that it was a course focused on feature implementation, it was fully understandable, and overall, it was a very satisfying time. It's almost disappointing because it feels like I only got a taste of a part of Kooke-nim's extensive development knowledge, and I will be eagerly waiting for the courses to be released in the future. Thank you so much for the great course! 🙇‍♂️
