This is a great lecture that explains things in a simple and easy-to-understand way.

Instructor Sun-guk Kim has an outstanding ability to pinpoint and deliver key concepts more effectively than other instructors. He conveys only the essential information without unnecessary explanations, making it easy to understand and highly effective for learning. I highly recommend his classes; once you listen to one, you will definitely end up taking his other courses as well.

This was very helpful in building foundational knowledge of Kafka. In some ways, I think this is the most suitable introductory lecture..! It was great for building basic knowledge of Kafka in a short amount of time😄👍 I think it would be best to take this course first before moving on to other Kafka lectures.

It was a great lecture for learning the basic concepts of Kafka.

This is a great, informative lecture for beginners! Thank you. However, the audio is clipping quite a bit, so my ears hurt a little ㅠㅠ Also, where can I find the lecture materials? I couldn't find them ㅠ

Good

It was great how you organized everything from Kafka's core concepts to brokers, topics, partition structures, Producer/Consumer, and offset management in a logical flow. In particular, the hands-on practice using Spring Kafka allowed me to personally verify message transmission/reception and consumer group operations, which was a huge help in understanding Kafka. This is an ideal introductory course for those who want to quickly apply Kafka in a professional setting.

It is one of the few lectures that are truly easy to follow and understand.

This is a highly recommended lecture because the explanation of the composition while drawing makes it very easy to understand. Highly recommended!

I had a vague fear that social login and OAuth2 would be as complex and vast as Spring Security, so I hadn't been able to touch them until now. However, through this lecture, I was able to clearly experience the sequence of request flows leading from the authorization code to the access token and finally to the user information. Furthermore, by writing code for both the frontend and backend, I was able to gain a solid understanding of the scope of responsibility for each area and the potential security issues. This lecture is concise yet dense regarding social login and JWT. Thank you for the high-quality lecture.
