Realtime Datalake Using Kafka & Spark

It was a remarkably high-quality lecture.. Simply moving. Usually when taking lectures, you often face situations like 'Why isn't it working when I followed exactly?', and there would be quite a few such cases, but I completed this smoothly without any of that. When choosing a lecture, I first look at the curriculum and compare the price and duration. Until now, there have been many lectures that were too superficial compared to the price, But I guarantee that if you take Hyunjin's kafka&spark lecture, you can produce sufficiently high-quality results in future projects as well! I learned a lot. Thank you! (When do you think Season 2 will be released..?)

I'm learning so much from the curriculum and content that are organized far better than I expected. I really felt that you put a lot of care into creating this course. I'll be waiting for the follow-up courses. Thank you.

I trust and watch Teacher Hyeonjin's classes. Highly recommend. I discovered this through the Airflow course, and it has many differentiating factors from other courses. From concepts to architecture design, I liked how you explain the reasons for use and principles. The hands-on practice is comfort itself. You always provide kind answers as well. I'm still in the early stages of taking the course, but I'll complete it all~ The weather is hot, so please take good care of your health.

I haven't finished watching all the lectures yet, but just from the AWS environment configuration section, I can already guess the quality of the entire course.. Personally, even if you're not in the data field, this is a lecture that would be quite helpful for those working in architecture as well. I'll work hard to complete the entire course!!

It was incredibly helpful, and I dare say it's a perfect lecture!! Even though I have experience building with Kafka and Spark, there were quite a few parts I didn't understand during the build. You scratched all the itchy parts, just like a public bath scrubber. Your pronunciation was excellent, and the explanations you gave, pinpointing only the key points, were very easy to understand. Unlike lectures that are only theory, you made it possible to follow along with the practical exercises, and you told us in advance about potential problem areas, so I was able to do the exercises very comfortably. It's incomparable to other lectures without practical exercises; I understood many more parts by doing it myself, and I gained confidence that I could do it too. The quality of the lecture was excellent, to the extent that it can be used immediately in actual projects👍 I hope a follow-up lecture comes out soon, and I also plan to listen to the Airflow lecture filmed by 현진님! Thank you for the good material. You worked hard.

It's a perfect, excellent lecture. I'll also check Airflow when I have time! Also awaiting next lectures!

The detailed explanations made it easy to understand. The practical lectures were good.

Okay.
