Redis Introduction/Practice for Non-Technical People (Query Performance Optimization Edition)

Notice (25.08.11.)

Hello! This is Park Jae-sung from JSCODE :)

From the perspective of some students after taking the Redis course,

It seems that there are cases where people are disappointed because it differs from their expectations 😭

In hopes that fewer people will be disappointed by the course

so you can make an informed purchase decision, before buying the course

I've organized and posted some content that would be good to check before purchasing the course!

1. Course Structure
   This course is not an in-depth exploration of Redis concepts. This course focuses on the basic usage of Redis, and concentrates on how to apply and deploy Redis in actual projects. It also includes a process of verifying whether performance actually improves when Redis is applied through load testing.
   
   Since the content you're expecting may not be included in this course, I strongly recommend checking the curriculum before purchasing!
   
   (Next time, I'll create an additional course focused on Redis, so you can learn in-depth concepts and application methods of Redis! 😭😭)

   
   

   
   

2. Course Duration

   
   This course is relatively short at 3 hours compared to other courses I've created.

   
   
   

3. Price Adjustment
   I believe this course is priced too high relative to its content length. Therefore, those purchasing from now on should use the link below to receive a 30% discount coupon when making your purchase!

I will put more effort and care into the lectures that come out after this

a course that can satisfy as many students as possible

I will work hard to create lectures that can satisfy as many students as possible!

Thank you.

🤬 Ugh, I can't do this anymore!

I'm Park Jae-sung, who started development as a non-major and worked as CTO at various companies, and am currently working as an educator. I also started development as a non-major and had a time when I was studying Redis.

When I first tried to study Redis, I was at a loss about where to start. That's because most books and courses would explain Redis data structures (string, list, hash, Set, sorted Set, etc.) and then just endlessly go on and on explaining countless commands (SET, GET, EXISTS, DEL, HSET, etc.). So the question "When am I going to learn all this stuff and how do I actually use it in real-world situations?" just wouldn't leave my mind.

I somehow thought 'I should try improving performance using Redis' and introduced Redis. It seemed like the speed had improved, but I wondered how much faster it actually got, how I should test it, and whether I had implemented it correctly. As a result, I lacked confidence in applying it to actual projects.

Having gone through such anxiety and difficulties myself, I thought I should create a Redis course that even non-majors could readily apply in real-world situations.

✨ 4 Points I Focused on While Creating This Course

👍 This course is perfect for:

✔ Reference Notes

The course proceeds under the assumption that you have basic knowledge of Spring Boot. Therefore, I recommend taking this course after learning basic Spring Boot. However, even if you're not familiar with Spring Boot, you'll be able to learn sufficiently by utilizing the 'comment study method' that will be explained in the course. If you come across any parts you don't understand while studying, please feel free to ask questions right away using the Q&A board or 1:1 open chat😊

🚨 Make sure to check who is providing the education!

If you meet the wrong doctor, you could die from not being able to cure your illness at that moment. However, death ends with that moment's suffering. But if you meet the wrong teacher and receive poor education, you will suffer throughout your entire life.

Due to wrong education, you may end up at an unwanted company, receive a smaller salary than expected, and suffer throughout your entire life as a result. Not only that, but the wrong education you received gets passed down to your children as well.

I believe that education can truly change a person's life in a positive way, but on the other hand, it can also completely ruin a person's life. That's how much I think education carries a heavy responsibility.

Therefore, please check who is providing the education, what kind of person they are, what path they have walked, and make a careful judgment.

👋 Hello!
I'm finally introducing myself ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

Hello!

I started studying development as someone from a non-technical background. Before I knew it, I've become a developer with 6 years of experience! Recently, I worked as a developer while serving as CTO at 2 companies. Whenever I had time, I've been doing coding lectures, company development consulting, and giving talks.

The number of students I've taught has now exceeded 24,000 (as of July 2025)! Every time I teach my students, I feel it again - I can't forget the sense of fulfillment from education, so I plan to continue teaching consistently on Inflearn.
(* Among students, successful admissions to Kakao Pay, Yanolja, and Woowa Brothers)

Just as I received a lot of help when I was going through difficult and challenging times, I wanted to become someone who could help many other people. And I felt most proud and happy when the value I created through development had a positive impact on others.

For these reasons, I hope that by sharing and giving what I've worked hard to achieve, those people can live a slightly better life.

Thank you!
