Introduction to Redis for Non-Majors: From Basics to Practice (Query Performance Optimization Edition)

Announcement (25.08.11.)

Hello! This is Jaesung Park from JSCODE :)

After taking the Redis course, from the perspective of some students,

It seems there are often cases where people end up disappointed because it differs from what they expected 😭

In the hope that fewer people will be disappointed by the course,

Before purchasing the lecture, so that you can make a wise purchase,

I have summarized and posted some points that would be helpful for you to check!

1. Structure of this course
   This course is not a deep dive into the conceptual depths of Redis. It focuses primarily on the basic usage of Redis and how to apply and deploy it in real-world projects. It also includes a process of verifying whether performance has actually improved through load testing after applying Redis.
   
   Since the content you expect might not be included in this course, I highly recommend checking the curriculum before purchasing!
   
   (Next time, I will create an additional course focused on Redis so that you can learn in-depth concepts and advanced applications! 😭😭)

   
   

   
   

2. Lecture Duration

   
   This course is relatively short, with a 3-hour duration, compared to other courses I have created.

   
   
   

3. Price Adjustment
   I believe the price for this course has been set too high relative to its length. Therefore, for those purchasing from now on, please use the link below to receive a 30% discount coupon!

I will put more care into the upcoming lectures.

lectures that can satisfy as many students as possible

I will do my best to create it!

Thank you.

Sincerely, Jaesung Park from JSCODE.

🤬 Forget it, I can't do this anymore!

My name is Jaeseong Park, and I started my career in development as a non-major, served as a CTO at several companies, and am currently active as an educator. I also had a time when I started development as a non-major and studied Redis.

When I first tried to study Redis, I felt overwhelmed and didn't know where to start. This was because most books and lectures simply explained Redis data structures (string, list, hash, set, sorted set, etc.) and endlessly listed countless commands (SET, GET, EXISTS, DEL, HSET, etc.). As a result, the question "When will I ever learn all of this, and how do I actually use it in practice?" never left my mind.

I somehow managed to introduce Redis with the goal of improving performance. While it definitely seemed faster, I was left wondering how to test exactly how much faster it had become and whether I had implemented it correctly. As a result, I lacked the confidence to actually apply it to a real-world project.

Since I also went through a time of such anxiety and difficulty, I decided to create a Redis course that even non-majors can immediately apply in practice.

✨ 4 Key Points I Focused on While Creating This Course

👍 This course is recommended for the following people!

🙊 What will you achieve after completing this course?

✔ Notes

The course proceeds on the assumption that you have a basic knowledge of Spring Boot. Therefore, I recommend taking this course after learning basic Spring Boot. However, even if you are not familiar with Spring Boot, you will be able to learn effectively by utilizing the 'Comment Study Method' that I will explain in the lecture. If there is anything you don't understand while studying, please ask immediately using the Q&A board or the 1:1 open chat room😊

🚨 Be sure to check who the educator is!

If you meet the wrong doctor, you may face death because your illness cannot be cured at that moment. However, death ends with the pain of that moment. But if you meet the wrong teacher and receive the wrong education, you will suffer for the rest of your life.

Due to wrong education, you may end up at a company you don't want, receive a smaller salary than expected, and live in pain for the rest of your life because of it. Not only that, but the wrong education you received can even be passed down to your children.

I believe that education can truly change a person's life for the better, but on the other hand, it can also completely ruin a person's life. That is why I believe education carries such a heavy responsibility.

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

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

Hello!

I started studying development as a non-major. Somehow, I've already become a developer in my 6th year! Recently, I served as CTO at two companies while working as a developer. Whenever I had spare time, I've been doing coding lectures, corporate development consulting, and speaking engagements.

The number of students I have taught has already exceeded 24,000 (as of July '25)! As I feel every time I teach my students, I can never forget the sense of fulfillment that comes from education, so I plan to continue providing courses on Inflearn.
(* Produced successful applicants for Kakao Pay, Yanolja, and Woowa Bros among students)

Just as I received much help when I was going through difficult and challenging times, I wanted to become someone who could also help many others. Furthermore, I felt the greatest sense of pride and happiness when the value created through development had a positive impact on others.

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

Thank you!
