✅ Redis tips from practitioners that appear here and there!

💡 Those preparing for DBA (Infrastructure Operations)!

💡 Those preparing to become backend developers!

💡 You've just been assigned to a project that uses Redis, but you don't know anything about it!

Q. Can non-majors also take the course?

So that even high school students can understand We will slowly organize and explain the knowledge necessary to understand the content.

Q. Is there a reason why you only practiced Node.js code?

This is because the pace of hands-on learning is faster than in Java, C#, etc. However, the logic can be applied as is to Spring (Java, Kotlin) or .Net (C#) development .

Q. Will I learn everything about Redis just by taking this course?

Because this course is a TypeScript course, the NestJS section doesn't cover the backend or code quality considerations. This section focuses solely on how to effectively use TypeScript in NestJS. To be honest, I can't say I fully understand everything, but I'm confident I understand about 80%. The remaining 10% is something that requires operational experience. (I believe the remaining 10% can be filled in by examining Redis's internal Rust and C code. I didn't add that because it would have made the course too heavy.)

Q. Don't you explain Redis Streams?

Redis Streams only handles two to three sectors, and in my experience, I haven't used it much in practice. Apache Kafka and Elastic Search are primarily used for specific purposes, so I boldly omitted them from the lecture.
