this actually isn't great work because he said it's not good for anything besides key-value pairs & used as a cache. Redis works great as a primary database and RedisJSON + RediSearch can easily make Redis a relational/primary database. Redis is more than a simple cache. It can and does replace SQL as primary database.
Amazing video as always.But here is 1 important thing that maybe is not clear for everyone. Redis is an in-memory but persistent on disk database, so it represents a different trade off where very high write and read speed is achieved with the limitation of data sets that can't be larger than memory. Which means it's not like it's being stored only in memory and is not persistent. It stores everything in memory and write on disk is optional but still there for use.
Awesome video, going through their docs I was confused on how it would be used in a real world app but your demonstration with the photos app and your postman clone was killer. Good work!
Hey Kyle, In addition to course of languages like css,js,react (which are most available) Please do a course on the real world web dev topics like redis, kubernetes, testing, jenkins etc.. would love to buy a course with such content
I have been watching a long time, I enjoy your videos, instructive and short and explained! Thank you Kyle I hope there is someone in the field of VoIP or RTC like explaining things like this.
Regarding nested hastes. Redis doesn't natively support nested data structures. However, you can serialize your data into a format like JSON before storing it in Redis, and then deserialize it when retrieving.
Another easy way to work with Redis on any OS is Docker. Just create a Redis container and use that. When you are finished with it you can delete the container. Then you don't have to worry about random services running on your workstation.
The first time you request something actually got slower because it takes time to write the response to the cache. It would be better to first respond to the client, and then write to the cache.
There's one tricky thing to keep in mind about this. Your Redis server is running on your local machine, and the actual API is somewhere on the internet. It's OK for me to say that redis is faster than a regular uncached API call through the internet (probably), but in my opinion, this comparison is not legit. It's kind of comparing ordering a pizza vs having a pizza already. To have a more realistic idea of the timing, if timing matters, a cloud hosted redis service should have been used. I'm pretty sure that this strategy starts to make real sense under high request volume scenarios. Anyway, I got the idea and I learnt a few new concepts, so thank you, mate!
Very informative. 18:39 For maximum performance, you really wouldn't want to parse any data that is already in the Redis cache, but return it as is to the client over the wire, because HTTP responses are strings anyway. I'd call this a bug.
WTF. U have 6th sense . I was searching about your video on this new topic I found today but I couldn’t find it . But within few hours you posted it . Awesome .
Please, before adding redis to your stack, make sure there is nothing else that you can do instead. When your database takes >100ms to return data, there is most likely a problem with the database schema (like a missing index or you have a bad written query). Just adding a redis cache doesn't solve the underlying problem, it just makes the symptoms less bad.
remote databases (like most node developers use Mongo or similar free-tier service) will usually take 100+ms to return data. onprem databases really shouldn't take anywhere that long to return data unless you are doing complex join operations
This is pretty badass, I'm a full stack developer but my path has not crossed Redis yet and I've been wondering for years now when it would happen. I've been waiting for the dreadful day that I had to use it and figure it out with the documentation on the fly.
Awsome vid Kyle, could you do a video on using Redis as a cache layer and using Drizzle ORM with PostgreSQL. I really love the practical example using Node.js at the end. Would love to see some more on this like a leaderboard implementation, chat feature etc. Thanks Kyle!
You can run Redis on Windows. 1. option is install a service for it (you can find it on Google) or 2. option Laragon local PHP/WP environment has it built-in too. Otherwise thanks for very insightful video.
kyle: while ago posted a video titled "why i don't care about performance" kyle again: learn Redis to improve performance xD sorry if i wrote your name wrong amazing video as always :D EDIT: lol while watching the vid i see your name and it correct
tysm, now I can add 3 years of experience with Redis to my resume
If you watch it a second time does it become 6 years experience? Mr. G from HR

@@minnesnowtan9970 No because it is already cached

Great work! Couldn't have explained it better! - Justin

He makes it so easy. Shows the amount of work he has put in to show us what's necessary.
Gold. Working in a remote company since 4 months and still learning from your videos. LEGEND.
Would really love a POSTGRES crash course...Nice one Kyle
literally the same as mysql

Dude please a Postgres tut would be great
but he made his own

I love the direction this channel has taken in the last weeks. Keep going with these practical and detailed videos Kyle! Thanks for your hard work!

I can bet all my money into this channel. This guy is so hard working! #inspiration
Let's get him listed on one of our stock exchanges 😅😂😂
I agree. Kyle is one of the best
One of the finest tutorial of redis I witness
Best explaination for redis basics and implementation so far, great job Kyle.
This guys is really great...He helped me during sem exams, placement exams...now in professional life(work) too.
Kyle I never used Redis before and didn't know it was that easy to implement, really simplified thanks.
Elasticsearch tutorial would be great. Your videos are great. Simple, direct and quick. Perfect! Thanks
I love this redis tutorial. especially the helper function part where you set and get keys.
Less than 1:30 mins in, I finally understand what Redis is. Great video!
A Elasticsearch tutorial would be great.
Thank you for your hard work.

This video was amazing. Simple straight forward! I already loved your video, but this one impressed me. Excellent job.
Best Redis video on the Internet!
Before this video I only knew that the redis is used for cashing data, But now I know how and where to use redis, Thanks kyle
Kyle - you have explained a difficult concept in simple terms and demo with live working code. Thanks a million.
This is by far the best Redis tutorial
Absolutely amazing video, straight to the point, fast and clear, loved it

Correct, Thats ‘Utility Container’.
Thank you Kyle. I understood it in one go. The explanation was perfect. Keep up the good work. Thank you again :)
First 3 minutes of this video are pure gold
0 to something in redis in just 30 mins. Great work man.
You said "Redis" so many times that after finishing the video I can still hear "Redis" 😹 but thanks for the awesome resourceful video.

You are awesome, I've been struggling to learn Redis for months!
The first time you request something actually got slower because it takes time to write the response to the cache. It would be better to first respond to the client, and then write to the cache.
Awesome video. Clearly explains everything you need to know about redis.
Thanks, Kyle it's the best redis course I have ever seen 💛.
Thanks for this course! 13 min 101 tutorial + real-world example!
The working example made it very easy to understand. Thank you
Yisus man, that explanation was amazing! this is true learning way! thinks that learn pretty quick are awesome!

I am new to redis and you made it so simple totally loved it🔥🔥 thanks Kyle😎
I sped up this video and learned redis in 15 minutes.
I just learned that redis is an implementation of what we call as memoization.
Thanks :)

🔸Wow Kyle this is the best Redis Tutorial out here. Great job man... Keep up the excellent work. 👍
Clicked on another tutorial but the accent was killing me. Thank you 🙏🏻
Another great video, Kyle. Many thanks
This was absolutely wonderful.
Short and sweet, well done!
Insanely good intro, thanks man
Hey Kyle, you are one of the reason which I've become NodeJS developer. Thank you so much ❤️.
where do you live? and is node.js is in demand in your country?? thank you
@@guyfawkes6930 I'm in India, yes node jobs are demand here.
So simplifide and clean code dude!

it helps when when working with external APIs which loading speeds you can't practically do anything about since you don't have access to them
this really helps me understand redis, thank you!
it was fabulous intro to redis.. thank you very much
