I worked with activemq and rabbitmq but never with kafka, this really clears my mind, basics like these are important to me, now I can start digging for more extended info. Thanks
Thanks for this introduction to Kafka, it's simple and easy to understand the basics of this tool. I am ready to go deeper now. Update: I am updating my comment because it is worth mentioning that Zookeeper is no longer recommended for communication across Kafka clients.
@@mupenziii2097 ZK is still used in current Kafka version (3.x) alongside with KRaft, but starting from next version (4.x), only KRaft will be supported.
Glad you’re back! I’ve written a Spring boot app that reads from and writes to a topic and I’m not changing the app to also send to a postgreSQL as well.
@amigoscode Hello big boss :-) I have a question. at minute 46:30 you write a messageController with a constructor like "public MessageController(KafkaTemplate kafkaTemplate) {some code}". But it is useless : why don't you simply inject the spring bean like that : @Autowired KafkaTemplate kafkaTemplate ?
Constructor injection has a lot of advantages over field injection, in matters of testability, clear visibility of dependencies, null safety as it ensures that all necessary dependencies are available, and makes the code more flexible and maintainable. That is why I prefer the constructor injection over the annotation.
Hello Nelson, Great. I have enrolled myself in the microservices course! Just my 2 cents to support your efforts. Keep up the great work. Thank you for sharing your knowledge.
37: 38 Correct me if I'm wrong, but in order to Spring can discover and use the custom KafkaListenerContainerFactory you specified, by deafult the bean name must be as kafkaListenerContainerFactory (not factory), otherwise it won't be picked up by the application context and none of the specified serializers and deserializer for consumers will be applied, but default KafkaListenerContainerFactory instance with default SerDes instead.
AsAlamuAlaykum Amigoscode, I just wanted to comment to thank you for paving a way in the coding industry for muslims. You inspire me not just because of your work ethic but also balance with religion like in your DITL where you prayed Jummah. Also thanks for the courses I'm going through them because I wanna do A level computing 😅
@@urmattilek Second you. Theres no term like coding for muslims. Software engineering is a religion in itself which we religiously pray everyday. It's worse to put religion in everything.
I bet you have the M1 MacBook. Damn, the speed it sends those messages is astonishing! I followed your tutorial on my job laptop which is a pretty strong machine itself too, but it couldn't keep up with the MacBook lol
Can you do a video on Reactive Spring with Reactor? There's like 123 different operators for transforming/manipulating data, I'm drowning in complexity :(
Yo i feel you. I told myself i was going to read for an entire day before i touched anything. Learned so much today about KAFKA. If anyone is looking to hire a KAFKA engineer, reply to this message. Seven years of XP
Hello Neflson, you put every thing that i need in this tuto... just you are brillant!!! Thank you very much .. i am very fun of all your tutos .. Good Luck 💓💓💓💝💝
Hey Nelson, at minute 41:40, you said that if we have more than one instance/replica of the same application, these applications will read from the SAME partition. Are you sure about that? I'm pretty sure that if you want to scale the application you MUST implement partitions OTHERWISE the second instance of the application will stay without any log from the subscribed topic. Please give me a feedback about that! Thank you, Cezary B.
Thanks for the video, I really liked the course. I have a question, how did you make your console output in IntelliJ colored for Spring Boot server log output ? Thanks.
I have to mention somethings, If you are working on the windows machine then you have to install and configure the Gradle and Scala in order to build the Kafka project. It will give an error using Scala for the first time, that you need to build the project before running the scripts, and by the way you can run Bash Scripts from the Git Bash command line tool.
Hi Nelson. I would really want you to post some great content about websockets, because I think this topic is really interesting for almost every beginner. So would appreciate it!
hi nelson, glad to witness such an amazing concept of kafka by you.. thank you.. :) could be really helpful if you could explain how to prepare dynamic topic name in an api to communicate via multiple topics in real time env.. thanks again man.. :)
Salam, Nelson! I'd like to know which technologies I should learn in order to build a cloud-native application in Java. do you have the roadmap for building cloud-native application in Java?
Very good tutorial, thanks a lot muslim brother. I was wondered when you made request from intellij idea, I did not know that way to make requests, I always use postman)
Full Course Available here: amigoscode.com/p/microservices
See you there
Hi Nelson! I would love to get the full course, but I have a doubt. Will the course include the projet deployment on AWS, GC or Azure?
Hi Nelson .. what’s the discount code for this full course ?
Hey Nelson, I'm a big fan of your work.
Thank you Nelson, can you upload this course on udemy ?
@@brandonquintanillaquispe5455 I think not
Nelson your way of teaching and sharing knowledge is brilliant. You should be proud of yourself. Continue like this !!!
he's an idiot and has no idea what he's talking about, go read my comment above to know why

uhullll on the weekend I coded the entire course, looking forward to the last class!!! amigoscode you are a amigo to me!
This is the clearest description and illustration of what Kafka is and how it's structed thar I've seen yet. Thanks!!!!

I want to ask you bro can u give le ur email or something like that?
جزاك الله خيرا يا أخي الكريم! ما شاء الله، بارك الله فيك!
trying to find myself the solution to a project and here comes amigoscode to the rescue! ^^
Amazing course, rahmat !
Excellent tutorial for Spring Boot with Kafka. Thank you.
That's my guru🙏🏼 Thanks to great people like these that we are progressing so fast!

The video we’ve all been waiting for
Thorough explanation of the concepts as well as the application. Kudos !!

It's no different are you learning from muslim or other. The code is same.

this is really some very structured tutorial, thank you
Lot of thanks Nelson. You do great work.
THANK YOU SO MUCH FOR THIS, WE WOULD APPRECIATE MORE IF IT WAS ON GITHUB TOO
Amigoscode, many thx for this and all tutorials which you created for us, it's very important topic. thank you very much :)
Amazing video! Keep up the good work brother!
Long live brother, thanks for sharing your knowledge love from chennai , tamil nadu , India
Thanks for amazing tutorials!
What is that plugin with the cat on rainbow in the project loading/building scale?
I have to mention somethings,
If you are working on the windows machine then you have to install and configure the Gradle and Scala in order to build the Kafka project. It will give an error using Scala for the first time, that you need to build the project before running the scripts, and by the way you can run Bash Scripts from the Git Bash command line tool.
@Amigoscode, you are awesome ... :)
Thank you so much for this video! God bless you 😉
Walikom Asslam,
Wonderful Video bro, please keep it up!
hi Nelson,
Thanks for this video. What about unit and integration test of the producer and consumer, i'm struggling with that. Any advices ?
why not to make kafka setup (serializer, deserializer etc) via application.properties? why you need this boilerplate with maps and configs?
جزاك الله خيرا
Sooo pumped for this!!!
Just in time, thank you very much! Graphql + Spring Boot should be a good choice for a new video I think.
Hi, Great Video as always! Thank you.
hey public record not exist on java 11 is there replacement?
Hi Nelson. I would really want you to post some great content about websockets, because I think this topic is really interesting for almost every beginner. So would appreciate it!
Thank you for this tutorial. Really helpful.
@Amigoscode Is there any resources or teaching you've done that tests spring-kafka?
dude, why you are so good
Why didn't you use a Kafka docker container?
you are awesome brother, keep going!!
May Allah reward you for this job bro :)
Thanks for a beautiful explanation!!! You have the patience and power to teach us! Thanks again!
gracias por tus videos ..! you're the best😎
Can I conclude that kafka is analog of AWS SNS where rabbitMq is analog of SQS? Just more customizable and with richer functionality
So is there a way to secure the Kafka topic or broker for only users register in the API can consume data?
Fantastic tutorial
hi nelson, glad to witness such an amazing concept of kafka by you.. thank you.. :) could be really helpful if you could explain how to prepare dynamic topic name in an api to communicate via multiple topics in real time env.. thanks again man.. :)
Salam: I could not start zookeeper at minute around 14:35. It gives an error. Please help.
What is adventage in kafka configuration in the config classes opposit configuration in properties files?
Salam, Nelson!
I'd like to know which technologies I should learn in order to build a cloud-native application in Java.
do you have the roadmap for building cloud-native application in Java?
Thank you for these great videos.
Thank you very much for these videos, they are very helpful
at 43:05 - why you need to restart once more??? can you explain?
Thanks sir! This's really helpful for me
Please amigo can you do same microservices using Node js from scratch like the way you did for the spring boot
Amazing concept of Kafka.. Very well explained... thank you.. 🙂
great course!! thanks a ton:)
Looking forward to learn Kafka.
Amigo Thanks a lot. It was very well explained and in detail. Keep it up.
Great Stuff, Thanks for sharing
Hi Amigo, thanks for your videos.. really helpful.
Amigo, great Job!
Great tutorial, thanks!
what tool did you use for the slide? is it powerpoint?
Hi.. do you have plans to prepare some videos about apache camel? Maybe whole course about that technology? :D
Could you please make a video on jasperReport reporting with spring framework and Angular?
Thank you, that was great
Will you add cqrs,saga patterns to your microservice course?
Thanks for the new video, it helped me a lot.
I hope later you can make VueJS content with Spring Boot.
Best regards.
Do you have the 2024 version?
Does a partitioned topic live in the same node?
you said that kafka topic can keep the message forever, if we send two different messages to the same topic, it will only keep the last one right?
Very good tutorial, thanks a lot muslim brother. I was wondered when you made request from intellij idea, I did not know that way to make requests, I always use postman)
