[@brandonquintanillaquispe5455]

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?

[@czargaurav]

Hi Nelson .. what’s the discount code for this full course ?

[@DevMadeEasy]

Hey Nelson, I'm a big fan of your work.

[@atefjlassi193]

Thank you Nelson, can you upload this course on udemy ?

[@NitrosS]

@@brandonquintanillaquispe5455 I think not

[@NolteGameOver]

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

[@thodoristsoufis1253]

Nelson your way of teaching and sharing knowledge is brilliant. You should be proud of yourself. Continue like this !!!

[@CheeseStickzZ]

he's an idiot and has no idea what he's talking about, go read my comment above to know why

[@pedro.carara]

uhullll on the weekend I coded the entire course, looking forward to the last class!!! amigoscode you are a amigo to me!

[@anassabrd112]

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]

Hello, what would you recommend now instead of zookeeper?

[@anassabrd112]

@@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.

[@ian0m]

This is the clearest description and illustration of what Kafka is and how it's structed thar I've seen yet. Thanks!!!!

trying to find myself the solution to a project and here comes amigoscode to the rescue! ^^

[@FranciscoQuintero-em7tr]

Absoluty ... the java goat in YT content. thanks

[@SamriBliss]

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.

[@abdellahlakhnigue3086]

I want to ask you bro can u give le ur email or something like that?

[@hoki8296]

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!

[@azizbekibnhamid642]

Amazing course, rahmat !

[@ayxxn4931]

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]

But you don't need religion to study. It's no different are you learning from muslim or other. The code is same.

[@ayxxn4931]

@@urmattilek Never said its not, that's not the point I'm making

[@swarupcodes]

@@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.

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.

[@alexluke_again]

love your content. you're so calm and a wonderful presenter. best of luck

[@himanshubhusanrath212]

Thorough explanation of the concepts as well as the application. Kudos !!

[@DevMadeEasy]

Hey Amigoscode, Great Content as Always!✨ Thanks for Sharing it!🙏🏻 You Have Been an Inspiration for My Own 📺KZbin Channel!!!

[@sanatbek819]

Hope your community will be 1 mln soon, InshaAllah brother!

[@devguyahnaf]

Nelson is giving so much of this course away for free. I just love it!!!

[@theclam1338]

The video we’ve all been waiting for

[@kluch46]

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.

[@valentinpopescu6704]

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

[@abdurrehmankhalid2290]

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.

[@andres98]

Congrats for a really self-explanatory video!

[@eddylequartier]

@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 ?

[@anassabrd112]

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.

[@python2448]

I'm so glad, the youtube recommended me this video. 👏

[@iReflections]

Long live brother, thanks for sharing your knowledge love from chennai , tamil nadu , India

your are one of the best teach i've follow

[@brandonstivenrodriguezalda6300]

Excellent video about Kafka and its implementation

[@jnayehsirine6222]

a friendly reminder :i will appreciate if you start with explaining the code rather than reading the code along . thanks for the free content

[@qwertyguy7750]

Nelson is a legend, that’s it!

[@segfal]

I love that you made this, i was looking everywhere for this!

[@andyescobar202]

🎉 That tutorial was perfect.

[@abdaziznet]

hey public record not exist on java 11 is there replacement?

[@_skeptik]

this is really some very structured tutorial, thank you

[@skazijp]

how happy i am seing great muslim software engineer, thanks for the content

[@thatoneuser8600]

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 :(

[@mohammadziakhan5693]

I do understand your pain

[@03greedo29]

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

[@akyjlehok5843]

What is that plugin with the cat on rainbow in the project loading/building scale?

[@ilyababcenco6864]

Just in time, thank you very much! Graphql + Spring Boot should be a good choice for a new video I think.

[@ArjunKumar-zu2kl]

Just wow, Amigo, Thank you so much :)

[@marouaniAymen]

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.

[@akyjlehok5843]

What is adventage in kafka configuration in the config classes opposit configuration in properties files?

[@nikitazinchenko2561]

Amigoscode, many thx for this and all tutorials which you created for us, it's very important topic. thank you very much :)

[@cisinojunior3327]

Why didn't you use a Kafka docker container?

[@TheDestoy123]

Do you have the 2024 version?

[@oficialreinaldoneves]

You are my hero man. Thank you so much for this content.

[@cezarybek6679]

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.

[@Hemant._.Dhiman]

I am having the same doubt!

[@LPS-ln1mz]

why not to make kafka setup (serializer, deserializer etc) via application.properties? why you need this boilerplate with maps and configs?

[@ahmedelmawrdy4381]

Walikom Asslam, Wonderful Video bro, please keep it up!

[@hamidoubalde2517]

Lot of thanks Nelson. You do great work.

[@halcyon-s]

[@telefonmakinesi6467]

Can u do that with string and object

[@robertoenriquechavezrodrig731]

Thank you so much for this video! God bless you 😉

[@TheBhabanisankar]

@Amigoscode, you are awesome ... :)

[@alandecunto753]

So is there a way to secure the Kafka topic or broker for only users register in the API can consume data?

[@thalibmuhammad9519]

dude, why you are so good

[@loandao1996]

Thanks sir! This's really helpful for me

[@omarlamrabet379]

May Allah reward you for this job bro :)

[@sarahemmati2057]

Hi, Great Video as always! Thank you.

[@JSneider05]

Looking forward to learn Kafka.

[@achraftaffah4458]

Could you please show me how to draw a technical architecture like the one you used in this tutorial?

[@Release1234]

@Amigoscode Is there any resources or teaching you've done that tests spring-kafka?

[@mariumbegum7325]

Fantastic tutorial

[@011ayush]

Thank you for this tutorial. Really helpful.

[@ivanlorenzo04]

Bruuhh, how did you know I was looking at this tutorial!?

[@ijasahamed1323]

Noticed that smashing like button became 2 seconds to 1 second 😁🙌

[@susydev3722]

Thanks for the new video, it helped me a lot. I hope later you can make VueJS content with Spring Boot. Best regards.

[@Netalon]

Can i retain messages published on a topic ? If yes, can I delete them later ?

[@edwinangar]

Hi. In the amigoscode page the kafka chapter No 9 and 10 are mixed, I was lost at the beginning 😂😂

[@shermatovs]

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!

[@aditikaushik5147]

Amazing concept of Kafka.. Very well explained... thank you.. 🙂

[@muditjain9117]

Amazing video. Any chance of getting a link to git repo of the code in the video?

[@jibink7969]

you are awesome brother, keep going!!

[@magdalysantos3848]

gracias por tus videos ..! you're the best😎

[@adityasrivastava5322]

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.. :)

[@testmyplaylist]

Hi Amigo, thanks for your videos.. really helpful.

[@IbrahimB-yc2zt]

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?

[@martindouglas-p8e]

hi Nelson, Thanks for this video. What about unit and integration test of the producer and consumer, i'm struggling with that. Any advices ?

[@vjotov]

at 43:05 - why you need to restart once more??? can you explain?

[@Najish101]

Does a partitioned topic live in the same node?

[@MrMarquinho22]

Thank you, that was great

[@renz82]

what tool did you use for the slide? is it powerpoint?
