Bro - only infinite loop can be used to thank you. I cleared few interviews just with help of your Microservices playlist. You are simply awesome 😁
Thanks Karthik . Keep learning 😃
Sir we need kafka in depth please
I am continuing on it Tammam
while(i < 1000) { System.out.println("Thank you"); i ++;} 😍
Stunning tutorial for understanding the reactive programming, unblocking, asynchronous concepts in Spring boot environment. BRILLIANT!
I thought you will upload parts like other are doing for more number of views, Thanks bro for your effort. You are giving valuable stuff free of cost. 😍
Thanks Sree 😀
@@Javatechie in my CTS office team for the new commers I will tell them to watch your videos🙂
You are a life saver. May your knowledge and wisdom increase as you keep giving to the world.💪
I am really short of words to thank you enough for what you have shared here. Really really appreciate your simple and steady flow of explaining the concepts along with the application development. This is one of the best explanations I have ever come across. You are going to shine brighter with each passing day.
Keep helping everyone by sharing your knowledge like this. Thank you again :)
Thank you so much buddy keep learning 😊
You are a great teacher. Keep up the good work. You are amazing.
Thank you very much ! Very helpful for understanding reactive programing and use of Mono and Flux..
awsome video bro!
Just something to complete: thoses who have a whitelabel error when calling reactive endpoint,
if both spring mvc and spring webflux running together you have to add "spring.main.web-application-type=reactive" in the application.properties file... By default, mvc could overtake webflux.
Thank you so much for covering all important topics ...very well explained ..big thanks cant thank u enough
Great tutorial, Great Teacher .
Thank you 😊
Thank you! Your tutorials are really great!
this is frigging amazing. best one i have seen.
i used to follow you even it 2-3 hrs vedio also because perfect explanation on what topic you want share with us.. i like your
perfection bro..
Way you explain the things, its commendable. Keep up doing the good work. #javatechie❤️
Great content and clear explanation. Appreciated for the video.
Thanks for this one, really deep and clear. I was expecting towards the end you would replace the RestController with Functions. It would be great to see that. Especially a use case where you need to return a Flux from a service method and you are passing some filters via the DTO inside ServerRequest.
Thank YOU.. It was very good with lot of details for new BEE to REACTIVE 👏👏
Great class! Thank you so much ❤
I would like to see an implementation using Java 11 and at least Spring 2.6.2. Also use a broker like Apache Kafka, or rabbitMQ publishing and consuming from the broker. Thanks. Great content. 👍
Great tutorial, Well Explained. Thanks for your effort.
Learned new things from your channel. Thank you for the efforts.

I appreciate your time n effort bro you are helping a lot to understand the concept. I regularly watch your videos to understand basis and more.. Thanks a lot...
Keep learning buddy thanks
Congratulations, this content was very good.
I was in hesitation to start learning reactive. But just tried one sample video. Then I looked for the whole c2 hrs video. It's simply superb. The need , why. How when to use reactive you explained is just awesome thanks a lot. One more topic I can add to my resume now
On stop Solutions for all Java and spring related knowledge ❤️
Excellent
Great explanation!
Very very helpful. Thanks
Thanks alot for this content.
#JavaTechie Rocks!!!
You can search on whole TH-cam and google, I bet you cannot get this kind of unique content anywhere.

Awesome man. Keep it up. You cannot even imagine how much great help you are doing for IT people.
Thank you so much chetanm for appreciating it . Keep learning 🤞
Thank you so much for making such a helpful videos..🙂🙂
Bro, you deserve 💐👌, very well explained
Back pressure on data Streams- kindly give an example. I watched the whole series took notes. It’s very lucid and very well demonstrated. Thanks.
Great!
I just want to say. Thank You.
@Javatechie you are awesome
Very nice.. Thank you
In morning, I was thinking that I have learned traditional method now I should start learning Reactive programming and now you have uploaded the video. What a coincidence 😁
Cool 😀. keep learning
That's great, thanks
Very useful tutorial thanks
Really nice videos.
Very helpful
You are giving your best knowledge. I got my job because of you
Glad to know this Vishal keep learning 😊
Good tutorial
thanks for the wonderful course. I have another requirement where i just need to send an event whenever new records get inserted into the DB. Currently i can see Flux can continuously emitting the events(with Delay method) , which i don't need , it should only be publish when new item gets inserted. Can this somehow be achieved by WebFlux
Great video and simple explanation.
Only one observation, for update and delete APIs, verbs "update" and "delete" should be avoided in REST as per the best practices.
Thank you.
Agree 👍
Thanks for sharing this Knowledge full video, but I have one small doubt, what is the difference between the
Normal Controller -> service implementation and Router -> Handler Implementation.
is there any specific technical difference ?
Kindly help me here.
Thanks in advance.

Thanks thanks thanks bro
Hey Basant, Although unrelated to this video..Can you make tutorials of implementing kafka using vertx?
Awesome video.
Could you please provide some insights on how to deal with race conditions in reactive programming
Okay great I will cover one scenario for it
can you plz tell me the difference between flatMap, map interms of java 1.8 and reactive(reactor core) programming?
Hi. I try to using r2dbc to connect to mySQL db. But i got some errors. So i would like to know, currently, we can connect to mySQL by using r2dbc or not. I using r2dbc because i want to manage transaction by reactive transaction.
Asynchronous programming doesn't necessarily employ an Event Loop. Event Loop is the way how JS achieves non blocking asynchronous model.
I faced when run in saveProduct inside controller. when I change from Mono into ProductDTO , its run well. How could be I face that error ? any suggestion ? thanks
More videos on webflux please
why you are not using "produces = MediaType.TEXT_EVENT_STREAM_VALUE" in the second part of the video the crud implementation with mongo db, in the way you implemented we are keeping synchronous and blocking?
How can we implement entity relationship ? Is in reactive programming achieve this ? Thanks
Just curious about how much time is being saved or how many orders more are processing. One question that was not clarified was "Can the cook work on more than one order at the same time?" If s/he can only work on one at a time, the the cook will be like a bottleneck and taking more orders may not help a lot more as the orders will be just sitting there and the throughput will be limited to how many orders can the cook complete per unit time.
Sir can you please also do some video on akka and spring
Question: Why in the second example MediaType was not required in controller?
Hello World wake up, Basant from Java Techie has uploaded another video, thanks bro!
Thanks bro 😊
😍😍😍😍
Hi Brother, First of all its a great tutorial to start working with reactive programming and bro could you please add two more module like reactor kafka and rabbitmq?
Okay i will
Fantastic tutorial, Very well organised, the initial theory section was in perfect detail to get started, I am going to watch the last hour. Just one question, what if I have mostly a traditional Web application, but I only need a few reactive end points for server sent events, and/or web soockets, would it be better to create a whole new application running on another server like this or would it be better to mix these two if this is possible/advised ?
Is it better to use Web flux and then send normal responses or the other way around ?
Thanks buddy for appreciating it . Yes it's always good to have a separate repo to deal with reactive projects we can't mix them
@@Javatechie Thank you for getting back to me. Just one last question if I may please. What are your thoughts on Quarkus vs This or Spring Boot MVC ?
Since Quarkus has both in the same server I think ?
@@peshutanpavri1599 to be very honest i haven't explored more on quarks will do one benchmarking and update buddy ☺️
Love the way you teach 💚
Btw could you let us know which laptop do you use ?
HP pavilion
What's the advantage of using router-handler way as opposed to the traditional web-controller-service convention?
It's just a functional style of coding
Why should we use spring reactive framework when Java provides completable future and spring provide @Async ?
Great content sir . One quick question can we use Record in place of ProductDto as a referrence ?
Ofcourse we can buddy
Hello. Can you please try to do a series on REACTJS @javatechie
Many thanks, Java Techie for this great content. Really appreciated!!!
I have a question though: how would it be possible to design a real-time notification using reactive programming? Let's imagine two users of your API playing a scenario from different UI components (one adding, and the other one listing the products). My question is to know how to do it in a way that the first UI (GET /products) opens an HTTP stream channel and receives the newly added or updated products once these ones get inserted into the DB.
@Vibhor Mittal still waiting for the reply from @JavaTechie
I didn't understand your question properly could you please elaborate bit more or drop me an email javatechie4u@gmail.com
Please do share the answer here if received from Java Techie. It would be useful for all the viewers. Thanks in advance.
@@Javatechie I will drop you an email.
Thanks for your time and effort
I will check and update you
Can u please make a video for micronaut with reactive programming and apache kafka combination
Can you please upload the same crud application with Mybatis.
1:48.00 why didn't you use normal object instead of mono of request body object
Hi Bro,
Amazing tutorial!! I have a query here - followed the same approach as mentioned, but when I load the url in safari browser the reactive part did not work, it waited until it reached 10 and only then the data was displayed in the page (same case as Traditional rest call), while in chrome browser it worked fine. Can you please let us know if there its a browser issue or configuration issue
Not sure if the browser behaves differently .
Can you explain where this method is implemented? ```Flux findByPriceBetween(Range priceRange);```
I could not find it in the ReactiveMongoRepository.
Please try to understand features of spring data and it's syntax
In case you have not been adequately informed, please consider this official notification that you are awesome.
Hey, thank you for the tutorial dude, really appreciate it. I've got something to ask. On the Repository, we have findByPriceBetween(), the question is how does it actually implement the get elements between the range since we didn't implement the function? Seems like we just call the non implemented function and the repository know how to find the element between the range.
Thank you.
This syntax came from JPA findBy always prefix and between is operator
@@Javatechie Ah I see, thank you so much
57:08
If someone is getting the option to save the file, just try to open the URL in chrome browser. It will work there.
My question to creator is:
Is there any reason why it is not working in Firefox?
When are you uploading React tutorial first video ???
wanted to play with reactive programming... I've 3.5 yrs exp in java & spring related stuff. I will work on spring webflux soon. should i directly learn reactor or go with rxjava first and then reactor? any opinion?
You can directly Learn from this
I thought Reactor is used by Spring? And to me, RxJava and Reactor are the same in concept. Singles in RxJava are Monos in Reactor, and Observables in RxJava are Flux in Reactor. They both have the same operators as well
18:12 onNext method provides the partitioned data or each request’s data.?
Each request data
thank you for the clarification
