I had watched many videos from different KZbin channel about reactive program ing.but from your video...I got to know what actually reactive programming is...keep up the good work👍

[@tomchandler2356]

Amazing work! I've been trying to understand this topic for 2 months now. Kudos👍👍

Great way of explaining Async & Non- Blocking. I have knowledge of Node.JS Async & Non-Blocking. But the way you explain this is awesome. Loved it !!!

[@Javatechie]

Thanks buddy 😊

Wowww... Simply Ossome. Thanks Basant. Very clear and informative (y). Waiting for next video.

very nice video, you're the best man

[@natetolbert3671]

Great vids! Thank You! Also, to maybe save you a little time in the future, I have a tip. Any time your entity has no final fields (and no @NonNull), your @Data will automatically create a no args constructor, so no need to write it out.

Great content and easy to understand way. I have a question related to map function used in method getCustomersStream : .map(i -> new Customer(i, "customer" + i)) . As per documentation it says ,asynchronous Thanks

[@DeepakPandey-ij3bz]

Thanks for the informative video. I have one query, as you have used event stream media type and it started to push single record on the browser without using the event stream media type there was no difference between the reactive and non reactive end points. Event stream is kind of server side events, should we always use the event stream media type whenever we are using reactive programing? Please suggest

[@StyleTrick]

Great video! The downside of reactive programming is that the whole application must be reactive, including the database and everything else. The majority of JDBC drivers are blocking and is a reason why I predominantly choose to design my applications without the use of reactive programming.

[@kameshganeshan2894]

blocking/non-blocking depends upon your application requirement. if you are working with a transactional context in fintech, then there is no use and everything has to be atomic.

[@StyleTrick]

@@kameshganeshan2894 That depends on the context, Fintech ranges from transactional payments to high throughput messaging. Non blocking architecture tends to scale much better in terms of the latter.

[@kameshganeshan2894]

@@StyleTrick I agree, I should have phrased it better.

Hi , i have small doubt y data not populated on browser , since in traditional approach Request/thread concept as soon as we get response for first thread it shud immediately populate on browser why are we waiting till all threads response ?????

21:05 Good job. And that ladies and gentlemen is a demonstration of webflux or “flow”. Data flows as it becomes ready. This Spring project would have been called webflow but there is already a Spring project called Spring Webflow, thus it became webflux.
