Thanks !

[@mastervn5463]

You are the best Java instructor I've known. Thank you for all the videos!

[@erikbustos2187]

Excellent, thank you for this great learning experience!

[@subhamkotal9975]

Very excellent course, thank you so much!!

[@IIEPEDO3]

Cool explanation. Thank you!

[@HighlifeC]

That confident 1,2,3,4,5... boom..Kaushik.... Thanks buddy

[@maitreymehta1359]

Thanks for this course.

[@siddheshlatkar2165]

Great tutorial. Thanks

[@gemkhatry]

Thank You @Java Brains.

[@jbird5892]

Great course, thank you. I am trying to prove that the reactive spring controller is more efficient. So what I have is a spring application with two GET endpoints. One returns String and the other Mono both endpoints call a method that creates a Mono with a 300 ms delay added. If I use a tool like k6 to load test each endpoint the results are basically the same as far as requests/second and average request time. So how can I prove that the reactive endpoint uses less memory or fewer threads etc?

[@saiprasadchindam5185]

Thanks for videos

[@shivask5543]

👌!! Thanks!!

[@virupakshak4746]

Hi Koushik Thanks for regular useful videos. Can we return ResponseEntity also?

[@Kopetefish]

I believe it would be Mono instead because the function should return a Mono

[@avdhootjadhav6705]

well aint that format like observed in Mono for method return type. So we can replace all return type with Mono in webflux. this is what I assume from observed patterns

[@vengateshm2122]

Can you explain how thread limit is handled in reactive app? Normal spring boot app has a limit of 200 which is 1 thread per request model. Can we exceed max thread limit in reactive app?

[@sonnysjon]

Hi Koushik, you mention in the video that you covered Mono.zipWith(), but I don't recall that from your previous videos in the series. Which video # did you cover that, please? Really enjoying your videos, btw.

[@updownftw_]

He didn’t specifically covered that, he just showed Code snippets of it. 1 in the beginning guess and one some 3/4 videos back

Koushik which fonts you're using

[@alexwr120]

Koushik, So sory again but could you please add 31 and 32 videos into playlist

[@susovanmaji7518]

Can't use RouterFunction and RestController together in a single app. RouterFunction API is giving proper response but RestController API is throwing exception, is this restricted in SpringBoot ?

[@revathiruby8541]

How to add more than tuple8

[@joshuadelarosa2666]

Just wondering why is there no subscribe() on the Controller methods?

[@josealonso7321]

Spring does it automatically.

[@shaikakbarali5257]

why there is no subscribe method here. Can someone clear me on this.

[@sanakamal5533]

What's reactive programming?

[@hubertm3466]

wtf is this font man

[@ravi-thestar8501]

This guy turned commercial now a days.. i was very proud of this guy since many years.. suddenly turned commercial. Not sure what made him to do that.. better create another channel if you wanna sell anything..

[@updownftw_]

What has he done that relates to commercial ? Tell me one more channel who is teaching this stuff for free at this level. We are lucky to have him.

[@ravi-thestar8501]

@@updownftw_ n no of channels

[@updownftw_]

@@ravi-thestar8501 yeah, I saw most their videos before Koushik’s and never understood Reactive programming. That’s why I said “at this level”. Koushik made it easy by giving real world examples and comparing it with Java Streams. Creating 30+ lectures, what more can you ask for free. This guy is one of the reasons why I’m so into the software industry.

[@ravi-thestar8501]

@@updownftw_ may be true.. but i referring the commercial turned side of him. Dont take it personal

[@DeathBender]

"turned commercial" is a very selfish approach for saying "i want anything for free" and compared to what you might give Koushik and receive in return, it's 100% worth it i've scoured a metric ton of YT Java content and this channel is really that good ! if you feel you don't need the content that would require a subscription then there's still alot of free content here and i guarantee you will still have to scrounge bits and pieces from a alot of other channels (and most of the time not providing the same quality or are simply not up to date). This is the only channel on YT im subscribed to (as in: that im paying for) ! :)
