Reactive Spring Boot With Kotlin Coroutines: Adding Virtual Threads

[@varunshrivastava6845]

This is one of the best explanation of how coroutines and virtual threads works. And also how springboot has incorporated these changes. Kudos to Urs Peter!!!!!

[@RockyJaiswal]

This is one of the best talks I have seen and I have been trying to get Async + VT + Coroutines right for the last year or so and this talk answers all the questions and gives clear explanation of each model.

This is amazingly clear and well explained, I'm gonna send this to all backend engineers of the company I work at as a must-watch!

[@sushovanchakraborty1028]

The best explanation of virtual threads till date.

Clojure and spring webflux, is very simple to use also, functional dynamic, not spagheti code you just follow the flow. For people that like functional programming and data processing at least. Talk was very nice! Thank you.

Really good explanations. But I kinda got lost in between switching good/bad approach in the end. I will have to watch it one more time I guess. Just a straightforward kotlin coroutines with spring boot+virtual threads would be nice. Keep up the good work. Cheers.

Amazing explanation. Congrats @Urs Peter

Good evening.Cheers

this is brilliant which I have searched

What has been said by Peter at 25:24 is not correct. It did not go Out Of Memory. What happened in reality is that you hit the max number of native thread your OS allows you to create per java processor. The error says "possible out of memory OR PROCESSOR/RESOURCE LIMITES REACHED. If you reduce the available amount of heap, lets say 1GB or 512MB or even less, probably you will see the exactly same error and you will be able to create the maximum number of threads your OS allows you to create. An "empty" Platform Thread occupies 1/2MB of STACK not heap. Cheers.

This was excellent. can we get the demo project from some where - presentation-springboot-coroutines?

[@Kotlin]

Thanks for asking! Please find the link to the demo project in the description of the video.

Hi, what kind of tool Mr Urs Peter use for testing the performance of the spring boot app?

[@АлександрСуходолов-э9ы]

Thanks very much for this video! Was really interesting. I am never used relational DB with async drivers (only with jdbc), but use reactive MongoDB driver with Web Flux + Reactor or WebFlux + Coroutines. But I heard about some issues with using Hibernate and RDBMS. Does VT can help to use smoothly classic JDBC with Hibernate (using own thread pool with VT) in reactive app used on (Web Flux + Reactor/WebFlux + Coroutines)?
