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!!!!!
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.
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.
Great video! Really open my eyes on some concepts. I enjoyed every minute of it and convinced me what a great language is Kotlin. Java dev here, never touched Kotlin so far in my life, but sure looks promising and will be quite curios to give a try in the future
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.
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 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!
The best explanation of virtual threads till date.

this is brilliant which I have searched
Good evening.Cheers
thx ❤
This was excellent. can we get the demo project from some where - presentation-springboot-coroutines?
Thanks for asking! Please find the link to the demo project in the description of the video.
@@Kotlin thanks a lot！😃😃😃
@@Kotlinthanks but i cant see any link in video description
@@user-hi3dj6wh7d you need to click to expand the description text - there will be the link
Hi, what kind of tool Mr Urs Peter use for testing the performance of the spring boot app?
