I would love to see some patterns and real world problems solved with the new virtual threads 😊

[kappaj]

Agree - some code in action with best practices will be super helpful.

[IhorParashynets]

yes, some code in action and best practices would be nice to see... Thanks!

[tomassatas]

4 minutes into the video and finally you are on the topic.

[ivandenysenko]

Yes, please! It would be great to see some examples and patterns!

[nO_dNAL]

Really like the explanation of the motivation, it addressed the question of "but why is this a problem when we have thread pools?" I think the preview feature explanation in the first few minutes could be removed though, it's not the first preview feature and I'm sure the whole idea of previews is explained elsewhere but still, a nice reminder.

[HarmeetSingh]

Wow... a super awesome explanation and I am really excited to explore Virtual threads.

[Sergey]

Gosh can't wait when I start use all this staff like semaphores and lock I learned for interviews!

[marcoborgna]

I'm super thrilled by Virtual Threads but I feel will take so long before using in PROD env

[ahmadfx]

welcome back, yes we would like to see examples

[VisruthCV]

Very informative video, thanks for publishing!
11:54 is very important point!

[mars]

Some example and how things work under the hood would be amazing episodes.

[itlearner]

Nicely explained, thank you! Question what would be the impact of this on reactive programming?

[ahmedbouchaibi]

The end of Reactor pattern that i hate him, end to learn of go that i hate him also, I hope it will be in production as soon as possible, Thanks i love java

[bentels]

Of course, code examples are always good.

[NastyaSmirnova]

Great session. Thanks! I would like to see some code in action as well.

[ricklee-tjbu]

Greate vid!!

A thread reserves upfront 20MB in memory? can i get more detail information about it?

[sommyaruproy]

Show some examples with vthreads with blocking queries to db.

[romulopaiva]

Congrats!!! Very cool explanation! Next step: show me the code! 😁

[Concat]

Thank you for the informative presentation, and we wish to see code.
