Thank you so much brother for such informative videos.
When you get chance please do make videos on Spring batch and Spring security as well.

[Chaitra_Navratri]

Please increase the pace to upload your springboot videos.lots of things yet to cover.we will miss opportunities please its a request

[vk]

Very informative videos Shrayansh. You are doing a great deed by sharing your in depth knowledge. Just a request keep posting more videos in Spring Boot playlist.

[sarthakagarwal]

Thanks for putting in a lot of efforts and time for create such valuable and in depth videos
It would be amazing if you could create videos on Spring Security and Spring Batch as well. Thanks for sharing such valuable knowledge

[debojeetc]

Please explain this : both ThreadPoolTaskExecutor and SimpleAsyncTaskExecutor can be used as defaults, how are they chosen ?

[NiranjanPadhi-fgrg]

Heyy Shreyansh Looking For Your Videos on Scheduling as u already said u worked on it so much excited for that ☺
And Thanks for putting in a lot of efforts and time for create such valuable and in depth videos

DefaultExecutor gets picked: when no executor is defined in the config.
ThreadPoolTaskExecutor gets picked: if it is provided in the config.
SimpleAsyncTaskExecutor gets picked: if ThreadPoolExecutor is provided but @Async lacks its name
ThreadPoolExecutor gets picked: if it is provided in in the config and @Async has its name.
(Mine understanding: might delete later.)

43:46 shouldn't we use Bill Pugh solution here to make it completely thread safe?

[parthatara]

I have a doubt: When is the SimpleAsyncTaskExecuter is used and when does the Spring boot create a default INT.MAX ThreadPoolTaskExecuter. It seemed like for above both if there is no bean defined then they are supposed to happen.

[reyyisuresh]

Why in industry standard we are not using ThreadPoolTaskExecutor as a default one ?
Why Java ThreadPoolExecutor with AsyncConfigurer ?

[aditimahabole]

please make video on how to use JWT in springboot, also tell about srping web security

[samanthafox]

Why UserService is annotated by @Component? Why are you spawning off new threads everytime instead of relying on threadpoolexecutor? this code is exhausting the memory of the system. What if the number of threads needs to be decreased or increased from your magic number 8

[nishchayakumar]

I have a question: if the task is rejected, where will it go since neither the queue nor the thread pool is available? When will it be available for processing?

[terteseamos]

Can you discuss on how we can improve api performance that call db multiple times when processing a certain report record ? how can we use background threads to improve the Api performance

[rajanikushwah]

why someone will not create a threadPoolTaskExecutor bean and go for implementation of AsyncConfigure?

[Randomvideo]

Hi Shrayansh, for use case 3 if don't mention our own bean name along with @Async annotation then SimpleAsyncTaskExector will get picked then how thread name can go beyond 8 as like SimpleAsyncTaskExector-9 as min size of pool is 8.

Hi Shreyansh, I’m enjoying your content, but I wanted to bring something to your attention. I’ve noticed that in your Udemy courses, the audio is cracking/distorted. The same videos on YouTube play perfectly without any issues. This audio problem on Udemy is really affecting learning experience. I hope this can be fixed soon because otherwise, Udemy won’t be as useful. Thanks for your great work!

[Randomvideo]

Also how main thread is created is there any configuration of threadpool for main thread also?

[SagarAnkitaUpdates]

I have taken your channel’s membership but still unable to watch videos which are limited to members? How to get access to your exclusive videos?

How to make queue size, min pool and max size pool size dynamic?
