how to create new forkjoinpool context like CommonPool

[Jaware]

in our situation,runtime cpu core size is too large because of the docker,so i want to create new forkjoinpool and use it as the coroutine's running context,there is no docs about how to do that,can anyone show me

Currently, there is no such option.
I think we can add configuration via system property for such specific cases

Are you looking for something like

ForkJoinPool(2).asCoroutineDispatcher()

However the JVM 10 works well in a container.

[qwwdfsad]

The downside of this approach is that now you should explicitly use new dispatcher everywhere.
It may be applicable, but it's not the most convenient option

thanks for your reply,can i use this 'ForkJoinPool(2).asCoroutineDispatcher()' way in production?

[Jaware]

our k8 docker cluster use cpu sharing mode with mashine @fvasco ,so the 'Runtime.getRuntime().availableProcessors() ' is not my container's cpu count

[fvasco]

This was fixed in JVM 10, alternatively you can safety use asCoroutineDispatcher

thanks @fvasco
