single thread executor

[Ron Pressler]

Hi.

Custom schedulers were not delivered as part of JEP 425, as they are not yet ready for release.
We intend to add that feature at a later date. Until then, only the default scheduler can schedule virtual threads.

Google search for a similar use case led me to this discussion.

It seems that API has changed in the latest builds.

What is the current way to achieve the following?

Thread.builder().virtual(Executors.newSingleThreadExecutor()).factory()

Thanks,

Reference to the original thread (in case this email shows up outside the original thread, not sure how mailman works):

Remember, you want multiple virtual threads, but use only on platform
thread to schedule them. So you need to pass the single-thread executor
as the virtual thread scheduler:

    ThreadFactory tf = Thread.builder().virtual(Executors.newSingleThreadExecutor()).factory(); And then you can use the thread factory directly to create virtual threads, or use it like so:     ExecutorService e = Executors.newUnboundedExecutor(tf); - Ron
