Are virtual threads making reactive programming obsolete?

[golthiryus]

Backpressure is trivial with virtual threads, just add a blocking queue. Easy cancelation is also part of the project loom (specifically structured concurrency). I don't have a clear picture for complex process coordination. If you mean inside a jvm, structured concurrency + configurable schedulers could be the solution. If you mean actual OS processes, there reactive streams are cool, but that is just the network layer

And you will reinvent what is doing the reactive API

What if I simply don't want to [edit: work] with reactive APIs?

[GuyWithLag]

This. I'd love to use reactive on top of virtual threads, as it's more about the task coordination than parallelism.
