Describe the solution you'd like
Need to several things:
- May need to slightly abstract workflow concurrency impl to support (but may not)
- Update Kotlin project to add support for Kotlin coroutines in workflows and activities as Kotlin
suspend funcalls (may need to be opt-in in some way). There is an internal POC implementation from @mfateev we can leverage here. - Create a new Java 21+ only "temporal-virtual-threads" project that uses virtual threads for workflow concurrency and runs activities in virtual threads (may need to be opt-in in some way)
This is kinda a big project, so some discussion should happen first. The above is just speculation about what to do.
