Create a runtime instance every time or share one?

[ScottLinnn]

I want to let all my microservices run on the current thread and I don't want to use the main macro. Should they use the same single-threaded runtime instance or share the same one?

If you want these microservices to run on the same thread, you should put them all on once shared current_thread runtime. If you want them to each have their own thread, you should use a separate current_thread runtime for each.
