Hello

I am working on a Ray actor that performs a busy loop in a synchronous method (sync\_method). To introduce concurrency, I have added async methods (async\_method) to the actor and am calling them from coroutines. I am not sure if the busy loop in sync\_method is blocking the execution of async methods concurrently.

I want to know ; how does Ray manage concurrency between sync and async methods within the same actor? Should I expect async methods going to run concurrently with a busy loop in a sync method, or do I need to implement specific patterns to achieve this? 🤔

What are the best practices for ensuring that both sync and async methods can execute concurrently within a Ray actor? I have checked [Newest 'ray-project-' Questions - Stack Overflow](https://stackoverflow.com/questions/tagged/ray-project-) [powerapps](https://www.igmguru.com/microsoft-training/powerapps-training/) guide but still need help .

I appreciate any advice on optimizing concurrency in this scenario.

Thanks!

Thank you 🙂
