IAsyncEnumerable as Stateful Service method return value?

Question

IAsyncEnumerable as Stateful Service method return value?

Miloš D. Ljubisavljević 1

Is there a way to return IAsyncEnumerable in Stateful Service method, like in regular ASP .NET Core services?
Returning large amounts of rows from db is getting really slow using Task<IEnumerable<>>.

I tried doing that using Task<Fabric.IAsyncEnumerable> but I still dont get expected results, and also couldnt find any solution online. If this is expected and I am mistaken, please point me to the right solution.

@Miloš D. Ljubisavljević Have you tried below:

IAsyncEnumerable is remotable or streamable, but what most people do is return data in segments or chunks, with the client being able to know how far it has made it and then request more data from where it left off.

Thanks
