Does anyone know how to pass data from entity world to classic one?

Title. I'm looking for some approach to transfer data from the job systems to the default Unity. (E.g. data for UI)
Will something like UniRx work?
E.g. passing the data to the main thread dispatcher that will process it after that in the main thread (via static call)?

Any gotchas except that burst won't work?

 

either use a ComponentSystem with Hybrid setup (GameObjectEntity)
or store the Entity in a MonoBehaviour and fetch the components with EntityManager.GetComponentData<T>(entity);

are you totally sure that the dispatcher itself is thread-safe? even if it is, if it uses locks the performance may be worse that single-thread

 

Right, GetComponentData<T> is probably the way, but I'd rather prefer something reactive.
Dispatcher is thread safe, I've already used it for sending events between threads. Not sure about the locks tho, might need to investigate that.
