Thank you for your response and the idea! Regarding your custom ModelActor — do you also need to properly set the var unownedExecutor: UnownedSerialExecutor ? Implementing everything in a single custom actor, including all read and observation tasks, seems a bit too much for my use case. Is there any reason not to use multiple such custom actors? I’ll definitely give the custom ModelActor approach a try right away! Thanks again!

Thank you for your response and your ideas. I’ll give that a try!
