Abstract: Techniques for singleton coordination in an actor-based system are described herein. In some examples, one or more actors within an actor based system may be designated as singleton actors. Each singleton actor is permitted to have only a single associated instance in the actor-based system. In some cases, when multiple executing instances (i.e., duplicates) of a singleton actor are detected, the duplicates may be resolved, for example, such that no more than a single instance of the singleton actor is retained. In some examples, one or more singleton coordinators may be responsible for selecting one or more hubs on which to generate new or re-generated singletons, monitoring existing singletons to ensure that they continue to execute, and re-generating existing singletons after termination.
