Abstract: Examples relate to providing concurrent dead actor collection. In some examples, a blocked notification is received from an actor of a number of actors in a distributed system, where the actors are arranged in an actor hierarchy that describes communication links between the actors. In response to receiving the blocked notification, a blocked status is requested from each other actor in a loop subset of the actors, where each of the other actors is connected to the actor in the actor hierarchy by an incoming edge. After using the blocked status of each of the other actors to determine that incoming edges of the actor refer to blocked actors, the actor is designated for garbage collection.

Abstract: According to an example, copy-on-write (COW) update-triggered consistency may include determining a first shared version related to a shared set of data related to a process involving a first application and a process involving a second application. First and second local versions may be respectively assigned to the shared set of data associated with the first and second applications. Initiation of a commit process by the first or second applications may be determined respectively based on a write to the first or second local versions respectively related to the shared set of data associated with the first or second applications. In response to initiation of the commit process, a second shared version may be generated related to the shared set of data based on the respective processes involving the first and the second applications.
