Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for ordering events within a distribution computing system are described. In one aspect, a method includes receiving, by an upward node from one or more nodes of a distributed computing system, event fragments for corresponding events that have occurred within the distributed computing system. Each event fragment includes an age parameter that indicates an age of the corresponding event from a perspective of a node that sent the event fragment to the upward node. The upward node calculates, for each event, a corresponding disentangled time based on a received time that represents a time at which the upward node received the event fragment for the event and the age of the event indicated by the age parameter for the event. The upward node arranges the events in an order according to the disentangled time for each event.
