Abstract
Event ordering is provided in a distributed file system. For instance, events are generated that are associated with an object collected from nodes in the distributed file system, and an event loop indicates causal dependencies among the events, and comprises one or more reliable edges and unreliable edges. Degrees of reliability of the unreliable edges in the event loop are determined, and then at least one unreliable edge is removed from the event loop based on the determined degrees of reliability. Causal dependencies among the events in the distributed file system are analyzed by using a statistical method, and the most unreliable edge in the event loop can be removed by computing a degree of reliability of each unreliable edge, thereby avoiding the occurrence of the event loop.
