摘要
A method, for handling partially inconsistent states among members of a cluster in an erratic storage network that responds to requests from a client, includes assigning a unique commit identifier corresponding to each successive modification of state of the cluster when an update request has been successfully completed and correlating an incoming request to a given member of the cluster with any commit identifiers necessary to satisfy the request. The method further includes detecting, on the incoming request to the given member of the cluster, whether the commit identifiers necessary to satisfy the request have been applied to the given member, and processing the incoming request based on whether the commit identifiers necessary to satisfy the request have been applied to the given member. Operation of the members can be asynchronous.
