    摘要: A group of shared-storage resources are being maintained as replicas by the nodes of a cluster. Each node in the cluster maintains a set of pointers to the members of the group. As membership changes, the set of pointers should be changed accordingly. For various, reasons, the set of pointers of a node are not changed and may point to shared-storage resources that are no longer members of the group and/or not point to shared-storage resources that are members of the group. By recording a history of membership changes in the shared-storage resources, and comparing the recording to what a node thinks the shared resources should be, an incorrect set of pointers can be detected and corrective active undertaken.

    摘要: A system and techniques are described for managing key-value pairs using an architecture that does not restrict its users to any specific platform or storage subsystem. According to one aspect of the invention, the repository is portable in that the architecture need not change based on the environment and platform in which the repository is used. Rather, the portion of the architecture that is platform-specific is limited to plug-ins at a storage abstraction layer of the repository. The plug-ins expose the same storage abstraction interface to the other layers of the repository, but are implemented to interact with different platforms and storage subsystems. Consequently, in response to being ported from one platform to another, the repository may simply change the plug-in to invoke for persistent storage operations.

    摘要: A method and mechanism for managing data to resolve incompatibilities between different versions of data is disclosed. According to one approach, incompatibilities to private data is managed using group/member dependent key(s)/link(s), static shared data is managed using group/member dependent key(s)/link(s), and dynamic shared data is managed using data transformation function(s).

    摘要: Described herein is a mechanism that follows, at least in part, an object oriented design pattern. In particular, a class is used to model a shared resource as a shared resource object. The class creates one instance of the shared resource object in response to multiple attempts to create a shared resource object from the class. The class defines various methods used to interact with the object. The object receives requests to perform operations from the clients. The clients may register another object to receive from the shared resource object notifications regarding events about the operations requested by the clients.

    摘要: A system and method for facilitating an automatic rolling upgrade of distributed software. In a set of computing devices (e.g., a cluster), each node executes the distributed program, but different nodes may operate any number of different versions of the program. During a rolling upgrade of the software, the nodes all operate according to a specified acting version of the software. A node attempting the join the cluster may be required to have a software version at least equal to the acting version. When all nodes have been upgraded to a version newer than the current acting version, the acting version is reset to the lowest software version installed on a node. The rolling upgrade completes automatically when all nodes run at a specified software version (e.g., the most recent) or have the same version installed.

    摘要: An aspect of the invention provides a method for managing information associated with a hierarchical key. A plurality of hash tables are created for a plurality of levels of a hierarchy associated with a hierarchical key, wherein each hash table is associated with a corresponding level of the hierarchy. Entries are stored within each of the plurality of hash tables, wherein the entries are associated with key names that have as many levels as the level associated with the respective hash table. Furthermore, a reference to a descendant entry that is in a respective hash table may be stored within each entry.
