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.

摘要翻译：描述了使用不将其用户限制到任何特定平台或存储子系统的架构来管理键值对的系统和技术。根据本发明的一个方面，存储库是可移植的，因为架构不需要基于使用存储库的环境和平台来改变。相反，平台特定的架构部分仅限于存储库的存储抽象层的插件。插件将相同的存储抽象接口暴露给存储库的其他层，但实现为与不同平台和存储子系统进行交互。因此，响应于从一个平台移植到另一个平台，存储库可以简单地改变插件以调用永久存储操作。

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 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： A new instance of an application is added to a group of existing instances (of that application) that share a resource, such as a database. The new instance is added by creating a new object for the new instance by cloning an existing object of an existing instance in the group, setting up connectivity between the new instance and a network through which the multiple instances communicate with one another, and starting up the new instance. The just-described acts are performed in the reverse order when deleting an existing instance. Each of these acts may be performed manually, or automatically without user input, with the user issuing at least one instruction to add or delete an instance.

摘要： In an application executing in multiple computers connected by a network, an instance of the application is deleted from a group of instances that share a resource, such as a database. Specifically the to-be-deleted instance is shut down, followed by deleting connectivity between the to-be-deleted instance and the network, and then deleting an object of the to-be-deleted instance. Each of these acts is performed automatically without user input, once the user issues an instruction to delete the to-be-deleted instance.

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.
摘要翻译：这里描述的是至少部分地遵循面向对象的设计模式的机制。特别地，类用于将共享资源建模为共享资源对象。该类创建共享资源对象的一个实例，以响应从类中创建共享资源对象的多次尝试。该类定义了用于与对象交互的各种方法。该对象接收从客户端执行操作的请求。客户端可以注册另一个对象，以从共享资源对象接收关于客户端请求的操作的事件的通知。
