摘要： A server set may provide a document service to one or more clients, and may be configured to do so in view of various considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and configuring respective servers of the server set to host one or more agents to which are respectively assigned one or more document ranges. A request for an operation involving at least one document may be routed to a server hosting an agent managing the document ranges of the documents involved in the operation. Moreover, respective servers may retain detailed information about neighboring servers (e.g., according to a logical or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.

摘要翻译： 服务器集合可以向一个或多个客户端提供文档服务，并且可以被配置为考虑到可用性，容错性，灵活性和性能等各种考虑。 这里提出的是涉及将文档集划分成至少两个文档范围并且配置服务器集合的相应服务器以托管一个或多个分别被分配有一个或多个文档范围的代理的文档服务体系结构。 涉及至少一个文档的操作的请求可以被路由到托管代理人的服务器，该代理管理该操作涉及的文档的文档范围。 此外，相应的服务器可以保留关于相邻服务器的详细信息（例如，根据逻辑或物理接近）以及关于远程服务器的少量信息，从而避免了高度通用的网络架构的广泛的信息交换和不知情的路由算法的低效率。

摘要： A document service may be provided by many document service packages, each presenting a particular set of service characteristics (e.g., the performance achievable on various storage device types; the available indexing models; and the types of transactions, scripts, and queries supported by the document service). For a particular project, an administrator may endeavor to select a document service package exhibiting characteristics that match some criteria of the project and to configure or adapt the document service for other criteria, but the range of adaptability for each document service package may be limited. Presented herein are architectures for document services involving a composable set of components respectively providing a service feature with a service characteristic. The document service may be automatically composed by, for each service feature of the document service, selecting a service component for the service feature that matches the service criteria specified in a service level agreement.

摘要翻译： 文档服务可以由许多文档服务包提供，每个文档服务包都提供特定的一组服务特征（例如，可在各种存储设备类型上实现的性能;可用的索引模型;以及支持的事务，脚本和查询的类型 文件服务）。 对于特定项目，管理员可以努力选择展现与项目的某些标准匹配的特征的文档服务包，并且为其他标准配置或调整文档服务，但是可以限制每个文档服务包的适应性范围。 这里提出了用于文档服务的架构，其涉及可组合的一组组件，分别提供具有服务特征的服务特征。 对于文档服务的每个服务特征，文档服务可以被自动地组成，为服务特征选择与服务级别协议中指定的服务标准相匹配的服务组件。

摘要： A server set may provide a document service to various clients in view of considerations such as availability, fault tolerance, flexibility, and performance. Presented herein are document service architectures that involve partitioning the document set into at least two document ranges, and assigning the respective document ranges to an agent that is deployed to at least one assigned server. A request to apply an operation to a selected document may be fulfilled by identifying the document range of the document; identifying a selected server of the server set that hosts the agent to which the range is assigned; and forwarding the request to the selected server. In some variations, servers may retain detailed information about neighboring servers (e.g., according to logical and/or physical proximity) and scant information about distant servers, thereby avoiding both the extensive information exchange of highly informed network architectures and the inefficiency of uninformed routing algorithms.

摘要： Object-oriented application languages often provide resources to applications for accessing objects stored in the volatile application memory region, and, separately, for packaging objects for persistent storage and network transport by serialization and deserialization involving a storage format. However, this design creates discrepancies between the application language and storage format, and depends on affirmative serialization and deserialization by the application. Presented herein are techniques for providing object access to objects involving persisting the objects as documents in a document store, where such persistence occurs automatically upon object creation and updating, and where such objects are stored in a language format integral to the application language (e.g., when a JavaScript application creates an object, the objects are automatically stored as documents of the document store in a JavaScript Object Notation (JSON) format). This design enables various advantages in efficiency, flexibility, and seamless interaction between the application and the objects.

摘要： Query models for document sets (such as XML documents or records in a relational database) typically involve a schema defining the structure of the documents. However, rigidly defined schemas often raise difficulties with document validation with even inconsequential structural variations. Additionally, queries developed against schema-constrained documents are often sensitive to structural details and variations that are not inconsequential to the query, resulting in inaccurate results and development complications, and that may break upon schema changes. Instead, query models for hierarchically structured documents that enable “twig” queries specifying only the structural details of document nodes that are relevant to the query (e.g., students in a student database having a sibling named “Lee” and a teacher named “Smith,” irrespective of unrelated structural details of the document). Such “twig” query models may enable a more natural query development, and continued accuracy of queries in the event of unrelated schema variations and changes.
