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： A computer user may use a computing environment comprising a set of computers that respectively feature a web browser having a browser cache containing many types of data objects, including application resources and user-generated data files. However, the contents of a browser cache significantly contribute to the computing environment of a computer, and the computing environments presented by each computer may diverge, providing an inconsistent computing environment. Instead, the contents of browser caches of the computers comprising the computing environment may be synchronized across computers. Additionally, the browser cache may be synchronized with the other data objects of a computing environment (such as relevant portions of the filesystem); the synchronizing may be implemented as an out-of-browser process executing independently of the applications, and even when the browser is not executing; and the synchronization may be exposed through a programmatic access with which web applications may interact.

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： A data store is configurable in terms of various tradeoffs including consistency and availability, among others. Consistency can be specified in terms of one of a myriad of configuration levels. Availability can be specified with respect to a maximum and minimum number of replicas or failure tolerance. In operation, one or more of write or read quorums can be automatically adjusted to ensure satisfaction of a specified configuration level in light of changes in the number of replicas.

摘要： An application on a device may interact with a document service that provides access to a document service. The interaction may occur in a variety of contexts, such as a device context (e.g., the document service and the application provided on the same device), a local context (e.g., via a LAN), and a remote context (e.g., over the Internet). It may be advantageous to adapt the interaction to the current context, while also providing a consistent application interface that alleviates the application from context-specific implementations, and also achieving this adaptation in a performant manner. These considerations may be achieved in a balanced manner by providing a set of runtimes, where each runtime mediates the application/document service interaction between the application and the document service in a contextually adapted manner. The device may automatically detect the context of the interaction and select a contextually suitable runtime to service the application.

摘要： Within a computing environment, an application may run in a variety of contexts, e.g., as a natively executable application, as a client-side interpretable application embedded in a web browser, or as a server-side application that communicates with the user through a web interface presented on a device. The application may also access resources of the computing environment stored on multiple devices. The configuration of the application to operate equivalently in these diverse environments may be facilitated by representing the application within an object hierarchy representing the computing environment. The application may be configured to operate on the objects of the object hierarchy regardless of the location of the stored objects, to execute on any device, and to execute upon a standard set of application programming interfaces. The configuration of the application in this manner promotes the versatility of the application in operating equivalently in different programming contexts.

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.

摘要翻译： 文档集（如关系数据库中的XML文档或记录）的查询模型通常涉及定义文档结构的模式。 然而，刚性定义的模式通常会导致文档验证的困难，甚至无关紧要的结构变化。 另外，针对模式约束的文档开发的查询通常对结构细节和对查询不重要的变体敏感，导致不准确的结果和开发复杂性，并且可能会破坏模式更改。 相反，用于分层结构化文档的查询模型，使得“twig”查询仅指定与查询相关的文档节点的结构细节（例如，具有名为“Lee”的兄弟姐妹的学生数据库中的学生和名为“Smith”的教师， “不管文件的不相关的结构细节如何）。 这种“twig”查询模型可以实现更自然的查询开发，以及在不相关的模式变化和变化的情况下，查询的持续准确性。

摘要： A service level agreement can be generated based on a data store configuration. In one instance, the configuration can be specified in terms of a data value such as high, medium, and low value, for example. In another instance, a workload configuration can be specified comprising a replica set and consistency level, among other things. More particularly, the service level agreement can include guarantees regarding one or more of consistency, availability, latency, or fault tolerance, among others, as a function of a data value or workload configuration. Further, operation of a service associated with a service level agreement can be monitored to determine satisfaction or violation of guarantees, and provide real time feedback.
