摘要： Techniques are provided for changing data for an XML construct in an SQL/XML compliant database management system (DBMS). The DBMS allows instances of XML type to represent XML constructs, such as XML documents, XML elements, XML attributes, and fragments of XML documents. An SQL statement is received that includes an XML operator that operates on a particular component in an instance of XML type. During execution of the SQL statement, the XML operator is evaluated by modifying content for the component without modifying the entire instance. For example, an XML delete operator deletes the particular component from the instance. Other XML operators include an insert operator, an insert-before operator, an append-child operator, and an update operator. During execution, these operators may be rewritten to operate on existing SQL constructs, or evaluated by updating only some of the existing SQL constructs, or both.

摘要： Systems and methods that aggregate memory capacity of multiple computers into a single unified cache, via a layering arrangement. Such layering arrangement is scalable to a plurality of machines and includes a data manager component, an object manager component and a distributed object manager component, which can be implemented in a modular fashion. Moreover, the layering arrangement can provide for an explicit cache tier (e.g., cache-aside architecture) that applications are aware about, wherein decision are made explicitly which objects to put/remove in such applications (as opposed to an implicit cache wherein application do not know the existence of the cache).

摘要： Constraints that restrict how corresponding identifiable groups of files are stored in a database, are enforced on corresponding file data. In response to a query on any data from an identifiable group of files, the effect of the constraint on how the corresponding data is stored is determined. The original query is rewritten, based on the effect of the constraint, so that the rewritten query is directed to a particular subset of the data stored in the database. Consequently, the search space is restricted to an identifiable subset of the database and execution of the rewritten query is more efficient than execution of the original query.

摘要： Aspects of the subject matter described herein relate migrating message for a messaging service. In aspects, a determination is made that messages need to be migrated based on a threshold being crossed. In response, an agent is instructed to migrate data associated with the messages to another location. The agent uses various factors to determine one or more queues to migrate. While a queue is being migrated, during a first portion of the migration, messages may be added to and removed from the queue as senders send new messages and receivers consume messages. During a second portion of the migration, the queue is frozen to disallow the queue to be used for receiving new messages and delivering queued messages. The migration may be orchestrated to attempt to achieve certain goals.

摘要： Version indicators within an existing range can be associated with a data partition in a distributed data store. A partition reconfiguration can be associated with one of multiple partitions in the data store, and a new version indicator that is outside the existing range can be assigned to the reconfigured partition. Additionally, a broadcast message can be sent to multiple nodes, which can include storage nodes and/or client nodes that are configured to communicate with storage nodes to access data in a distributed data store. The broadcast message can include updated location information for data in the data store. In addition, a response message can be sent to a requesting node of the multiple nodes in response to receiving from that node a message that requests updated location information for the data. The response message can include the requested updated location information.

摘要： An XQuery access API is described, for providing access to XML data from a data source, using the XQuery language. A requestor can request, from a server, performance of an operation on XML data, wherein request messages and response messages conform to the Simple Object Access Protocol (SOAP). Request and response messages can be transmitted using Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol over Secure Socket Layer (HTTPS). The format of the request and response messages is specified in a definition of a Web service, where the definition conforms to the Web Service Description Language (WSDL).

摘要： A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety of sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.

摘要： Systems and methods that supply a replication layer/agent that is generic to supporting a plurality of storage configuration as part of a distributed store. Such distributed store employs a Common Availability Substrate (CAS) for data transport and consistency, to render the distributed store scalable and available. Such an arrangement enables continuous operation of the store, while the replication subsystem creates new replicas (e.g., for load balancing, failover, and the like).

摘要： Transformation of a set of XML documents via an XSLT stylesheet is made more efficient by rewriting the stylesheet at compile-time, based on the structural description of the set of XML documents, into an optimized stylesheet containing fewer dynamic template-matching calls than the original stylesheet. This rewritten stylesheet can be further rewritten into a set of XQuery expressions. At compile-time, the particular transformation templates that are appropriate for transforming the particular nodes contained in the set of XML documents are determined, and XSLT calls to the templates are converted to calls to corresponding XQuery user-defined functions. Determination of the appropriate transformation templates may be based on the structural description of the input set of XML documents, such as an XML Schema or Document Type Definition. The data from each template is translated into corresponding XQuery constructors, instructions from the template are translated into XQuery expressions, and the XQuery functions are inlined if possible.

摘要翻译： 通过XSLT样式表转换一组XML文档通过将编译时的样式表（基于XML文档集的结构描述）重写为优化样式表，使其具有比原始文本更少的动态模板匹配调用 样式表。 这个重写的样式表可以进一步重写成一组XQuery表达式。 在编译时，确定适合于转换XML文档集中的特定节点的特定转换模板，并将XSLT对模板的调用转换为对相应XQuery用户定义函数的调用。 确定适当的转换模板可以基于XML文档的输入集合的结构描述，例如XML模式或文档类型定义。 来自每个模板的数据被转换为相应的XQuery构造函数，模板中的指令将被转换为XQuery表达式，如果可能的话XQuery函数是内联的。
