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： Network and storage calls are reduced by batching messages. Messages are collected from a client and sent to the gateway or backend application in one round trip. Alternatively, the messages are collected for different entities, and the batched messages are durably stored. Related messages, which may have the same sessionID, are grouped into a logical unit or session. This session may be locked to a single message consumer. A session may be associated with an application processing state as an atomic unit of work while other operations are performed on the messages in the session. Acknowledgements are accumulated by a broker on a message server, but the messages are not immediately deleted. Instead, multiple messages in a selected range are periodically truncated from a message store in a single operation. Expired messages for active sessions are proactive cleaned up to prevent sessions from reaching a quota or limit.

摘要： A mechanism is provided for accessing XML data in a database system using a combination of a XML Table Index table and a XML Path Index table. By using a combination of a XML Table Index and a XML Path Index, both selection access and navigational access involved in a query can be optimized. For example, the XML Table Index gives the database system an ability to readily evaluate the predicate expression, thereby improving the selection access. Moreover, in some embodiments, the selection access can be further improved by using secondary indexes on columns contained in the XML Table Index table. In a complementary manner, the XML Path Index table gives the database system an ability to navigate to a specific location given a path expression, thereby improving the navigational access. Thus, by combining both tables, both selection and navigational accesses are improved.

摘要： Techniques are described herein for storing instances of data among nodes of a distributed store based on hierarchical scale unit values. Hierarchical scale unit values are assigned to the respective nodes of the distributed store. A first instance (e.g., a primary instance) of a data module is stored in a first node having a first hierarchical scale unit value. A primary instance of the data module with respect to a data operation is an instance of the data module at which the data operation with respect to the data module is initiated or initially directed. A second instance (e.g., a primary or secondary instance) of the data module is stored in a second node having a second hierarchical scale unit value based on a magnitude of a difference between the first hierarchical scale unit value and the second hierarchical scale unit value. A secondary instance is essentially a “back-up” instance.

摘要： Techniques for effectively and efficiently supporting XML sequence type and XQuery sequence natively in a SQL system are described. According to one aspect, SQL functions that correctly handle XML sequences are provided. Thus, XML sequences are handled effectively. According to another aspect, rules for simplifying an abstract syntax tree (AST) that represents one or more such SQL functions are provided. For each such SQL function that is represented in an AST that represents a SQL query, one or more rules that are relevant to that SQL function are determined. Relevant rules are applied to the representation of the SQL function within the AST. Through the application of the rules to the representations of the SQL functions within the AST, the AST is modified in a manner that simplifies the AST prior to the evaluation of the AST at query execution time. Thus, XML sequences are handled efficiently.

摘要： Search term ranking algorithms can be generated and updated based on customer settings, such as where a ranking algorithm is modeled as a combination function of different ranking factors. An end user of a search system provides personalized preferences for weighted attributes, generally or for a single instance of the query. The user also can indicate the relative importance of one or more ranking factors by specifying different weights to the factors. Ranking factors can specify document attributes, such as document title, document body, document page rank, etc. Based on the attribute weights and the received user query, a ranking algorithm function will produce the relevant value for each document corresponding to the user preferences and personalization configurations.
