    摘要: An improved system and method for writing data dependent upon multiple reads in a distributed database is provided. A client may read several data records and may then send a request to a database server to perform a transaction to write a data record dependent upon multiple data records read. A database server may receive the request specifying a transaction to write a data record dependent upon multiple data records read and may perform the transaction by latching a master data record to be written and validating the data records the write depends upon. The multiple data records upon which the write depends may be validated by verifying the multiple data records are current versions of the data records stored in the distributed database. Data intensive applications may use this transaction type in large scale distributed database systems to provide stronger consistency without significantly degrading performance and scalability.

    摘要: An improved system and method for parallel retrieval of data from a distributed database is provided. A parallel interface may be provided for use by a cluster of client machine for parallel retrieval of partial results from parallel execution of a database query by a cluster of database servers storing a distributed database. A query interface may be augmented for inputting a database query and specifying the number of instances of parallel retrieval of results from query execution. To do so, a commercial query language may be augmented for sending a query request that may include a parameter specifying the database query and an additional parameter specifying the desired retrieval parallelism. The augmented query interface may return a list of retrieval point addresses for retrieving the partial results assigned to each of the retrieval point addresses from parallel execution of the database query.

    摘要: A method, an apparatus, a computer-program product, and a system for determining bandwidth for transmission of data packets are disclosed. A data packet in a plurality of data packets is received. An amount of bandwidth required for transmission of the received data packet is determined. The amount of bandwidth is a portion of a total available bandwidth for a radio link. At least one condition associated with the radio link for transmitting the received data packet to a user device is determined. Based on the determined amount of bandwidth and the determined condition, the received data packet is transmitted to the user device. Another data packet in the plurality of data packets is transmitted using another portion of the total available bandwidth.

    摘要: The system includes a query engine and an advertisement engine. The query engine is configured to receive a query from the user. The advertisement engine generates advertisement results corresponding to the query. The advertisement results are selected from entries in an advertisement database, where the entries include predicate values corresponding to a domain. The advertisement engine generates a diverse advertisement result that is a subset of the database entries that match the query. The diversity result varies at least one predicate by selecting entries for the list that include a proportional representation of each available predicate value in the database that matches the query.

    摘要: Techniques that support trail-based exploration by a user of a repository of documents are described herein. In one embodiment, trail definition data that specifies a trail is received. The trail includes an ordered series of waypoints including a trailhead, intermediate waypoints, and one or more trailends. In some embodiments, deadends may also be defined in the trial. A particular waypoint in the ordered series of waypoints is established as a current waypoint. Search terms can be received from a user to cause a search to be performed. It is then determined whether the search satisfies matching criteria associated with a waypoint that immediately follows the current waypoint in the ordered series of waypoints. If so, the user advances to the next waypoint. Otherwise, the user remains at the current waypoint. Finally, if a trailend is reached, then an action such as rewarding the user in some way may be performed.

    摘要: A system and method for generating advertisements based on search intent. The system includes a query engine, and an advertisement engine. The query engine receives a query from the user. The query engine analyzes the query to determine a query intent that is matched to a predetermined domain. A translated query is generated including the domain type. Once a domain is selected, the query may be further analyzed to determine generic domain information. The domain and associated information may then be matched to a list of advertisements. The advertisement may be assigned an ad match score based on a correlation between the query information and various listing information provided in the advertisement.
