摘要： In a networked computer system that includes multiple nodes and multiple networks interconnecting the nodes, a database query optimizer takes network choice into consideration when optimizing a query. The query optimizer logs historical information for queries that includes network information. A network monitor determines network characteristics of the multiple networks. The query optimizer then selects a network for a query based on the network characteristics, and optionally based on the historical information as well. The result is a query optimizer that takes network choice into consideration, thereby providing a query that is optimized according to the characteristics of the networks.

摘要： The present invention generally relates to data processing and, more particularly, to managing operation of user-defined functions on a partitioned database. One embodiment provides a computer-implemented method for managing execution of a query against a partitioned database having a plurality of data partitions. The method comprises, for each of the plurality of data partitions, examining data of the data partition, and on the basis of examined data, implementing a modified form of a user-defined function on the data partition. The method further comprises executing the query referring to the user-defined function against the plurality of data partitions, wherein execution of the query on each data partition invokes execution of the respective modified form of the user-defined function against the data of the respective data partition.

摘要： Techniques are described for estimating and managing energy consumption for query processing. Embodiments of the invention may generally receive a query to be executed and calculate an initial estimated energy consumption value for the received query. If the initial estimated energy consumption value does not exceed a threshold amount of energy, embodiments of the invention may submit the query for execution. Once execution of the query has begun, embodiments of the invention may calculate an updated estimated energy consumption value for the executing query, and if the updated value exceeds the threshold amount of energy, may halt the execution of the query.

摘要： Techniques are disclosed for processing data streams containing data tuples, where some of the data tuples are load shed. Load shedding refers to a process of selectively discarding some data tuples, e.g., when the amount of received data becomes too overwhelming to manage. When operations are invoked that depend on the values (or count) of the load shed tuples, the value (or counts) of the load shed tuples may be used to perform such operations. For example, and aggregation operation may return the sum, average, mean and/or variance associated with a plurality of tuples processed by a node of the stream application.

摘要： Embodiments of the invention enable a database spread over multiple nodes to allow each node to have different indexes over the data in tables, depending on how each node would benefit (or not benefit) from having the index(es). When a database table is spread across the nodes of a multi-node or distributed system, each node may maintain only the portion of the index relevant to that node, if doing so would improve the performance of query processing operations on that node. Further, the database may periodically redistributed across the compute nodes based on index performance. Doing so allows the database system to intelligently trade off between consuming space for the index on a node and the usefulness of having an index on that node.
摘要翻译： 本发明的实施例使得数据库能够跨越多个节点进行扩展，以允许每个节点相对于表中的数据具有不同的索引，具体取决于每个节点如何从获得索引而获益（或不受益）。 当数据库表分布在多节点或分布式系统的节点上时，每个节点只能维护与该节点相关的索引部分，如果这样做可以提高该节点上的查询处理操作的性能。 此外，数据库可以基于索引性能周期性地重新分布在计算节点上。 这样做允许数据库系统在节点上的索引的消耗空间和在该节点上具有索引的有用性之间进行智能折中。
