摘要： A computer readable storage medium includes executable instructions to receive a request for data from a multi-dimensional cube divided into partitions distributed across nodes supporting a shared nothing distributed multi-dimensional database. The request is transformed into physical access layer operators in a tree structure. The tree structure is reduced into an index scan operator.

摘要： A computer readable storage medium includes executable instructions to define an interface to a multi-dimensional cube divided into partitions distributed across nodes supporting a shared nothing multi-dimensional distributed database. The interface includes a metadata module characterizing access paths to data within the multi-dimensional cube and an access path module to convert a data request into an access path protocol to retrieve data from the multi-dimensional cube to satisfy the data request.

摘要： A computer readable storage medium with executable instructions specifies the execution of a state machine operating across a set of computing nodes in a distributed computing system. The executable instructions execute a set of operators, where the execution of each operator is under the control of a state machine that periodically invokes pause control states to pause the execution of an operator in response to a violation of a service level agreement specifying an operating condition threshold within the distributed computing system. Partitions of input data are formed that are worked on independently within the distributed computing system. A set of data batches associated with the input data is processed. Data partition control states to process the partitions associated with the set of data batches are specified. Key control states to process a set of keys associated with a data partition of the partitions are defined.

摘要： A distributed computing system includes a memory storing execution state collected prior to an operator pause state. A controller modifies, during the operator pause state, characteristics of the distributed computing system. The controller invokes execution of the operator after the pause state such that the operator accesses the execution state to complete an operation.

摘要： A software facility that analyzes consumer interactions with one or more marketing campaigns and the results of those interactions to generate a cross-media or cross-channel attribution model representing the true impact of marketing resource allocation decisions is provided. The facility collects, from a plurality of sources, information representing consumer interactions with marketing campaigns and any results of those interactions. The facility aggregates the information to assess or determine the behavior of consumers with respect to different marketing campaigns and marketing channels. The facility analyzes the information according to varying depths or levels of channel granularity to generate models representative of the true impact of resources allocated to each channel or sub-channel on the performance or effectiveness of the marketing campaign. The facility or other processes may use the generated models to inform future marketing resource allocation decisions.

摘要： A downhole tool (100) including an open loop cooling system (110) having a pressurized container (120) disposed within a tool string, and has a refrigerant (122). The cooling system further includes a tank (150) in fluid communication with the pressurized container (120), and a heat exchanger (160) associated with tank (150), where the heat exchanger exchanges heat between the refrigerant (122) and a downhole payload (164). The cooling system further includes a low pressure apparatus that creates a low pressure region proximate the pressurized container. The low pressure apparatus can include a venturi (180). The venturi has a drilling mud passage (188) therethrough, and drilling mud flowing through a convergence (186) creates a low pressure adjacent the tank (150).

摘要： Systems, methods, and other embodiments associated with hybrid optimization strategies in automatic SQL tuning are described. One example method includes receiving a first (e.g., cost-based) execution plan for a user structured query language statement (User SQL) from a first (e.g., cost-based) optimizer. The example method may also include receiving a second (e.g., rules-based) execution plan for the User SQL from a second, different (e.g., rules-based) query optimizer. The method may include identifying a preferred execution plan based on data produced by test executing the execution plans in a reproduced execution environment that reproduces at least a portion of an execution environment in which the user SQL runs. The method may also include controlling a database to execute the User SQL using the preferred execution plan.

摘要： A database system providing methodology for execution of functions in queries requesting data from markup language documents is described. In one embodiment, for example, a method is described for executing a function in a query requesting data from a markup language document stored in a database, the markup language document organized hierarchically into nodes, the method comprises steps of: receiving the query requesting data from the markup language document, the query including a function to be executed during execution of the query; determining nodes of the markup language document satisfying the query; deriving values of the nodes of the markup language document; and executing the function with the derived values and the nodes of the markup language document.
