Abstract: Syntax parsing on a SQL statement is performed to determine whether an extended syntax identifier exists in the SQL statement, where the extended syntax identifier indicates a target computing service for the SQL statement. It is determined that the extended syntax identifier exists in the SQL statement. A computing service description statement in a first statement format is generated based on the SQL statement, where the first statement format is a statement format that can be recognized by a target computing framework. The computing service description statement is submitted to the target computing framework. Data queried by the SQL statement is invoked, in the target computing framework based on the computing service description statement, to perform target computation, where the SQL statement includes a computing element needed by the target computing service.

Abstract: A search request sent by a user is received to obtain one or more query words included in the search request. Historical operating information relating to a data object in a search result corresponding to the query words is conducted statistics. An attribute of the data object is selected as a specified attribute to generate a probability distribution model of the attribute value on the specified attribute of the data object. A respective probability corresponding to the attribute value of each data object on the specific attribute in the research result corresponding to the search request sent by the current user is calculated by using the probability distribution model. The output rank of the data objects in the search result is adjusted by using the probability. The present techniques improve reasonability of displaying the data objects in the search result and provide more accurate result.

Abstract: A method for adjusting a number of logical threads for a component including acquiring a plurality of logical threads that is callable by a component; determining a load state of each logical thread according to a utilization rate of a data processing queue corresponding to each logical thread, the load state including a normal load state and an abnormal load state; determining, according to the load states of the logical threads of the component, whether the number of logical threads of the component needs to be adjusted; and adjusting the number of logical threads of the component according to the determination result if the number of logical threads of the component needs to be adjusted. By using the method and the apparatus, the utilization rate of resources is improved while ensuring real-time calculation of data.
