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.

Solution for implementing computing service based on structured query language statement

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.

Component logical threads quantity adjustment method and device
