    Abstract: Some embodiments provide a microservice component-based database system, to split a database kernel into microservice components that can be enabled and run independently and whose functions are decoupled, and implement flexible database assembly and management. The microservice component can be deployed based on a system resource and a service form. The components can collaborate with each other by using a lightweight communication mechanism. A component manager provides capabilities such as registration and deregistration of a service component, component resource management, component fault tolerance, and component upgrade, to implement dynamic management of the component in a running environment. A job scheduler selects, based on a job submitted by a user, an optimal execution path including a plurality of components, and performs resource management and scheduling in a job execution process, to implement load balancing and high availability.

    Abstract: A method for determining a configuration knob of a database is disclosed, and may be applied to a database management system. In this method, vectorization coding is performed on a query statement, to obtain a target feature vector of the query statement, and then a configuration knob set for determining the database is determined based on two aspects of double-state information: the target feature vector and current status information of the database (101). The configuration knob set is used to execute N query statements. The configuration knob of the database (101) may be dynamically determined based on the query statement and the current status information of the database (101), so that good performance of the database (101) in a case of different workload requirements, for example, performance in aspects of a delay and a throughput, can be ensured.

    Abstract: A method, apparatus, and terminal for obtaining a route are provided, including techniques and related apparatus for: obtaining, by a terminal, a first moment at which a signal in the terminal disappears and first location information of the terminal at the first moment, and performing dead reckoning starting from the first moment; obtaining, by the terminal, a second moment at which a user sends a distress signal and second location information of the terminal at the second moment, and ending the dead reckoning, to obtain a first dead reckoning curve; and determining, by the terminal, a track of a traveled route based on the first moment, the second moment, the second location information, the first dead reckoning curve, and each moment between the first moment and the second moment.

    Abstract: A cardinality estimation method and an apparatus are provided. The method includes: selecting a target model type from a plurality of model types based on a target distribution feature and mapping relationship information, where the mapping relationship information includes a mapping relationship between the plurality of model types and a predicted distribution feature, and the target distribution feature is extracted from sample data collected based on an analysis instruction; and obtaining, based on the target model type, a target model corresponding to the target model type, where the target model is used to perform cardinality estimation on a query instruction of a database.
