Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] figure 2 is a schematic structural diagram of a data processing device according to an embodiment of the present invention. Such as figure 2 As shown, the data processing device includes a database connection pool manager 10 and an execution unit 30 .

[0034] The database connection pool manager 10 can manage and use multiple database connection pools in a cluster environment. The multiple database connection pools are used for multiple database nodes of the cluster database system, and corresponding data operations on the database nodes, such as data query operations, can be provided through the connections in the multiple database connection pools. It should be noted that, in this embodiment of the present invention, a database node should be understood as a physical entity such as a database server.

[0035] In the embodiment of the present i...

Abstract

The invention discloses a data processing device which comprises a database connection pool manager and an execution unit. The database connection pool manager comprises an acquiring unit, wherein the acquiring unit is used for executing the following operations of acquiring a mapping relation of database nodes and database connection pools in a cluster database system, wherein the multiple database nodes correspond to at least two database connection pools; acquiring corresponding database connection pools according to the mapping relation and database nodes to be managed; acquiring available database node connection from the acquired database connection pools. The execution unit carries out corresponding database operations on the database nodes to be managed through the acquired database node connection. Correspondingly, the invention further provides a data processing method. By the adoption of the data processing device and the data processing method, connection management of multiple database nodes in the cluster database system can be achieved, and operating performance improvements of all database nodes are facilitated.

Description

technical field [0001] The present invention relates to the technical field of computer data processing, and more specifically, to a data processing method and a data processing device. Background technique [0002] Database connection pool is a technology that uses pooling to manage database connection resources and improve the performance of application systems accessing databases. The main function of the connection pool is responsible for allocating, managing and releasing database connections, which allows an application to reuse an existing database connection instead of re-establishing one. In the prior art, the database connection omission caused by not releasing the database connection is avoided by releasing the database connection whose idle time exceeds the maximum idle time. Using the database connection pool can effectively avoid time-consuming operations such as creating and closing frequent database connections, and can significantly improve the performance ...
