Data writing method and device and data reading method and device

Abstract

Embodiments of the invention provide a data writing method and device and a data reading method and device. The data writing method comprises the following steps of: when an application process in a target server is started or restarted, obtaining main key configuration information from a database, wherein the main key configuration information at least comprises corresponding relationship among data table identifiers of one or more data tables in the database and/or a target server identifier and real-time main key information; storing the main key configuration information in the target server; obtaining business data to be written into a target data table; determining target main key information corresponding to the business data from the main key configuration information, wherein thetarget main key information at least comprises a target data table identifier and/or the target server business and a business data sequence of the business data; and writing the business data into the target data table by adoption of the target main key information, so as to distinguish the main key information, optimize a composition structure of the main key information, enhancing the timeliness of obtaining the main key information and enhancing the persistent business data writing performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data writing method, a data writing device, a data reading method, and a data reading device. Background technique [0002] With the development of science and technology, computer systems are becoming more and more complex, and the business pressure that needs to be loaded is increasing. The real-time requirements for computer systems to process business data are also increasing. [0003] At present, computer systems are usually deployed with a multi-application server-single database server architecture. A single database server is naturally under great pressure, especially when business pressure suddenly increases and application servers have high concurrency, which seriously affects the computer system. performance. [0004] The traditional database primary key management is a part of the database management system. Due to the performance of the computer system, especiall...
