Problems solved by technology

The reason is that the first query of data in a large-scale data table needs to load the data from the hard disk to the memory, and the loading speed is slow, which leads to the problem of slow data query for the first query of a large-scale data table

Abstract

One embodiment of the invention provides a database data processing method, device and system and relates to the field of database engine field. The invention can increase the processing speed duringdata processing. The program is applied to a data processing system comprising a data preloading interface and a database management engine. The data preloading interface and the database management engine are deployed on the same network device or deployed on different network devices respectively. The method comprises following steps: the data preload interface sends a preset type of command tothe database management engine; the database management engine processes target memory according to a preset type of command, wherein the target memory is the memory corresponding to the preset type of command. This application can be applied to open source database management engine to process data.

Description

technical field [0001] The present application relates to the field of database management engines, in particular to a database data processing method, device and system. Background technique [0002] Currently, the open source database management engine can load data using memory mapping. The memory mapping mechanism is similar to the virtual memory mechanism, which is a mechanism provided by the operating system to map files on the disk to the memory address space. When the relevant process reads the file, it reads directly from the memory. If a page fault interrupt occurs, the interrupt response function will be responsible for reading the data from the hard disk into the memory. [0003] In the process of implementing the above memory mapping mechanism, the inventor found that at least the following problems existed in the prior art: [0004] When querying the data of a large number of data tables through the open source database management engine, the speed of the fir...
