Abstract

The invention provides a distributed type database inquiry method. The method includes the steps of retrieving an inquiry cache area according to a received inquiry statement, wherein historical execution information is stored in the inquiry cache area; conducting inquiry according to the historical execution information when the historical execution information corresponding to the inquiry statement is retrieved. Part of the generation process of an execution tree can be omitted in the inquiry process of a distributed type database, and therefore the inquiry time delay of the distributed typedatabase is reduced and the concurrent degree is improved.

Description

technical field [0001] The invention relates to the field of distributed databases, in particular to a distributed database query method, device and management system. Background technique [0002] With the maturity of traditional database technology and the rapid development of Internet applications, database applications have generally appeared on the Internet. However, the traditional centralized database system also shows its shortcomings—the use of centralized management will inevitably cause performance bottlenecks, and the single improvement of hardware performance can no longer meet the current needs of large data volumes and high concurrent query writing on the Internet , At the same time, a large amount of hardware maintenance and upgrade costs will be generated. In addition, the centralized management of databases often results in multi-database associations. Once a certain database crashes, it will cause the entire system to crash. Therefore, the development of...
