Abstract

The present invention provides a distributed database query method, including: searching in the query buffer area according to the received query statement, wherein the query buffer area stores historical execution information; In the case of execution information, query based on the historical execution information. This enables the distributed database to save part of the execution tree generation process during the query process, thereby reducing the time delay of the distributed database query and improving the concurrency.

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...
