Main server, slave server, index synchronizing system and index synchronizing method

Abstract

The invention provides a main server which is applied to an index synchronizing system. The main server comprises an index changing point recording unit, an index changing information sending unit and an index file sending unit. The index changing point recording unit carries out monitoring on the main server, and when the fact that index files of the main server change and are submitted is monitored, index file changing information is recorded, and the event of the changing of the index files is added to an index changing point queue. The index changing information sending unit checks the index changing point queue at regular time, and sends the index file changing information to a slave server when the event of the changing of the index files is checked. The index file sending unit searches the index files corresponding to index synchronous requests when receiving the index synchronous requests from the slave server, and sends the index files to the slave server. Correspondingly, the invention further provides a slave server, an index synchronizing system and an index synchronizing method. Through the technical scheme of the main server, the slave server, the index synchronizing system and the index synchronizing method, searching efficiency can be improved.

Description

Technical field [0001] The present invention relates to the technical field of indexes, in particular to a master server, a slave server, an index synchronization system and an index synchronization method. Background technique [0002] In the process of enterprise development and growth, the number of users continues to increase, and single-machine search can no longer satisfy the enterprise's search service in terms of performance, usability and stability. [0003] In the prior art, there are currently two main methods for synchronizing index files: [0004] 1. Rsync is a data mirroring backup tool under Unix / Linux-like system, which realizes the index file copy between different servers. [0005] 2. File sharing is adopted, for example, a file system sharing method is adopted, the index file is passed through the file sharing method, and the index server reads the index file through the file system. [0006] There are some shortcomings in the actual application process of the above ...

AI Technical Summary

Problems solved by technology

[0006] The above two solutions have some defects in the actual application process. The first solution needs to configure synchronization scripts on different servers, which is cumbersome to implement and prone to errors. In the second solution, the shared file system will become the bottleneck of the entire system. When the index file When updating frequently, it will cause problems such as blocking
