Problems solved by technology

At present, most indexes are synchronized to a single-point server, and the user's query efficiency is low, and there is no corresponding fault-tolerant processing and recovery mechanism, so the risk is relatively high

Embodiment Construction

[0012] refer to figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the remote multi-point file index synchronization system of the present invention. The remote multi-point file index synchronization system may include multiple index servers, where each index server is placed in a different physical location according to user needs. In this preferred embodiment, index server 1 and index server 2 are used as examples for introduction , the index server 1 and index server 2 can be placed in China, the United States and other regions. The remote multi-point file index synchronization system also includes a synchronization server 4 and a database 6 . The index server 1 and the index server 2 are respectively connected to the synchronization server 4 through the internal network 3 . The synchronization server 4 is also connected to a database 6 via a connection 5 . The connection 5 is a database connection, such as Open Database Connectivity (ODBC), o...

Abstract

The invention provides a remote multi-point file index synchronization system, which includes: an export module, a creation module and a synchronization module. The present invention also provides a remote multi-point file index synchronization method, which includes: exporting a file record in a specific format from a database; remotely controlling multiple index servers to create an index for the file record in a specific format; synchronizing the index, that is, updating the multiple the original index in each index server, and merge the newly created index into the updated original index. The remote multi-point file index synchronization system and method provided by the present invention can perform index synchronization for multiple points, provide real-time backup and error recovery processing functions, and have better security performance, thereby providing better retrieval efficiency.

Description

【Technical field】 [0001] The invention relates to a remote multi-point file index synchronization system and method. 【Background technique】 [0002] Indexes are used to quickly find certain records with specific values, such as MySOL indexes, which are all stored in the form of B-trees. If there is no index, MySOL must scan all the records of the entire table from the first record when executing a query until a record that meets the requirements is found. The more data in the table, the higher the cost of the query operation. If an index has been created on the column used as the search condition, MySOL can quickly get the location of the target record without scanning any records. If there are 1000 records in the table, searching the records through the index is at least 100 times faster than scanning the records sequentially. Webster's Dictionary describes an "index" as a serialized arrangement of material, which is a large, ever-growing, organized collection of web page...
