Problems solved by technology

[0003] In a system, the in-memory database and the relational database generally coexist at the same time, and the new data is generally stored in the in-memory database first, and after a preset time, the new data will be transferred from the in-memory database to the relational database However, if the new data stored in the memory database is lost due to system power failure before the preset time, this will affect the transfer synchronization of the new data, resulting in the existing new data transfer efficiency still lower

Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0044] The signature-based power grid monitoring system memory database relational database synchronization method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 11 communicates with the server 12 through the network. The server 12 receives the data sent by the terminal 11 as new data, and the server 12 writes the new data into the data cache area of ​​the memory database and marks the new data; The mapping relationship is to write the newly added data with the tag into the cache file of the rel...

Abstract

The invention relates to a power grid monitoring system memory bank relation library synchronization method and device based on feature marking, computer equipment and a storage medium. The method comprises the steps that newly-added data is written into a data cache region of a memory database and marked; writing the newly added data with the mark into a cache file of a relational database according to a mapping relationship between the data cache region and the cache file of the relational database; and writing the newly added data temporarily stored in the cache file into the relational database according to the mark. According to the method, the newly-added data is marked, and the newly-added data temporarily stored in the cache file is written into the relational database, so that the problem that the memory database needs to synchronize the data after a period of time is solved. The system data can be synchronized quickly; the efficiency of data synchronization between the memory banks and the relation banks of the power grid monitoring system based on the feature marks is improved.

Description

technical field [0001] The present application relates to the technical field of power grid monitoring, and in particular to a method, device, computer equipment and storage medium for synchronizing memory databases and relational databases of a power grid monitoring system based on signatures. Background technique [0002] In-memory databases and relational databases generally exist in power grid monitoring systems; in-memory databases are databases that store data in memory and operate directly. Features, save data in memory; relational database refers to a database that organizes, stores and manages data according to a certain data structure and model, and a database built using a relational model is called a relational database. [0003] In a system, the in-memory database and the relational database generally coexist at the same time, and the new data is generally stored in the in-memory database first, and after a preset time, the new data will be transferred from the ...
