Data distributed storage method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a data distributed storage method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining database building conditions, executing corresponding database building instructions according to the database building conditions, and building a plurality of main databases and a plurality of standby databases correspondingto the main databases; determining a target main database of a database table to be established from the main database, and determining a target standby database corresponding to the target main database from the standby databases; acquiring a database table establishing condition, executing a corresponding database table establishing instruction according to the database table establishing condition, and establishing database tables in the target main database and the target standby database respectively; obtaining to-be-stored data, and storing the to-be-stored data to a database table in the target main database; and synchronizing the to-be-stored data stored on the database table in the target main database to the database table in the target standby database based on a preset data consistency algorithm.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data distributed storage method, device, electronic equipment and storage medium. Background technique [0002] At present, databases have become the carrier of social informatization development, domestic databases are booming, and database commercialization is becoming more and more mature. Against this background, various Internet giants have started to develop their own distributed domestic databases based on business characteristics and industry needs. One of the key technologies is how to implement distributed data storage at the bottom layer of the database, so that data can be evenly distributed to multiple storage units, and fast database read and write requests can be realized. [0003] Among related technologies, represented by oceanbase and tidb, the distributed structured data storage based on the theoretical basis of Google's bigtable paper is realize...

Problems solved by technology

[0003] Among related technologies, represented by oceanbase and tidb, the distributed structured data storage based on the theoretical basis of Google's bigtable paper is realized. In the development and design of domestic databases, the theoretical basis of bigtable paper is used to realize sparse, distributed, Persistent storage. At the same time, the theory of the bigtable paper is based on GFS, which has a high technical threshold, and the implementation is complicated and the cycle is very long.
