Problems solved by technology

[0003] When the database performs transaction processing, data backup is required so that in the event of a failure, data recovery and restoration can be performed based on the backup files. The existing TiDB database uses archive tapes for data backup, and the IO transmission capacity of archive tapes is weak, while the TiDB database Often the amount of data is large, which makes data backup and restoration time longer, resulting in lower efficiency of database maintenance

Abstract

The invention discloses a TiDB database maintenance method and device, computer equipment and a storage medium. The method comprises the following steps of: acquiring data in a TiDB production librarythrough a TiDB-Binlog cluster component; obtaining a binlog file corresponding to the data in the TiDB production library; synchronizing the binlog file to a TiDB city-wide disaster recovery database; then, a preset timed backup script is adopted; synchronizing the binlog file in the TiDB city-wide disaster recovery database to a flash memory NAS device; when monitoring that the TiDB production library is abnormal, carrying out data recovery processing on the TiDB production library based on the binlog file stored in the flash memory NAS equipment, so that the problem of low backup and recovery speed due to the fact that data in the production library is directly stored in an archiving magnetic tape in a traditional mode is solved, and the maintenance efficiency of the TiDB database is improved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a TiDB database maintenance method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of the economy, more and more enterprises have expanded their business scope and expanded their user groups. Many enterprises have begun to use distributed databases for data storage in order to improve business processing capabilities. TiDB is a An open source distributed relational database with high security, compatible with MySQL protocol and ecology, easy to migrate, and extremely low operation and maintenance costs, has become a relatively popular distributed database. [0003] When the database performs transaction processing, data backup is required so that in the event of a failure, data recovery and restoration can be performed based on the backup files. The existing TiDB database uses archive tapes for data backup, and the IO...
