Abstract

The invention discloses a roll-back method, a device and a system of a non relational database. The method comprises: judging whether operations can not be carried out to a non relational database, if the operations can not be carried out to the non relational database, replacing the original data of the non relational database with the mirror data of a mirror database, and the mirror data are the backup copy of the data of the non relational database before the current time period, modifying the mirror data of the non relational database according to the correct log content before a first time which enables the operations not be carried out to the non relational database in the current time period in a log database. By adopting the roll-back method, the device and the system of the non relational database, the mirror data of the mirror database is enabled to replace the original data in the non relational database, then modification can be carried out on the correct mirror data according to the content of the correct log, and therefore the roll-back function of the non relational database is achieved.

Description

technical field [0001] The present invention relates to the database field, and more specifically, relates to a rollback method, device and system for a non-relational database. Background technique [0002] With the rise of Internet web2.0 websites, ultra-large-scale and high-concurrency purely dynamic web2.0 websites have exposed many insurmountable problems. Therefore, many companies have changed the MySQL open source database in Web2.0 to non-relational The non-relational database has developed very rapidly due to its own characteristics. [0003] Non-relational databases generally refer to a type of database different from relational databases. The data stored in such databases has no fixed schema, and non-relational databases are highly scalable. [0004] However, non-relational data does not provide a rollback function, and when the database is repaired, the recovery time will be very long. Rollback generally refers to the failure of a program update to return to th...
