Abstract

The invention provides a database upgrading method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: obtaining new version data of meta-information; writing the new version data into a data record corresponding to the meta-information in the database, wherein the data record includes old version data corresponding to the meta-information; when the new version data is written into the data record, responding to data operation for the metadata according to the old version data in the data record, and synchronously updating a resultof the data operation to the new version data in the data record; and when writing of the new version data is completed, responding to data operation for the meta-information according to the new version data in the data record. The service can be provided uninterruptedly in the updating period of the database.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a database upgrading method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Database (Database) is the data carrier of various services in the Internet. The types of Internet services emerge in endlessly, and the data volume of each service is increasing, which makes the volume of the database more and more large, which brings difficulties to the smooth upgrade of the database. . [0003] In related technologies, when updating data in a database, in order to ensure data consistency, it is necessary to suspend the operation of writing data in the database, and correspondingly, the database stops providing external services. However, due to the large number of user groups that the database is oriented to, and the time zones where the user groups are located are diverse, once the database stops providing external services during t...
