Abstract

The present application provides a method and device for generating a database record master key, an electronic device, a distributed issuer for a database record master key, and a non-transitory computer-readable storage medium. The method includes: obtaining the current system time, generating a database record primary key; recording the system time when the database record primary key is newly generated, and making the system time according to the system time recorded when the database record primary key under the same time slice was generated last time. comparing, determining whether a clock callback under the same time slice occurs; and based on the determined result, generating a new primary key of the database record, the primary key of the database record includes time slice data, and the time slice data occupies the database record Multiple data bits of the primary key and a data toggle every time a clock callback occurs.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for generating a database record master key, an electronic device, a distributed issuer for a database record master key, and a non-transitory computer-readable storage medium. Background technique [0002] A record primary key is a unique identifier that identifies each record in a database system. At present, the mainstream database record primary key (also called unique ID) generation strategy is to use serial numbers, that is, to generate long integer record primary keys in a sequentially increasing manner. However, in the case of multiple computer rooms or multiple database instances, it is difficult for the record primary key generated using the serial number to meet the uniqueness requirement, because the databases of different instances may generate exactly the same integer value. In order to solve this problem, an independent system (usua...
