Identifier generation method and device, equipment and storage medium

Abstract

The invention discloses an identifier generation method and device, equipment and a storage medium, and belongs to the technical field of computers. The method comprises the steps of obtaining a current timestamp in response to an identifier generation request; and determining a target identifier generator from the at least two identifier generators according to the time sequence relationship between the historical timestamp for generating the previous identifier and the current timestamp; based on the target identifier generator, generating an identifier according to the current timestamp, the generator serial number, the equipment identifier and the self-increasing serial number; when a clock callback condition occurs, enabling a identifier generation process to switch the target identifier generator for generating IDs until a clock returns to normal. The generator serial number is the serial number of the target identifier generator in the at least two identifier generators, and theserial numbers of the identifier generators are different. Uniqueness of the generated ID when the target identifier generator is switched is ensured. Reliability of ID generation is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a logo generation method, device, equipment and storage medium. Background technique [0002] Most of today's network services need to use ID (Identity document) to identify various data objects. For example, the account number of the user, the order number of online shopping, and the role number of online games. ID refers to a unique number or string. When a computer device generates an ID, it needs to ensure the uniqueness of the ID. [0003] Currently, computer devices generally use a snowflake algorithm to generate IDs. The ID generated by the snowflake algorithm has a length of 64 bits (binary digit, bit). Among them, the highest bit is always 0, indicating a positive integer; the next 41 bits indicate the cumulative number of milliseconds from the time when the ID is generated to the target time; the next 10 bits indicate the serial number of the device ...

AI Technical Summary

Problems solved by technology

[0004] When the clock is dialed back, the cumulative number of milliseconds and the self-increment sequence in the ID generated by the snowflake algorithm may be repeated, resulting in duplicate generated IDs

The uniqueness of the generated ID cannot be guaranteed, and the reliability of the generated ID is low
