Problems solved by technology

Due to the inconsistency of the machine time, the time of each server needs to be synchronized, which may cause the server time to roll back
If some IDs happen to be generated before the rollback, and after the time rolls back, the generated IDs may be duplicated

Abstract

The embodiment of the invention discloses an identification number generation method and device, computer equipment and a storage medium, and the method comprises the following steps: obtaining historical queue information which is used for recording a timestamp code and a sequence code of a generated identification number; determining whether a preset first identification number meets a preset repetition condition according to the historical queue information, the first identification number being an identification number generated by time callback; and when the first identification number meets the repetition condition, generating a second identification number according to the historical queue information. A used timestamp and a used sequence code are recorded by setting historical queue information; whether the identification number is repeated or not is determined according to the historical queue when the identification number is generated by time callback, and when the identification number is repeated, the new identification number is generated by using the sequence code which is not used before according to the historical queue information, so that the generated identification number is effectively ensured not to be repeated.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a method, device, computer equipment and storage medium for generating an identification number. Background technique [0002] In a distributed system, it is often necessary to define corresponding data using a globally unique ID (GUID). In order to meet Twitter’s request for tens of thousands of messages per second, each message must be assigned a unique ID, and these IDs also need some approximate order (to facilitate client sorting), and the IDs generated by different machines in a distributed system must be Different, in this regard, Twitter has developed a snowflake ID generation scheme. The core idea is: generate a long ID, use 41 bits (bit) as the timestamp (unit: milliseconds), 10 bits as the machine number, and 12 bits as the serial code . Except that the highest bit (bit) is marked as unavailable, the other three groups of bit occupants can be fl...
