Problems solved by technology

[0003] Among them, 1. UUID calculation rules guarantee the uniqueness of the global system, but UUID has poor generation performance, untraceability, irreversible solution, and disorder. If UUID is used as the primary key of the database, it will cause database writing problems
[0004] 2. The implementation of the database method is generally realized by generating a primary key from the data and setting a specific primary key step size. This implementation scheme has poor performance and poor horizontal expansion capabilities, and at the same time relies on the database, which increases personnel maintenance costs
In a distributed environment with rapid development and high performance requirements, it is impossible to meet user needs

Abstract

The method is suitable for the technical field of distributed systems. The invention provides a unique key generation method, device and terminal equipment, The method comprises the following steps of: Obtaining data to be generated, correspondingly generating a service instance code according to the service instance sequence of the to-be-generated data, correspondingly generating a year, a week,weekdays and a second according to actual time, correspondingly generating a serial number, an expansion bit and a version according to a preset rule, synthesizing the generated field into a unique key according to a unique key basic data structure, and labeling the unique key in the to-be-generated data; Wherein the generation field comprises service instance codes, years, weeks, weekdays and seconds, serial numbers, extension bits and versions. The method can ensure that the unique key data is not repeated in a single-machine scene, and meets the basic requirements of distributed global uniqueness, orderliness, inverse solvability, high performance, expandability, readability and the like.

Description

technical field [0001] The invention belongs to the technical field of distributed systems, and in particular relates to a unique key generation method, device and terminal equipment. Background technique [0002] In a distributed environment, the processing method of generating a unique key is generally realized through a universally unique identifier (UUID, Universally Unique Identifier) ​​calculation rule or a database generation method. [0003] Among them, 1. UUID calculation rules guarantee the uniqueness of the global system, but UUID has poor generation performance, untraceability, irreversible solution, and disorder. If UUID is used as the primary key of the database, it will cause database writing problems. [0004] 2. The implementation of the database method is generally achieved by generating a primary key from the data and setting a specific primary key step size. This implementation scheme has poor performance and poor horizontal expansion capabilities, and it...
