Highly-available high-performance digital sequence generating method and system

Abstract

The invention provides a highly-available high-performance digital sequence generating method and system. Final digital sequence generation logics are all placed in a client needless of a service end;and digital sequence generation is highly available and high-performance. The method comprises the steps that 1) the client obtains a digital sequence from a memory queue according to a digital sequence request, if there is the digital sequence in the memory queue, the digital sequence is returned directly, and if there is no digital sequence in the memory queue, a step 2) is turned to; 2) the client calls a bottom sequence generator to generate a bottom sequence; 3) the client generates multiple digital sequences on the basis of the bottom sequence; and 4) the digital sequence in the first place is returned, and the other digital sequences are stored in the memory queue, so that the digital sequence can be obtained according to subsequent digital sequence requests.

Description

technical field [0001] The invention relates to the field of computer technology and software, in particular to a method and system for generating digital sequences with high availability and high performance. Background technique [0002] With the continuous development of computer technology, it is often necessary to generate a unique number sequence in various business scenarios, such as express delivery number, commodity order number in the e-commerce field, or sub-database sub-table to ensure a unique digital primary key of the data table, etc. Each business system will rely heavily on this kind of number sequence generation method. If the number sequence generation efficiency is low, it will directly affect the efficiency of the business system. If the number sequence generation is abnormal, it will directly cause the business system to be unavailable. [0003] The generation method of the digital sequence in the prior art is roughly as follows: [0004] 1. The digita...

AI Technical Summary

Problems solved by technology

[0008] 1) When the digital sequence client requests to generate a digital sequence, it needs to request the server first, and then the server requests the database, and there are two network request overheads;

[0009] 2) The digital sequence server needs to deploy multiple servers to meet the high availability requirements of sequence generation, so more hardware resources are required
