Method and system for generating digital sequences with high availability and high performance

Abstract

The present invention provides a high-availability and high-performance digital sequence generation method and system, which can eliminate the need for a server, and make the final digital sequence generation logic all placed on the client; and can ensure high availability and high performance of digital sequence generation . The method includes: step 1: the client obtains the number sequence from the memory queue according to the number sequence request, and returns the number sequence directly if there is a number sequence in the memory queue, and continues to execute if there is no number sequence in the memory queue Step 2; Step 2: the client invokes the underlying sequence generator to generate the underlying sequence; Step 3: the client generates several digital sequences based on the underlying sequence; Step 4: returns the number sequence ranked first, And save the remaining number sequences in the memory queue, so that the number sequences can be obtained in time for subsequent number 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
