Object number generating method and device

Abstract

The invention provides an object number generating method and an object number generating device. The object number generating method and the object number generating device, on the one hand, contribute to improving the discount coupon number generating efficiency and the reliability, and on the other hand, facilitate avoiding the problem of single point of failure. The object number generating method comprises the following steps: acquiring the current number in a designated memory database; regarding the memory database as a single-threaded memory database; according to the preset step length, performing atomic increase based on the current number to obtain the generated number; outputting the generated number and saving the number to the designated memory database.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating object numbers. Background technique [0002] With the rapid development of e-commerce, online shopping has become a craze, and coupons, as one of the sales promotion methods of merchants, have also moved from traditional paper coupons to electronic coupons. With the development of business, while the number of electronic coupons is increasing, higher requirements are placed on the speed of coupon issuance. Each coupon corresponds to a unique coupon number, which requires the system to be fast and without duplication The implementation of coupon number generation. [0003] The way to generate the existing electronic coupon number is: first obtain the current coupon number by querying the coupon database table, and add 1 on the basis of the current coupon number, and then use the added value as the new Output the coupon number, and save the i...

Problems solved by technology

[0003] The way to generate the existing electronic coupon number is: first obtain the current coupon number by querying the coupon database table, and add 1 on the basis of the current coupon number, and then use the added value as the new Output the coupon number, and save the incremented value to the coupon database table; there are two problems with this method: performance problem and single point problem

[0004] Performance problem: The existing method of generating coupon numbers uses SQL database to serve the generation of coupon numbers, and the coupon database table needs to be operated every time, which means that the generation of coupon numbers needs to be persisted with the data of coupon subject information Competing for limited database resources; the necessary data writing operations for each coupon issuance, while adding additional database read and write operations related to coupon numbers, which will inevitably lead to low efficiency in producing coupon numbers; in addition, Due to the problem of multi-threaded concurrent synchronization of the database, the database will fail, which will reduce the reliability of generating coupon numbers

[0005] Single-point problem: The existing coupon number generation method relies on a single database instance, the computer where the database instance is located and its network environment. In this single deployment mode, the coupon-related database instance, the computer where the database instance is located and its network environment It is inevitable that various problems may occur and cannot be accessed normally, so it is impossible to generate a new coupon number, which causes a single point of failure
