The invention relates to a high concurrency and fast response type second-killing inventory precise deduction method, a device and a system. According to the invention, the problem in the prior art that the inventory is insufficiently or additionally deducted in a high-concurrency and large-flow user panic-buying scene. The method comprises the following steps of initializing and generating a corresponding number of tokens with unique marked values according to the inventory number of a second-killing activity; storing the tokens in a Redis cache queue; if one token is obtained from the Rediscache queue according to the purchasing request of a user, inserting the information of the user into an order database; if the information of the user is successfully inserted, determining that the deduction of the inventory is successfully done, wherein the information of the user comprises the user identification information and the user ordering information; if the information of the user is failed to be inserted, returning the obtained token to the Redis cache queue.
Description
technical field [0001] The present invention relates to the field of computer technology and software, in particular to a method, device and system for precise deduction of flash sale inventory with high concurrency and fast response. Background technique [0002] Flash sales promotions have increasingly become an important means for e-commerce companies to attract user registration and increase user activity. Among them, whether the seckill inventory is accurately deducted is a key indicator to measure the reliable operation of the seckill system. Before the seckill activity starts, a seckill promotion activity is usually created according to the product ID (hereinafter referred to as "SKUID") (a seckill promotion activity corresponds to a promotion ID, hereinafter referred to as "PromoID"), and the seckill start and end time, seckill price, seckill Inventory and other information. [0003] In the existing technology, the initial storage and deduction methods of the secki...
