System and method for processing high-concurrency data request

Abstract

The invention belongs to the technical field of electronic commerce, and in particular relates to a system and a method for processing a high-concurrency data request. A main body of the system provided by the invention is divided into three parts, namely, a load balancing layer, an arbitration application unit and a goods deduction processing unit, wherein the load balancing layer is used for equally distributing a great amount of client requests to arbitration applications at a rear end; the arbitration application unit is used for receiving user requests which are distributed by the load balancing layer, carrying out qualification judgment, merging and recombining the user requests, and then transmitting to the goods deduction processing unit to carry out deduction processing of goods; the goods deduction processing unit is used for receiving goods deduction requests from the arbitration applications, and carrying out inventory quantity deduction on second-kill goods. By virtue of a single-thread batch processing manner, the bottleneck of a database system caused by multi-thread high concurrency is avoided; meanwhile, high business handling capability is reserved; the cost of system resources is also reduced as low as possible.

Description

technical field [0001] The invention belongs to the technical field of electronic commerce, and in particular relates to a system and method for processing highly concurrent data requests. Background technique [0002] The seckill business has the characteristics of few types of products and a huge number of visits in a short period of time, and users have very strict requirements on the response time of the seckill system. The traditional e-commerce architecture can only meet the huge user visits by increasing the horizontal expansion of the application server. However, due to the single type of products that need to be deducted, the excessive concurrent requests for flash sales will be on the records of individual products in the database. A large number of operation locks are generated, which creates a serious bottleneck in the database, greatly reduces the user's spike response time, and even causes the system to be paralyzed for a short time.
