摘要
近些年电子商务高速发展,传统零售业受到巨大冲击,转型O2O为大势所趋。零售O2O融合了线上线下交易场景,需要一个高并发高可用的系统支撑。本文针对零售O2O交易系统,分别从系统架构设计和业务逻辑实现2方面,研究并提出一系列高并发、高可用策略。从架构设计的角度,提出并介绍分层解耦、集群负载均衡、混合数据存储、静态化分离的策略;从业务实现的角度,提出并介绍订单库存分区缓存、订单事务降级、库存一致性、请求限号排队的策略。实验证明,这些策略可以有效提升系统的并发性、可用性,具有重要实践参考价值。
With the fast development of e-commerce in recent years,traditional retail industry declines. Retail industry has a trend to change into O2 O mode. Retail O2 O combines online scenario with offline scenario. It needs a high concurrency and high availability supporting system. We studied and proposed a series of system strategies to build a high concurrency and high availability retail O2 O system,both in architecture design and business implementation. On architecture design aspect,we proposed the strategies including： hierarchical decoupling,clustering load balance,hybrid data storage,static separation. On business implementation aspect,we proposed the strategies including： order-stock caching,transaction degrade,stock consistency,request queueing. Experiment shows all of the strategies are very effective and are of practical reference value.
