面向电商系统的分布式数据库架构
摘 要
随着电子商务的迅猛发展，电商系统面临着海量数据处理、高并发访问和业务连续性的挑战，传统集中式数据库架构难以满足其需求。为此，本文研究面向电商系统的分布式数据库架构，旨在构建一种能够高效处理大规模数据、支持高并发事务且具备良好扩展性的数据库架构。通过分析电商系统的特点与需求，结合分布式计算理论，提出基于分片、复制及一致性协议的分布式数据库架构设计方案。该方案采用水平分片技术将数据分散存储于多个节点，利用复制机制提高数据可用性和读取性能，并引入Paxos等一致性协议确保数据一致性。实验结果表明，所设计的架构在处理大规模数据时具有较高的吞吐量和较低的延迟，在应对高并发场景下表现出良好的稳定性和可扩展性。

Abstract
With the rapid development of e-commerce, the e-commerce system is faced with the challenges of massive data processing, high concurrent access and business continuity, and the traditional centralized database architecture is difficult to meet its needs. To this end, this paper studies the distributed database architecture for the e-commerce system, aiming to build a database architecture that can efficiently handle large-scale data, support high concurrent transactions and has good scalability. By analyzing the characteristics and requirements of the e-commerce system and combining with the distributed computing theory, the distributed database architecture design scheme based on fragmentation, replication and consistency protocol is proposed. This scheme uses horizontal sharding technology to store data in multiple nodes, uses the replication mechanism to improve data availability and read performance, and introduces a consistency protocol such as Paxos to ensure data consistency. Experimental results show that the designed architecture has high throughput and low latency when processing large-scale data, and shows good stability and scalability against high concurrency scenarios.
