数据库选型必须翻越的“成见大山”

Core Viewpoint - The article discusses the growing trend of adopting distributed databases, highlighting both their advantages and limitations in various business contexts, emphasizing the need for a tailored approach to database selection based on specific business requirements [1][19]. Group 1: Advantages of Distributed Databases - Distributed databases are praised for their horizontal scalability, enabling them to handle massive data volumes and high concurrency, making them suitable for applications like e-commerce and social media [10][13]. - The increasing demand for distributed databases has been fueled by the rapid growth of internet companies and their business models, which have set a high standard for data management [9][10]. Group 2: Limitations of Distributed Databases - In traditional enterprise scenarios, distributed databases may not perform as well, presenting challenges such as higher operational complexity, increased costs, and potential performance issues due to node communication delays [15][16]. - A notable case illustrates that while a bank improved performance and scalability by implementing a distributed database, it faced significantly higher operational costs, including manpower and infrastructure expenses [18]. Group 3: Appropriate Use Cases for Database Selection - Businesses should first identify their specific needs and pain points before choosing a database solution, as distributed databases are best suited for high-traffic, large-scale applications [19][21]. - For complex business calculations and scenarios with concentrated data hotspots, centralized databases may be more effective, as seen in applications like ticketing systems and hospital management [21]. Group 4: Misconceptions About Distributed Databases - Many perceived "distributed scenarios" do not necessitate a distributed database; for instance, multi-tenant applications can often be better served by centralized databases that support multi-tenancy [27][29]. - Some organizations mistakenly include distributed databases in procurement specifications simply due to their popularity, leading to suboptimal deployment and performance outcomes [31][33]. Group 5: Tailored Solutions from JinCang Database - JinCang Database offers a diverse product line that includes both centralized and distributed databases, catering to various business needs [35]. - For distributed application requirements, JinCang can effectively support microservices architecture, allowing for optimized database design tailored to specific service needs [36][39]. - The database also provides multi-tenant solutions to maximize resource utilization and reduce costs, addressing the needs of different departments within an organization [42][55]. - JinCang's offerings include high-availability solutions for large enterprises, as well as true distributed database solutions for ultra-large applications requiring high concurrency and fault tolerance [59][64].
