Chan Ye Xin Xi Wang·2025-12-16 01:25Core Insights - The role of in-memory databases has fundamentally shifted from being an "auxiliary tool" focused on caching and performance acceleration to becoming a "key strategic infrastructure" that supports core business systems in finance and telecommunications [1][7]. Industry Overview - Database management systems are essential software for organizing, storing, and managing data, serving as the backbone for IT core systems in the information and big data era [1]. - In-memory databases store data primarily in RAM, achieving read/write speeds that are tens to hundreds of times faster than traditional disk databases, making them suitable for real-time applications [3][1]. Market Size - The market size of China's in-memory database industry is projected to reach approximately 10.104 billion yuan in 2024, representing a year-on-year growth of 20.29% [1][7]. Key Companies - Major players in the in-memory database sector include Huawei's GaussDB, Ant Group's OceanBase, and Tencent Cloud's TDSQL, which leverage cloud-native architectures and distributed technologies [8]. - Traditional database vendors like Dameng Data and Kylin Software are also significant, with their solutions supporting high-performance real-time memory computing [8][10]. Industry Development Trends 1. Technological Evolution: In-memory databases are integrating AI, cloud computing, and distributed architectures, leading to a new paradigm of "intelligent in-memory computing" [12]. 2. Application Expansion: In-memory databases are increasingly tailored for specific verticals such as finance and telecommunications, enhancing their adaptability to real-time requirements [13]. 3. Domestic Ecosystem Construction: Under the influence of domestic innovation policies, local in-memory database vendors are accelerating the establishment of a comprehensive ecosystem that includes chips, operating systems, databases, and applications [14][15].
