openGauss社区正式发布业界首个开源多写数据库oGRAC

Core Insights - The openGauss community has launched the industry's first open-source multi-write database architecture, oGRAC, marking a significant milestone in the database industry [1][3]. Group 1: Technical Breakthroughs - The oGRAC architecture aims to provide high availability and linear scalability while supporting multi-node read and write operations [4]. - Key innovations include an in-place update engine that utilizes undo-based consistency snapshot pages, achieving page-level MVCC (Multi-Version Concurrency Control) and significantly enhancing high-concurrency data access [4]. - In testing environments, oGRAC has demonstrated a throughput capacity of 3.5 million tpmC, positioning it as a leader in performance within the industry [4]. Group 2: High Availability and Resource Efficiency - The database core supports incremental checkpoints and global cluster management, ensuring a recovery point objective (RPO) of 0, which guarantees zero data loss [5]. - The architecture introduces a distributed caching mechanism and distributed lock service, achieving a linear scalability ratio of 0.82, allowing for over 50% savings in computing and storage resources compared to traditional solutions [5]. Group 3: Open Source Ecosystem - The openGauss community emphasizes the importance of open source as a driving force for technological innovation and industry progress, inviting global developers and partners to collaborate on the exploration and application of multi-write databases [6]. - The release of oGRAC provides a new, open, and reliable foundational software choice for industries such as finance, telecommunications, energy, and the internet, which have stringent requirements for data consistency and high availability [6].
