Group 1 - The core viewpoint of the articles emphasizes the importance of database performance and reliability in today's data-driven business environment, highlighting GBase 8s as a mature and stable domestic database system with an optimized SSC cluster architecture that significantly enhances performance and availability [1][3]. - GBase 8s SSC cluster operates by minimizing network data transmission between the main and slave nodes, only sending network heartbeat and current logical log position information, which reduces network latency and enhances synchronization performance [1][8]. - In a scenario with a single slave node, the theoretical maximum network throughput between the main and slave nodes is approximately 3.5 MB/s, with a performance of 1 million tpmc at 400 concurrent users [1][2]. Group 2 - The SSC cluster architecture allows multiple database instances to access and operate on the same database simultaneously, featuring high availability, high performance, and load balancing, along with automatic failover and rejoining capabilities [3][4]. - In scenarios where the SSC slave node supports updates, the network throughput can reach 248.9 MB/s with a performance of 1 million tpmc for the new order business in TPCC [2]. - The SSC cluster's operational principle involves the main node sending the current Log Sequence Number (LSN) to the slave node, which then retrieves the updated logical logs from shared storage, thus avoiding the need to transfer logical log files between nodes [8][9].
