We have built openGauss,an enterprise-grade open-source database system.openGauss has fulfilled its de-sign goal of high performance,high availability,high security,and high intelligence.For high performance,it leverages NUMA(non-uniform memory access)-aware data access among multiple cores to enable efficient concurrent transaction processing,and symmetric multi-processing to make use of parallel processing resources adaptively.Moreover,memory-op-timized tables(MOTs)are designed to put everything in memory.For high availability,a three-tier pooling architecture that shares storage among the master and standby instances is proposed to achieve availability at 99.99％,containing both a distributed memory service(DMS)and a distributed storage service(DSS).For high security,it is a fully encrypted database with safe storage features,efficient complex querying,and tamper-proof.For high intelligence,an AI-based opti-mizer in the kernel and a self-driving platform named DBMind are demonstrated to achieve better performance and greater user-friendliness.openGauss has served over 150 enterprises and institutions since its release in 2020.We share the lessons we learned from its development and operation,and our customers.
