GoldenDB is a self-developed distributed database system, consisting of four core modules: computing nodes, data nodes, global transaction managers, and management nodes. The periphery includes import and export modules, as well as related backup, recovery, and other operation and maintenance tools. The entire system adopts a high reliability design with no single point of failure, and the computing nodes are deployed in a stateless multi node manner. The data cluster is composed of multiple security shards, with each security shard group having multiple primary and backup data nodes deployed on multiple machines, and the global transaction manager having multiple primary and backup machines deployed on multiple machines. Supports multi cluster and dynamic scaling, with each cluster consisting of multiple security shard groups. Each security shard group contains database nodes with primary and backup replication relationships, which can dynamically expand the number of security shard groups within the cluster and increase the number of clusters. Support distributed transactions across multiple nodes through a global transaction manager to ensure data consistency. Compatible with SQL92, SQL99, and SQL2003 standard syntax, fully compatible with MySQL syntax, and compatible with commonly used Oracle and DB2 syntax.
