ZTE has accumulated technical experience in the database field for over 17 years. Since 2002, ZTE has developed its file database, memory database, and distributed database products, and provided database products for the telecommunication industry in large scale. In 2014, it started R&D of the distributed database for the financial industry. The product is independently developed by ZTE and has more than 100 patents.
For banks’ OLTP businesses, ZTE distributed database GoldenDB provides computing and scaling capability that cannot be achieved by traditional stand-alone databases. Its high-availability, high-reliability, and high-flexibility database service can fully satisfy banks’ needs for rapid business upgrading and innovative business deployment.
1)Share Nothing distributed architecture: Computing and storage are separated, and storage nodes provide strong local computing capability. Without single-point failure, it ensures zero data loss and service continuity even in case of equipment faults. It supports unlimited computing performance and storage capacity scale out. It supports visualized monitoring and O&M of ultra-large-scale nodes.
2)Efficient and reliable disaster recovery capability: Its financial-class multi-site multi-active architecture achieves RPO=0 and RTO<30s and ensures zero data loss. When disasters occur, the service can be switched over quickly and steadily.
3)Online scaling without service interruption: GoldenDB supports Harsh, list, scope, and copy data slicing policies. It supports splitting of popular databases to ensure balanced data distribution, supports associated multi-table expansion to reduce cross-database association query, and supports flexible configuration of expansion plans. The expansion process can be managed visually.
4)Financial-class real-time consistent distributed transactions: GoldenDB integrates the global transaction manager (GTM) to ensure real-time consistent distributed transactions. The processing of distributed transactions keeps transparent to applications, and applications do not need to be reconstructed. The one-phase submission + automatic compensation mechanism improves distributed transaction processing performance.
5)Financial-class reliability: The rapid synchronization technology ensures zero data loss; the group copying technology ensures service continuity, and the returned message counts technology enables flexible configuration of policies.
6)Complete backup and recovery: GoldenDB supports full backup, incremental backup, real-time backup, and scheduled backup policies. Data can be recovered to any time point before data backup and to the globally consistent data state.
7)SQL compatibility: GoldenDB is compatible with standard SQL syntax, MySQL syntax, common Oracle syntax, and supports distributed optimization and distributed batch processing.
ZTE GoldenDB distributed database has been officially put into commercial use in China CITIC Bank, Jiangsu Province Rural Credit Co-operative Union, Bank of Jiangsu, Hunan Provincial Government, and Xiantao Municipal Government. The application scenarios of the GoldenDB distributed database include:
High-concurrency: The product can meet high-concurrency transactions required by government, financial, telecom, and Internet industries and ensure high consistency of data transactions.
Massive data storage access: The product can realize large-capacity and high-scalability database solution.
