Core Features
Financial-Grade High Availability
- Supports Shared Storage Cluster (SSC) to meet core business requirements in local data centers, with RPO=0 and RTO<5 seconds.
- Supports Primary-Standby High Availability (HAC) for active-active dual-site deployment in the same city, ensuring data consistency across active-active clusters, with RPO=0 and RTO<10 seconds.
- Supports Remote Disaster Recovery (RHAC) for cross-region disaster tolerance, with RPO<100 seconds and RTO<2 minutes.
- Supports two-site three-center high availability deployment, with remote disaster recovery distance of more than 1,000 kilometers.
- All high availability capabilities are built into the database service itself, with no third-party components required.
- High availability level reaches 99.999% (annual downtime less than 5 minutes).
Extensive SQL Syntax Compatibility
- Provides three syntax-compatible modes: GBase, Oracle, and MySQL.
- Oracle mode syntax compatibility reaches 95%, supporting all commonly used Oracle database objects.
- Fully supports PL/SQL and partial Oracle advanced features such as dblink, flashback, etc.
- MySQL mode syntax compatibility reaches 90%, supporting most MySQL data types and built-in functions.
Complete Supporting Tools
- MTK: Heterogeneous database migration tool
- RTSync: Data synchronization tool
- GDS: Client tool
- GEM: Monitoring and operation & maintenance management platform
- SQLExplorer: SQL capture tool
Stable and Efficient Performance
- Supports ten-thousand-level concurrent connections for data volumes within 100 terabytes.
- Shared storage high availability cluster supports up to 16 nodes, with nearly linear performance improvement and scalability ratio above 0.9.
- Single-node capacity can reach hundreds of terabytes.
- In mainstream hardware environments, the measured TPS in financial core business scenarios can reach over 10,000.

Commercial Value
- It features a built-in financial-grade high-availability solution, enabling users to obtain stable and continuous database service capabilities at no extra cost.
- The single-node capacity can reach hundreds of terabytes, supporting larger storage with less hardware investment while reducing operation and maintenance costs.
- Based on a dynamically scalable architecture, it can fully utilize the computing resources of servers to provide users with cost-effective processing power.
- Possessing a "full license" in the security field, it is committed to delivering highly secure and efficient transactional data management capabilities for China's IT information systems in the security domain, and contributing to national information security.
Technical Advantages
- Achieves snapshot isolation through an in-memory MVCC mechanism, meaning reads do not block writes and writes do not block reads.
- Provides an ultra-fast primary-standby switchover mode, achieving RPO=0 and RTO<5 seconds under load pressure testing.
- Fully supports online DDL operations, reducing the blocking impact of DDL operations on production business.
- Supports a column‑storage engine, which significantly improves complex query performance and meets business requirements in HTAP scenarios.
- Primary-standby switchover supports connection persistence, session persistence and transaction persistence, providing ultimate guarantee for business continuity.
- Supports high-performance indexes for highly concurrent writes, enabling high-speed aggregate queries under high-load TP workloads.
- Deeply adapted to China's CPU architectures, enhancing high performance in multi-NUMA environments.
- Built-in data replication engine supports full and incremental data synchronization, as well as breakpoint resume and data comparison.
