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-native 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-native 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.
