A Distributed, Financial-grade Database, Performance up 54%


High Performance

With distributed optimizers and NUMA-aware memory allocation, GaussDB(for openGauss) can handle petabytes of data and deliver excellent TPC-C and TPC-H performance for enterprises.

Elastic Scalability

GTM-lite breaks the performance bottleneck of traditional databases. Compute and storage capacities can be separately and flexibly scaled. You can add up to over 1,000 nodes for a single DB instance.

Commercial Deployment by a Large Bank

A major bank in China used GaussDB(for openGauss) to transform core transaction systems using a distributed architecture.

Large Capacity and High Scalability

GaussDB(for openGauss) supports online scale-out to terabytes or even petabytes of data per instance. There is no need to do sharding, simplifying application development.

Financial-grade High Availability

A single DB instance can be deployed across AZs within the same region to ensure service continuity in case one of the data centers goes down.

High Concurrency

For major business processes, the response latency is less than 3 seconds under high concurrency of transactions. The time needed to return results for reporting and complex query requests is reduced from over 20 minutes to seconds.

Key Technologies Key Technologies

HTAP, High Performance, and Elastic Scalability

GaussDB(for openGauss) helps massively reduce the amount of work involved in migrating and revamping legacy transaction systems using a distributed architecture. 3DC geo-redundant DR keeps your data safe and ensures service continuity.

Industry-Leading Transaction Processing

A NUMA-aware architecture greatly accelerates data processing by reducing cross-core memory access. With strong data consistency for distributed systems and lightweight transaction snapshots, GTM-lite helps improve both single-node and distributed performance by 5x.

Ultra-Low Delay for Complex Queries

GaussDB(for openGauss) uses a massively parallel processing (MPP) architecture to provide the ultimate throughput. Execution plans are dynamically and evenly distributed to all nodes. With symmetric multiprocessing (SMP), multiple CPU cores in a single node perform parallel computing. One instruction operates multiple pieces of data at the same time, greatly reducing the query latency.

Elastic Scalability

You can add up to over 1,000 nodes for a single DB instance to handle high concurrency and complex queries.

Financial-grade High Availability and Security


3DC Geo-Redundant DR

You can deploy a DB instance within a single AZ, across AZs, or across regions as required. In the case of a single failure in an AZ, a recovery point objective (RPO) of zero and a recovery time objective (RTO) of less than 10 seconds can be achieved.

End-to-End Encryption for Data Transmission, Computing, and Storage

In addition to encryption for data transmission and storage, GaussDB(for openGauss) provides industry-leading encryption for data computing as well. Data security is guaranteed for the entire lifecycle.

AI-Native for Intelligent and Efficient Management


Parameter Self-tuning

More than 500 parameters are self-tuned using deep learning and global optimization algorithms. Compared with manual parameter tuning by DBAs, self-tuning helps improve performance by 30% and reduces the time required from days to minutes.

Intelligent Index Recommendations

Intelligent index recommendations analyze and recommend indexes for SQL statements and workloads, reducing the time needed from hours to seconds. Benchmarking tests show an approximately 40x improvement in performance.

Application Scenarios

  • Core Financial Transactions

  • ERP/CRM

  • Government and Enterprise OA
