Powerful and Flexible

Powerful and Flexible

  • 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.

  • High Scalability

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

Commercial Deployment by a Large Bank

Commercial Deployment by a Large Bank

A major bank in China used GaussDB(for openGauss) to create distributed core transaction system.

  • Large Capacity and High Scalability

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

  • Financial-grade High Availability

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

  • High Concurrency and Performance

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

Key Technologies


HTAP, High Performance, and Elastic Scalability

HTAP, High Performance, and Elastic Scalability

GaussDB(for openGauss) helps reduce the massive workloads involved with 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 the distributed architecture, strong data consistency, and lightweight transaction snapshots, GaussDB(for openGauss) improves both single-node and distributed performance by 5x in the GTM-lite mode.

  • 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 is applied to multiple pieces of data at the same time, greatly reducing the query latency.

  • Elastic Scalability

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

Financial-grade High Availability and Security

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, Efficient Management

AI-Native for Intelligent, 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 improves 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.
