• Performance: With DFV storage and vertical optimization of the software and hardware, TaurusDB delivers 7x the performance of MySQL. It can process millions of QPS.

• Scalability: You can add up to 15 read replicas in addition to scaling up or down specifications for a DB instance as needed.

• Storage: TaurusDB automatically grows storage as needed, to up to 128 TB per DB instance.

• Reliability: To ensure data security, DB instances can be deployed across AZs, and a DB instance failover can be completed in seconds.

What Is TaurusDB Enterprise Edition?

TaurusDB Enterprise Edition is an enterprise-grade cloud-native database fully compatible with MySQL. It decouples compute from storage and uses Huawei-developed Data Function Virtualization (DFV), which scales to up to 128 TB per instance. A failover can be complete within seconds. It provides the superior performance and high availability of a commercial database at the price of an open-source database.

Advantages

• Performance

  • By decoupling compute from storage and using a "log as database" architecture, TaurusDB delivers seven times the performance of open-source databases.

  • Remote Direct Memory Access (RDMA) is used for data transfer in database systems to break through the I/O performance bottleneck.

  • TaurusDB supports kernel features, such as query result cache, query plan cache, and online DDL, to improve user experience.

• Scalability

  • Horizontal scaling: In addition to a primary node, you can add up to 15 read replicas for an instance to handle high-concurrency requests.

  • Vertical scaling: You can upgrade or downgrade instance specifications within minutes.

• Availability

  • You can deploy an instance across AZs or regions to improve DR capabilities.

  • Three copies of the data are stored to ensure reliability.

  • TaurusDB uses shared distributed storage. If the primary node fails, one of the read replicas is promoted to primary with an RPO of zero.

  • The latency between the primary node and its read replicas is several milliseconds, ensuring high availability.

• Security

  • With shared distributed storage, TaurusDB can achieve service recovery within seconds and near-zero data loss.

  • VPCs, security groups, SSL connections, and data encryption are used to strictly control access security.

  • TaurusDB has passed over 15 security certifications, including ISO 27001, CSA, Trusted Cloud, and China's level-3 certification for information security protection. It is the first in China to obtain the highest NIST CSF certification.

• Compatibility

  TaurusDB is fully compatible with MySQL. You can easily migrate your MySQL databases to TaurusDB without refactoring existing applications.

• Backup

  • Snapshots are created in seconds and can be used to restore data quickly.

  • The storage system enables data to be restored to any point in time without replaying incremental logs.

• Storage

  • Based on Huawei-developed DFV distributed storage, TaurusDB supports up to 128 TB of storage.

  • TaurusDB automatically grows storage as needed.

• Operator pushdown

  Column projection, condition filtering, and aggregation calculation are pushed from compute nodes down to storage nodes for parallel processing. This improves query performance and reduces network traffic and the load on the compute nodes. Operator pushdown is integrated with parallel query to execute the entire process in parallel.
