Cloud Native Database TDSQL-C

A cloud native database with high performance, storage capacity, and compatibility


Cloud Native Database TDSQL-C (TDSQL-C for short) is a new-generation enterprise-grade distributed cloud database developed by Tencent Cloud. It features high performance and availability and combines the strengths of traditional databases, cloud computing, and cutting-edge hardware technologies. It is compatible with MySQL and PostgreSQL and can provide a high throughput of over one million QPS and a massive distributed smart storage capacity of 128 TB, comprehensively ensuring data security and reliability.


High Compatibility

TDSQL-C is compatible with open-source database engines MySQL 5.7 and PostgreSQL 10, allowing queries, applications, and tools of existing databases to be smoothly migrated with almost no code changes required.

Ultra-High Performance

The ultra-high performance of a single node can sustain millions of QPS, which meets the requirements of high-concurrency and high-performance scenarios, ensures the continuity of key businesses, and provides better read/write separation and read/write scalability.

Massive Storage Capacity

TDSQL-C has a massive storage capacity of up to 128 TB in the serverless architecture and features auto scaling, fault checks, and repairs. It is pay-as-you-go, so you only need to pay for what you use. It helps you easily cope with the dynamic changes and continuous growth of your business data volume. In addition, it automatically maintains multiple data replicas to ensure data security and reliability.

Fast Recovery

Compute nodes are stateless and support failover and recovery within seconds. Even if the physical machine where a compute node resides is down, it can be recovered in less than one minute.

High Data Reliability

TDSQL-C clusters support security group and VPC network isolation and automatically maintain multiple replicas of data and backups to ensure data security and provide a data reliability of up to 99.9999999%.

Elastic Scalability

1–15 read-only compute nodes can be quickly added in a cluster within seconds, enabling fast response to business surges and fluctuations.


TDSQL-C has a wealth of powerful features suitable for various enterprise-grade application scenarios.

A VPC allows you to preconfigure an independent network space in the cloud and launch cloud resources in the virtual network you define. You can also create a VPN or Direct Connect connection between your IDC and the VPC to use Tencent Cloud as an extension of your IDC.
