Overview

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

Benefits
High Compatibility

Work well with open-source MySQL 5.7 and PostgreSQL 10 engines. It supports queries of existing databases as well as migration of their applications and tools with minimal code change.

Ultra-High Performance

Sustain millions of QPS on a single node for scenarios requiring high concurrency and performance, ensuring the continuity of critical workloads. It also provides read/write separation and scalability.

Massive Storage Capacity

Offer a massive storage capacity of up to 128 TB in the serverless architecture and features auto scaling, fault checks, and auto-repairs, helping you cope with the dynamic changes and continuous growth of your business data volume.

Fast Recovery

Support for instant failover and recovery on stateless compute nodes. Even a failed physical machine can be recovered in less than one minute on a compute node.

High Data Reliability

Support security group and VPC network isolation. It also automatically maintains multiple replicas of data and backups to ensure data security and an availability up to nine nines.

Elastic Scalability

Add 1-15 read-only compute nodes to a cluster in seconds based on workloads, enabling fast response to business surges and fluctuations.

Features
VPC

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

Security Group

A security group is a stateful virtual firewall with filtering capabilities. It is used in Tencent Cloud as an important means of network security isolation, and it can be used to set network access controls for one or more CVM instances.

Multiple Layers of Security Protection

TDSQL-C provides multiple layers of security protection by default, helping defend against various attack traffic for business continuity in case of DDoS attacks. It can effectively block database attacks such as SQL injections and brute force attacks, reducing business interruptions and losses.

Comprehensive Daily Monitoring

TDSQL-C offers many common database performance metrics that can be monitored at the minute level in real time. It supports custom alarms for these metrics and sends notifications to Ops personnel upon alarm triggering, allowing them to quickly respond to the problems. It also provides reports on slow query analysis and SQL running for download, enabling you to identify factors affecting database performance.

Finer Granularity Monitoring

TDSQL-C provides 15 core database performance metrics that can be monitored at the second level in real time, helping you keep track of the health of your instances and quickly locate performance issues.

Database Logs

Slow query logs and error logs can be downloaded to help you understand the factors affecting your database performance.
