The strengths described in this document are exclusive to dual-node and three-node TencentDB for MySQL instances.
Read/write separation is supported
Read-only replicas can be mounted to TencentDB for MySQL. One-source-multiple-replica architecture allows you to respond to massive requests. RO group with load balancing feature is supported to greatly optimize the pressure distribution among read-only replicas.
Powerful hardware ensures high performance
NVMe SSD features high IO performance, ensuring smooth reads and writes.
A maximum of 240,000 QPS and a maximum storage space of 6 TB are supported for an instance.
When you suffer a DDoS attack, this feature can help you resist various attack traffic, ensuring the normal operation of businesses.
Protection against database attacks
Effectively defense against such database attacks as SQL injection and brute force attacks.
Data is stored online in a source/replica architecture, ensuring high data security. Moreover, backup data can be stored for an extended time period, allowing for data recovery in case of a database disaster.
Transparent data encryption (TDE) feature guarantees the security of real-time data and backup data.
Financial-grade data audit feature helps prevent core data theft, trace non-compliant operations, and locate malicious pulls.
Real-time hot backup
The dual-server hot backup mechanism supports lossless restoration of data from the last 7–732 days based on data backup and log backup (binlog). Such backups can be retained for 7–732 days.
Automatic disaster recovery
Automatic failure detection and automatic failover are supported. Procedures of source/replica switchover and failover are imperceptible to users.
Easy management of massive databases
Databases can be managed via command line or console. Batch database management, permission setting, and SQL import are supported.
Data import and backup rollback
Multiple data import methods are provided for initialization. Data is backed up automatically on a daily basis. TencentDB allows data to be rolled back to any point in time within the retention period based on backup files.
Professional monitoring and alarm
Multidimensional monitoring and alarming based on custom resource thresholds are supported. You can also download slow query analysis reports and complete SQL running reports.
A variety of access methods
Access to the public network and VPC is supported. You can connect TencentDB instances to your IDC, a private cloud, or other computing resources for deployment in a hybrid cloud conveniently.
