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.
Protection against DDoS attacks
When your business suffers a DDoS attack, this feature can help you resist various attack traffic to ensure normal operation.
Protection against database attacks
Effectively defend against database attacks like SQL injection and brute force attacks.
Data is stored online in a source-replica architecture to ensure security. Moreover, it can be backed up and stored for an extended period of time, allowing for data recovery in the event 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 7–1830 days based on data backup and log backup (binlog). Such backups can be retained for 7–1830 days.
Automatic disaster recovery
Automatic failure detection and failover are supported. Users are not aware of source-replica switchover or failover.
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
You can monitor resources from multiple dimensions and customize alarming thresholds for them. You can also download reports about slow query analysis and SQL running.
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.
