What TencentDB for MySQL Database Proxy is

TencentDB for MySQL Database Proxy sits between an application and TencentDB for MySQL, relaying database requests through a separate proxy address. One application connection can route reads to read-only instances and writes to the source instance. Connection pooling can reduce load from frequent or excessive connections, and transaction splitting can send reads and writes within a transaction to different instances. A multi-node cluster across availability zones supports failover and availability; proxy resources are isolated per instance. Tencent says each proxy can process up to 100,000 requests per second, and nodes can be scaled from 1 to 60. Request counts, CPU and memory are monitored at second-level granularity. Configuration changes and source or read-only instance changes can be hot-loaded without network disconnections or restarts. The service supports MySQL 5.7 and 8.0 and the TencentDB for MySQL read-only analysis engine. The pay-as-you-go plan is $0.07 a month; its stated Shanghai-region rate is billed at $0.06865672 per CU per hour, with different prices in other regions. A 15-day trial is offered for up to three instances per Tencent Cloud UIN account.

Good

Availability
The proxy uses a multi-node cluster and cross-availability-zone deployment to support failover and availability.checked 8 Oct 2026
Connection pooling
Connection pooling can reduce load caused by frequent new connections and excessive connections.checked 8 Oct 2026
Hot reload
Proxy configuration can be hot-loaded after source switching, configuration changes, or read-only instance additions and removals without network disconnections or restarts.checked 8 Oct 2026
Isolation and performance
Proxy resources are isolated per instance, and each proxy can process up to 100,000 requests per second.checked 8 Oct 2026
