What it is

TencentDB for MySQL Database Proxy is a managed service positioned between an application and TencentDB for MySQL. Applications connect through a proxy address while the service routes reads to read-only instances and writes to the source instance. Connection pooling reduces the burden of frequent or excessive new connections, and transaction splitting can separate reads and writes within transactions. A multi-node cluster across availability zones supports failover. Proxy resources are isolated per instance, with stated capacity of up to 100,000 requests per second per proxy. Nodes can scale from 1 to 60, while request, CPU, and memory metrics are monitored at second-level granularity. Configuration can be hot-loaded after source switches, changes, or read-only instance changes without disconnecting or restarting. Access modes either balance connections across nodes or select a nearby node. Supported databases are MySQL 5.7, MySQL 8.0, and the TencentDB read-only analysis engine. The pay-as-you-go plan is listed at $0.07 a month, with regional CU pricing details.

Spec sheet

Purpose
The proxy sits between TencentDB for MySQL and an application and relays database requests through a separate proxy address.Read 8 Oct 2026 · intl.cloud.tencent.com
Access modes
Balanced distribution spreads connections across proxy nodes, while nearby access selects a node in the same availability zone or with the shortest path.Read 8 Oct 2026 · intl.cloud.tencent.com
Availability
The proxy uses a multi-node cluster and cross-availability-zone deployment to support failover and availability.Read 8 Oct 2026 · intl.cloud.tencent.com
Connection pooling
Connection pooling can reduce load caused by frequent new connections and excessive connections.Read 8 Oct 2026 · intl.cloud.tencent.com
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.Read 8 Oct 2026 · intl.cloud.tencent.com
Isolation and performance
Proxy resources are isolated per instance, and each proxy can process up to 100,000 requests per second.Read 8 Oct 2026 · intl.cloud.tencent.com
Network forwarding limits
With network forwarding enabled, adaptive load balancing, connection pooling, and transaction splitting are unsupported.Read 8 Oct 2026 · intl.cloud.tencent.com
Read/write routing
It can route read requests to read-only instances and write requests to the source instance through one application connection address.Read 8 Oct 2026 · intl.cloud.tencent.com
Scaling and monitoring
Proxy nodes can be dynamically scaled from 1 to 60, and performance metrics such as request counts, CPU, and memory are monitored at second-level granularity.Read 8 Oct 2026 · intl.cloud.tencent.com
Transaction splitting
Transaction splitting can send reads and writes within a transaction to different instances to reduce source-instance load.Read 8 Oct 2026 · intl.cloud.tencent.com
Trial offer
The billing announcement describes a 15-day proxy free-trial promotion for up to three instances per Tencent Cloud UIN account, with a specified discounted node capacity.Read 8 Oct 2026 · intl.cloud.tencent.com
Version requirement
Connection pooling requires MySQL 5.7 kernel minor version 20211030 or later, or MySQL 8.0 kernel minor version 20230630 or later.Read 8 Oct 2026 · intl.cloud.tencent.com
