读写智能路由Intelligent Read-Write Routing
自动解析 SQL 语义，将 SELECT 语句分发至只读节点，DML/DDL 路由至主节点，无需修改应用代码。
Automatically parses SQL semantics — SELECT routed to read replicas, DML/DDL to primary. No application code changes required.
多节点负载均衡Multi-Node Load Balancing
按权重将读请求均衡分发至多个只读节点，支持轮询、权重、最少连接等多种策略，横向扩展能力强。
Distributes read requests across multiple replicas by weight. Supports round-robin, weighted, and least-connection strategies for elastic horizontal scaling.
查询结果缓存Query Result Caching
将热点 SELECT 查询结果缓存于内存，显著降低数据库读压力，提升高并发场景下的响应速度。
Caches hot SELECT query results in memory, significantly reducing database read pressure and improving response times in high-concurrency scenarios.
Watchdog 高可用 · 秒级故障转移Watchdog HA · Seconds-Level Failover
内置 Watchdog 监控机制，检测节点故障后秒级自动摘除，不影响业务连续性，支持故障节点自动重新加入。
Built-in Watchdog monitoring removes failed nodes within seconds without disrupting business continuity. Failed nodes auto-rejoin after recovery.
SSL/SM3/MD5 加密连接SSL / SM3 / MD5 Encrypted Connections
支持 SSL/TLS、国密 SM3、MD5 等多种认证加密方式，无明文密码传输，满足安全合规要求。
Supports SSL/TLS, Chinese national SM3, and MD5 authentication. No plaintext passwords — meets security compliance requirements.
