坐落在应用服务器与数据库服务器之间的高性能中间件,将写操作路由至主节点、读操作分发至只读节点,应用代码无需改动,大幅提升数据库整体吞吐量。High-performance middleware between app servers and database servers. Routes writes to primary, reads to replicas — no application code changes, dramatically increasing overall throughput.
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.
