JarCastingGovern Service On Redis (Service Discovery and Configuration Service)
Govern Service is a lightweight, low-cost service registration, service discovery, and configuration service SDK. By using Redis in the existing infrastructure (I believe you have already deployed Redis), it doesn’t need to bring extra to the operation and maintenance deployment. Cost and burden. With the high performance of Redis, Govern Service provides ultra-high TPS&QPS (10W+/s JMH Benchmark). Govern Service combines the process cache strategy + Redis PubSub to achieve real-time process cache refresh, with unparalleled QPS performance and real-time consistency between process cache and Redis.
