Govern 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. 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.

Redis configuration requirements

notify-keyspace-events "Kg$shx"

You can use the following command line (redis-cli or any other redis-client) to set notify-keyspace-events

config set notify-keyspace-events "Kg$shx"

or

config set notify-keyspace-events "KA"
