CoSky High-performance, low-cost microservice governance platform (Service Discovery and Configuration Service)

中文文档

CoSky 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, CoSky provides ultra-high TPS&QPS (100,000+/s JMH Benchmark). CoSky combines the process cache strategy + Redis PubSub to achieve real-time process cache refresh, with unparalleled QPS performance (70,000,000+/s JMH Benchmark) and real-time consistency between process cache and Redis.

CoSky-Mirror (Real-time synchronization of service instance change status)

CoSky-Mirror is like a mirror placed between Nacos and CoSky to build a unified service discovery platform.

Role-based access control(RBAC)

  • cosky: Reserved username, super user, with the highest authority. When the application is launched for the first time, the super user (cosky) password will be initialized and printed on the console. Don't worry if you forget your password, you can configure enforce-init-super-user: true, CoSky will help you reinitialize the password and print it on the console.
---------------- ****** CoSky -  init super user:[cosky] password:[6TrmOux4Oj] ****** ----------------
  • admin: Reserved roles, super administrator roles, have all permissions, a user can be bound to multiple roles, and a role can be bound to multiple resource operation permissions.
  • Permission control granularity is namespace, read and write operations
