Abstract

The invention discloses a data consistency method for a distributed service discovery cluster in a micro-service architecture. The method comprises the following steps: when a service instance of a client is started, any one service discovery node is selected from the service discovery node cluster as a Leader node for connection; sending the own service information to the Leader node; other service discovery nodes in the service discovery node cluster are used as Flower nodes; wherein the service information comprises a service name, an IP address, a port number, a service instance current state, a service instance data type, a Leader node ID, a data version number, time for writing data into a certain service discovery node, time for writing the data into a service discovery node clusterand a state whether the data is submitted or not; the Leader node stores the service information in a tree structure; and the Leader node copies the service information to other Folower nodes.

Description

technical field [0001] The present invention relates to the field of distributed service discovery cluster technology in microservice architecture, in particular to a data consistency method for distributed service discovery cluster in microservice architecture, which simplifies the algorithm while ensuring the data consistency of cluster nodes by improving the Raft algorithm process. Background technique [0002] Since its introduction, the microservice architecture has been favored by system designers because of its good flexibility and scalability, and has gradually become a mainstream solution in the design of enterprise-level information system architecture. Service discovery is one of the core components of the microservice architecture, and its high availability has become an important factor affecting the overall stability of the entire microservice architecture. Single-point deployment of service discovery will not only bring about performance bottlenecks, but may ...
