类 JRaftServer

java.lang.Object

com.alibaba.nacos.core.distributed.raft.JRaftServer

public class JRaftServer
extends java.lang.Object

JRaft server instance, away from Spring IOC management.

Why do we need to create a raft group based on the value of LogProcessor group (), that is, each function module has its own state machine. Because each LogProcessor corresponds to a different functional module, such as Nacos's naming module and config module, these two modules are independent of each other and do not affect each other. If we have only one state machine, it is equal to the log of all functional modules The processing is loaded together. Any module that has an exception during the log processing and a long block operation will affect the normal operation of other functional modules.
