   When Alpha cluster, only one RedisMessageSubscriber should be allowed at the same time. Otherwise, it will repeat consumption. 
   
   You can use the following method to determine whether the current node is the master node, Or you can implement a distributed lock based on Redis inside your component, only one Redis subscriber at a time
   
   ```java
   @Autowride
   NodeStatus nodeStatus;
   
   if(nodeStatus.isMaster()){
     // Is master
   }
   ```
