Each node in Nacos is responsible for part of the write requests.
Each node will synchronize the new data it is responsible for to other nodes.
Each node regularly sends the check value of its own data to other nodes to maintain data consistency
Each node independently processes read requests and sends responses locally in a timely manner.
The newly added Distro node will pull the full amount of data. (The specific operation is to poll all Distro nodes and pull the full amount of data by sending requests to other machines.)
