The repeat rate of the dataCenterId, the value of the maximum dataCenterId times the time of each Raft election. The time for raft to select the master is generally measured in seconds. If the interval of an election is 5 seconds, it will take 150 seconds for the DataCenterId to be repeated. This is still based on the situation that the new master needs to be selected after each election of the Leader
