The master-slave server uses Redis (which is not considered to be saved into MySQL library), how to ensure the data of each machine is unified in real time

All know that Redis has a REDIS-CLI implementation of the subscription publishing function, similar to this, if the master server data is modified, how real-time (in milliseconds) to notify each subordinate server change data? For example, 12306 of the ticket, Beijing, Guangzhou, the server in Shanghai, real-time real-time display of the main server of the remaining votes, once the ticket is completed, how can each server be notified in real-time change status? Small white one, hope enlighten

Since you have made the master-slave configuration, the data modification of the primary server will be automatically synchronized from the server.
