Master-slave concept

A master can have multiple slave, and a slave can have multiple slave. Thus, a strong multi-level server cluster architecture is formed.

Master is used to write data, and slave is used to read data. According to statistics, the read-write ratio of the website is 10:1.

Read-write separation can be achieved through master-slave configuration.

Both master and slave are an instance of redis (redis service)
