There must be an objective downtime. When most Sentinel processes in the "Sentinel Group" make SDOWN judgment on the Master master server and communicate with each other through the SENTINEL is-master-down-by-addr command, the Master Server offline judgment is obtained. This method is "objective down", and the English name is: Objectively Down, abbreviated as ODOWN. Through a certain vote algorithm, select one of the remaining slave server nodes to be promoted to Master server node, then automatically modify the relevant configuration and turn on failover.

For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~
