Objectively Down (ODOWN for short) refers to the judgment of server offline obtained by multiple Sentinel instances after making SDOWN judgment on the same server and communicating with each other through SENTINEL is-master-down-by-addr command. (One Sentinel can ask another Sentinel if the given server is considered offline by sending the SENTINEL is-master-down-by-addr command.)You can scan the following two-dimensional code or directly search the public number: CharlotteDataMining.

The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.
