Sentinel (Sentinel) process is used to monitor the working status of Master master server in redis cluster. When Master master server fails, it can switch between Master and Slave servers to ensure high availability of the system. It has been integrated into redis2.6 + version, and Redis Sentinel mode has stabilized after version 2.8. In general, it is also recommended to use later versions of Redis version 2.8 in production environment. Sentinel is a distributed system. You can run multiple sentinel processes in one architecture. These processes use gossip protocols to receive information about whether the Master master server is offline, and use Agreement Protocols to decide whether to perform automatic failover and which Slave to select as the new Master. Each Sentinel process will send messages to other Sentinel, Master and Slave regularly to confirm whether the other party is "alive". If it is found that the other party has not received a response within the specified configuration time (configurable), it will temporarily think that the other party has dropped, which is called "Subjective Down". English name: Subjective Down, SDOWN for short. Subjective Down,

On the other hand, if the brightness is lower than 50% gray, the image will darken, and the mixing method is similar to Multiply. This mode can add shadow to the image. If pure black or pure white is used for mixing, the result will also be pure black or pure white.
