Redis cluster election

1. Redis Cluster Features

   All Redis nodes are interconnected with each other, using binary protocols to optimize bandwidth and transfer speeds internally

   The fail of a node is only effective if it is not monitored by more than half of the nodes in the cluster

   Client and Redis node direct connection does not need proxy, link any node in the cluster can

   Redis-cluster. All nodes are mapped to "0-16383" (hash slots), and cluster is responsible for maintaining node

2. Cluster fault tolerance and election

   (1) Node fault tolerant election when all master is elected, if more than half of the master communication node hangs, the master cluster is considered to be hung off

   (2) If the master of any cluster is hung and the master is not slave, the cluster enters the fail state

   (3) More than half of the master in the cluster is not available
