ES选举-类Bully算法
Bully算法
bully算法是一个分布式系统中动态选择master节点的算法,进程号大的非失效的节点将被选为master。
算法用三种消息类型:
1)选举消息 (Election Message: Sent to announce election.)
2)应答消息(Answer (Alive) Message: Responds to the Election message.)
3)选举成功消息 (Coordinator (Victory) Message: Sent by winner of the election to announce victory.)
