redis 集群之间是使用什么网络协议连接的？

Question

谷歌说是 gossip 协议

但是 chatGPT 说是 Redis Cluster Bus 协议

Answer 1

Redis Cluster Bus是统称，节点之间通过TCP进行连接，节点之间的通信是通过gossip协议

下面摘自官方文档

To perform their tasks all the cluster nodes are connected using a TCP bus and a binary protocol, called the Redis Cluster Bus. Every node is connected to every other node in the cluster using the cluster bus. Nodes use a gossip protocol to propagate information about the cluster in order to discover new nodes, to send ping packets to make sure all the other nodes are working properly, and to send cluster messages needed to signal specific conditions

Answer 2

RESP协议
