Gossiper is a peer-to-peer communication protocol that a node uses to communicate with the other nodes in the cluster. When the nodes gossip with each other, they share information about themselves and retrieve information on a subset of other nodes in the cluster. Eventually, this allows a node to store and understand state information about every other node in the cluster.
Each node's gossiper runs once per second (Saha 2017) and initiates communication with up to three other nodes. The gossip protocol first runs when the node is attempting to join the cluster. As a new node contains no information on the current network topology, it must be preconfigured with a list of current live nodes or seeds to help it start the communication ...
