Question-11: You have to restart a node in a Cassandra cluster to apply some patch on it. However, after restart it should take at least 30 minutes to be part of the cluster as well as serving data.
- True
- False
Ans : B
Exp: Cassandra cluster nodes uses the Gossip protocol to discover and share location and state information about the other nodes in Cassandra cluster. However, Gossip information is locally persisted by each node in cluster. So that after restart it can be immediately used. There is no such 30 mins waiting time before start using the cluster.
