Cassandra Practice Test

Gossip in Cassandra is a protocol used for two primary purposes: to share information between nodes and to ensure that all nodes eventually converge on the same state of the cluster. The correct answer encompasses several truths about how gossip operates within Cassandra's architecture.

Firstly, the constant trickle of network traffic reflects the ongoing nature of the gossip protocol. Nodes in a Cassandra cluster continuously exchange state information with a small amount of data being transmitted at regular intervals. This ensures that all nodes stay informed about the health and status of each other, which is crucial for maintaining the integrity and reliability of the cluster.

Secondly, the assertion that gossip does not lead to network spikes is significant. Unlike bulk data transfers or streaming operations, which can cause sudden surges in network activity, gossip creates only minimal, steady traffic. This means the load on the network remains stable and predictable, avoiding scenarios that could degrade performance or create bottlenecks.

Lastly, when compared to data streaming, the minimal traffic generated by gossip is a crucial consideration. Data streaming in Cassandra involves transferring large volumes of data, such as during writes and reads, which can create significant network load. In contrast, the gossip protocol is designed to use a lightweight approach, which is essential for efficient cluster management without overwhelming the
