Answer / Shubham Gangwar
In Apache Cassandra, a snitch is a component that determines which nodes a replica should reside on based on a defined data center or rack configuration. It helps to optimize network topology for better performance and availability by minimizing the network latency between data and its replicas. For example, a SimpleSnitch categorizes each node in the cluster into a single datacenter, while a GossipingPropertyReferencedSnitch categorizes nodes based on IP addresses and their network properties. Another example is RackInferringSnitch, which infers rack information from the node labels.
