A single logical database is spread across a cluster of nodes and thus the need to spread data evenly amongst all participating nodes. Let us understand how MongoDB architecture works. If some of the nodes are responded with an out-of-date value, Cassandra will return the most recent value to the client. This, in turn, means that all nodes in a cluster are treated equally, and a majority of nodes can be used to achieve quorum. Cassandra stores replicas on multiple nodes to ensure reliability and fault tolerance. What is DBMS?
