I'm new to Cassandra. Let's assume I have 3 nodes and Replication Factor(RF) of the keyspace is 3. Can I safely assume that if 2/3 nodes are down, I still get the complete data for a query irrespective of the Consistency level? Keeping 2/3 nodes as down, which consistency level will assure me the complete data for a query?

Cassandra Consistency Level and Replication Factor

Can I safely assume that if 2/3 nodes are down, I still get the complete data for a query irrespective of the Consistency level?
