Consistency vs Replication Factor

Points to be considered in the multi node cassandra setup :

1) For strong data consistency, Should have
(WriteConsistency + ReadConsistency) > ReplicationFactor

2) For Handling Node failures, Should have
(write consistency < Replication Factor) AND (read consistency > 1 AND read consistency < Replication Factor)
Example : Quorum is the best setup for handling node failures
(i.e) Quorum = (RF / 2) + 1

3) Having Same Replication Factor with Write / Read consistency will have Zero Node Failures

DataConsistency :

Cluster Size	Replication Factor	Write and Read Consistency	Number of node failures it can handle	Number of nodes to read for consistency & Async Read	Number of nodes to write for consistency & non-consistent Write	Recommended
5 nodes
5	3	WC = 2, RC = 2 (Quorum)	1	Read = 2, Async Read = 1	Write = 2, non-cons Write = 1	Yes
5	3	WC = 3, RC = 1	0	Read = 1, Async Read = 2	Write = 3, non-cons Write = 0	No (Zero Node Failures)
5	4	WC = 2, RC = 2 (Quorum)	2	Read = 2, Async Read = 2	Write = 2, non-cons Write = 2	No (Eventually Consistent)
5	4	WC = 3, RC = 2	1	Read = 2, Async Read = 2	Write = 3, non-cons Write = 1	Yes
3 nodes
3	3	WC = 2, RC = 2 (Quorum)	1	Read = 2, Async Read = 1	Write = 2, non-cons Write = 1	Yes
3	3	WC = 3, RC = 1	0	Read = 1, Async Read = 2	Write = 3, non-cons Write = 0	No (Zero Node Failures)
3	2	WC = 2, RC = 1	0	Read = 1, Async Read = 1	Write = 2, non-cons Write = 0	No (Zero Node Failures)
