I have changed my replication factor from 3 to 5 and added 2 more nodes I see it’s replicated to all 5 nodes . I kept adding 2 more nodes and still I see replicated to 7 nodes even replication factor is set to 5 , trying to understand where and when is the relevance of replication factor?
Can you expand on what you are looking at which tells you that things are replicated to 7 nodes?
The database is split into ranges and each range should be replicated to 5 nodes. The replicas are spread evenly among all nodes.
