Subject Replication Factor question
Date Mon, 14 Apr 2014 09:25:23 GMT

currently reading the "Practical Cassandra". In the section about replication factors the
book says:

"It is generally not recommended to set a replication factor of 3 if you have fewer than six
nodes in a data center".

Why is that? What problems would arise if I had a replication factor of 3 and only 5 nodes?

Does that mean that for a replication of 4 I would need at least 8 nodes and for a factor
of 5 at least 10 nodes?

Not saying that I would factor 5 andn 10 nodes, just curious about how this works.

All the best,
