Subject Question about replica and replication factor
Date Tue, 20 Sep 2016 04:08:59 GMT
Hi there,
    I have a question about the replica and replication factor. 
    For example, I have a cluster of 6 nodes in the same data center. Replication factor RF
is set to 3  and the consistency level is default 1. According to this calculator http://www.ecyrd.com/cassandracalculator/,
every node will store 50% of the data.
    When I want to read all data from the cluster, how many nodes should I read from, 2 or
1? Is it 2, because each node has half data? But in the calculator it show 1: You are really
reading from 1 node every time.
   Any suggestions? Thanks!
