Subject Cassandra Setup Question
Date Wed, 23 Aug 2017 11:53:34 GMT
Hi Community,

Quick question regarding Replication Factor.

In my Production Environment I currently have 6 nodes this will grow to 10 shortly), over
2 datacentres, so currently 3 in each, we want to have Active/Passive setup so the Client
will only speak to DC 1 via load balancing policy, but we want the data to replicate across
both DCs , so that in the event of a DC failure the second DC acts as our DR DC and has  all
the data as well.

The Consistency will be Quorum, but replication Factor does that need to be 3 or 6.
