Subject Cassandra 1.0.6 multi data center question
Date Thu, 09 Feb 2012 03:04:37 GMT
Hi All

I have 2 Cassandra data center (DC1=>1 node, DC2=>2 nodes).

XXX.XXX.XXX.XXX DC2         RAC1        Up     Normal  44.3 KB        
33.33%  0

33.33%  113427455640312814857969558651062452224   

My requirement is want to create a keyspace and want to replicate within
only DC1. So that keyspace is not visible to the DC2. I have create a
keyspave like this:
CREATE KEYSPACE WCSDC WITH placement_strategy = 'NetworkTopologyStrategy'
AND strategy_options={DC1:1};

But when I create the above keyspace from DC1 using cassandra-cli, the
schema is updated all over the cluster and keyspave is created on DC2 as

Could someone please help me to solve this issue. Thanks.
