You can do something like this: Divide your nodes up into 4 datacenters art1,art2,art3,core
[default@unknown] create keyspace art1 placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy' and strategy_options=[{art1:2,core:2}]; [default@unknown] create keyspace art2 placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy' and strategy_options=[{art2:2,core:2}]; [default@unknown] create keyspace art3 placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy' and strategy_options=[{art3:2,core:2}]; [default@unknown] create keyspace core placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy' and strategy_options=[{core:2}]; On Tue, Nov 27, 2012 at 5:02 PM, Artist <jer...@simpleartmarketing.com>wrote: > > I have 3 art-servers each has a cassandra cluster. > Each of the art-servers has config/state information stored in a Keyspaces > respectively called > art-server-1-current-state, art-server-2-current-state, > art-server-3-current-state > > in my core server I have a separate Cassandra cluster.
