Hello, Let me explain what I am trying to do: I am prototyping 2 Data centers (DC1 and DC2) with two nodes each. Say DC1_n1 and DC1_n2 nodes in DC1 and DC2_n1 and DC2_n2 in DC2. With PropertyFileSnitch and NetworkTopologyStrategy and 'strategy_options of DC1=1 and DC2=1', I am able to ensure that each DC has ONE AND ONLY ONE copy of ALL the keys. But how do I ensure that there is one to one mapping between the nodes? i.e. how to I ensure keys in DC1_n1 = keys in DC2_n1 and keys in DC1_n2 = keys in DC2_n2 ? Right now some keys of DC1_n1 are getting replicated to DC2_n1 and some to DC2_n2 (and the same for DC1_n2 keys).
I am using RPP and calculating tokens to ensure that each node has 25% of the load (using the python script at http://www.datastax.com/docs/0.8/operations/clustering to come up with the tokens) Thanks for any inputs.
