Replacement vs. addition is a situational trade-off, but ultimately the problem remains that you need to bring more RAM to the party. My biggest RAM consumer stores historical data for a goods trading platform. Each trade is a unique key, with all the trade data being the value. Access speed is important, but not as critical as the other goodies I get from Riak (replication and automated rebalancing). Metadata is stored separately, but I hope to change that with Riak 1.0 secondary indexes.
