Currently all "live" Cluster data is held in RAM. We will try to add disk capability in a future version.

You can cut per-node memory requirements by adding more nodes. For example, if you have 1.5 GB of data, you can use 4 data nodes configured as 2 node groups of 2 nodes each. In this case, you will have 2 copies of the data (the orginal plus one replica), each copy (that is, each node group) will hold 1.5 GB of data split across 2 nodes, and each individual data node will contain 750 MB of data in RAM. (This doesn't take into account memory required for indexes, but should illustrate the point I'm trying to get across here.)
