Setting Up Node Topology

Define node topologies for every node in the cluster.

Define your cluster's topology by specifying a topology for each node in the cluster. You can use topology to group nodes by rack or switch, depending on how the physical cluster is arranged and how you want data-fabric to place replicated data.

Topology paths can be as simple or complex as needed to correspond to your cluster layout. In a simple cluster, each topology path might consist of the rack only (for example, /rack-1). In a deployment consisting of multiple large datacenters, each topology path can be much longer (for example, /europe/uk/london/datacenter2/room4/row22/rack5/). Data Fabric uses topology paths to spread out replicated copies of data, placing each copy on a separate path. By setting each path to correspond to a physical rack, you can ensure that replicated data is distributed across racks to improve fault tolerance.
