Required Methods

fn select_nodes(
    &mut self,
    local_node: SocketAddr,
    local_dc: &str,
    total_nodes: usize,
    data_centers: &mut BTreeMap<Cow<'static, str>, NodeCycler>,
    consistency: Consistency
) -> Result<Vec<SocketAddr>, ConsistencyError>

Produces a set of node addresses based on the desired consistency level.

A set of nodes are provided with a mapping of data_center -> node_addresses.
