Required Methods§

source

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.
