Struct ClusterConfig

}

Per-cluster knobs the shell binds to a listener’s flows. Mirrors the UdpClusterConfig proto but stays in pure-core terms. Defaults match the proto defaults.

Fields

cluster: ClusterId

Cluster the listener routes to.

affinity_with_port: bool

Hash src_ip + src_port (true) vs src_ip only (false) into the backend-selection affinity key. Maps the UdpAffinityKey proto enum. Flows are always keyed on the full source address (FlowKey).

responses: u32

Expected replies per flow before close. 0 = unlimited (DNS = 1).

requests: u32

Max client datagrams per flow before close. 0 = unlimited.

front_timeout: Duration

Idle timeout (client direction). Resets on every datagram.

back_timeout: Duration

Idle timeout (upstream direction). Resets on every reply.

send_proxy_protocol: bool

Prepend a PPv2 DGRAM header to upstream datagrams.

proxy_protocol_every_datagram: bool

PPv2 on every datagram (true) vs first-datagram-only (false, default).

max_flows_per_ip: u64

Concurrent flows one source IP may hold on this cluster, per listener. 0 = unlimited. Resolved by the shell from the cluster’s own max_connections_per_ip; the global default is not inherited, so an absent value is unlimited.

max_flows_per_subnet: u64

Concurrent flows one source subnet may hold on this cluster, per listener. 0 = unlimited. Resolved from max_connections_per_subnet the same way; the subnet is the source IP masked to the two prefixes below.

subnet_ipv4_prefix: u32

IPv4 prefix length, in bits, of a subnet for max_flows_per_subnet.

subnet_ipv6_prefix: u32

IPv6 prefix length, in bits, of a subnet for max_flows_per_subnet.
