Cluster transport tuning for QUIC connections and Raft consensus.

Fields

raft_tick_interval_ms: u64

election_timeout_min_secs: u64

election_timeout_max_secs: u64

election_timeout_min_ms: u64

Sub-second override for election_timeout_min_secs. When non-zero, this value (in milliseconds) is used instead of the seconds field. Production deployments leave this 0 and use the seconds field; integration tests set this to ~150ms so 3-node convergence completes in under a second instead of 1–2 seconds per cluster spawn.

election_timeout_max_ms: u64

Sub-second override for election_timeout_max_secs. See Self::election_timeout_min_ms.

rpc_timeout_secs: u64

quic_keep_alive_secs: u64

quic_idle_timeout_secs: u64

quic_max_bi_streams: u32

quic_max_uni_streams: u32

quic_receive_window: u32

quic_send_window: u32

quic_stream_receive_window: u32

broadcast_threshold_bytes: usize

Maximum payload size for broadcast join strategy selection. Above this threshold, shuffle join is preferred over broadcast. See nodedb_cluster::distributed_join::select_strategy.

ghost_sweep_interval_secs: u64

How often (in seconds) to sweep for dangling ghost nodes. See nodedb_cluster::ghost_sweeper::DEFAULT_SWEEP_INTERVAL.

health_ping_interval_secs: u64

Cluster health check ping interval in seconds. See nodedb_cluster::health::DEFAULT_PING_INTERVAL.

health_failure_threshold: u32

Consecutive ping failures before marking a node as down. See nodedb_cluster::health::DEFAULT_FAILURE_THRESHOLD.

descriptor_lease_duration_secs: u64

Default duration of a descriptor lease, in seconds. Used by SharedState::acquire_descriptor_lease when the caller does not specify an explicit duration. The renewal loop re-acquires leases at 80% of this value.

descriptor_lease_renewal_check_interval_secs: u64

How often the descriptor-lease renewal loop wakes up to look for near-expiry leases. Default: 60s. Tests override this with a much smaller value (e.g. 1s) to drive renewal within a multi-second test budget.

descriptor_lease_renewal_threshold_pct: u8

Re-acquire leases when the remaining time (until expiry) falls below this percentage of the original duration. Default: 20 (re-acquire when 80% of the duration has elapsed). Tests can set this to 50 to make renewal trigger earlier in the lease lifecycle.

Implementations

impl ClusterTransportTuning

pub fn effective_election_timeout_min_ms(&self) -> u64

Effective minimum election timeout. Returns _ms when non-zero, otherwise _secs * 1000. Tests use _ms for sub-second values; production leaves it 0 and the seconds field wins.

pub fn effective_election_timeout_max_ms(&self) -> u64

Effective maximum election timeout. See Self::effective_election_timeout_min_ms.

Trait Implementations

impl Clone for ClusterTransportTuning

fn clone(&self) -> ClusterTransportTuning

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClusterTransportTuning

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ClusterTransportTuning

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ClusterTransportTuning

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ClusterTransportTuning

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
