QuorumConfig

Struct QuorumConfig 

Source
pub struct QuorumConfig {
    pub mode: QuorumMode,
    pub timeout: Option<Duration>,
}
Expand description

Quorum configuration stored alongside ReplicationConfig.

Fields§

§mode: QuorumMode§timeout: Option<Duration>

How long the coordinator waits for acks before giving up. None = wait forever (use for strong consistency only when you can tolerate the writer stalling on a partitioned region).

Implementations§

Source§

impl QuorumConfig

Source

pub fn async_commit() -> QuorumConfig

Ack immediately. Loss tolerance = 0 under primary failure.

Source

pub fn sync(min_replicas: usize) -> QuorumConfig

Wait for n replicas to ack (any region). Typical PG-like “synchronous_commit = on, synchronous_standby_names = ‘ANY n’”.

Source

pub fn regions<I, S>(regions: I) -> QuorumConfig
where I: IntoIterator<Item = S>, S: Into<String>,

Wait for at least one replica from each region in the set. Use this for disaster-recovery deployments across cloud regions.

Source

pub fn with_timeout(self, timeout: Duration) -> QuorumConfig

Source

pub fn without_timeout(self) -> QuorumConfig

Source

pub fn is_async(&self) -> bool

Is this config ack-first (no wait)?
