Struct CrossDcCoordinator 

Source 
pub struct CrossDcCoordinator { /* private fields */ }
Expand description

Cross-DC replication coordinator

Coordinates replication between a primary and its replicas. In production, this would use network transports; here it simulates in-process delivery for testing.

Implementations§

Source§

impl CrossDcCoordinator

Source

pub fn new(primary: Arc<PrimaryDcManager>) -> Self

Create a coordinator with a primary and replicas

Source

pub fn add_replica_node(&mut self, dc_id: DcId, replica: Arc<ReplicaDcManager>)

Add a replica to the coordinator

Source

pub fn replicate_once(&self) -> Result<HashMap<DcId, usize>>

Perform one round of replication: ship entries from primary to all replicas

Source

pub fn replication_health(&self) -> ReplicationHealth

Get overall replication health
