SyncDaemon

database_replicator::xmin::daemon

Struct SyncDaemon 

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

SyncDaemon orchestrates continuous xmin-based replication.

It runs periodic sync cycles that:

  1. Read changed rows from source using xmin
  2. Apply changes to target using upsert
  3. Periodically run reconciliation to detect deletes
  4. Persist sync state for resume capability

Implementations§

Source§

impl SyncDaemon

Source

pub fn new(source_url: String, target_url: String, config: DaemonConfig) -> Self

Create a new SyncDaemon with the given configuration.

Source

pub async fn run_sync_cycle(&self) -> Result<SyncStats>

Run a single sync cycle for all configured tables.

This is the main entry point for synchronization. It:

  1. Loads or creates sync state
  2. Connects to source and target databases
  3. Syncs each table
  4. Saves updated state
Source

pub async fn run_reconciliation(&self) -> Result<SyncStats>

Run reconciliation to detect and delete orphaned rows.

Source

pub async fn run(&self, shutdown: Receiver<()>) -> Result<()>

Run the daemon continuously until stopped.

This starts the main loop that runs sync cycles at the configured interval. Reconciliation runs at its own interval if configured.
