nodedb_cluster::mirror::source_handler

Struct SourceHandlerParams 

Source 
pub struct SourceHandlerParams {
    pub local_cluster_id: String,
    pub latest_snapshot_lsn: u64,
    pub snapshot_bytes_total: u64,
}
Expand description

Parameters the source passes to handle_mirror_connection.

Fields§

§local_cluster_id: String

This cluster’s own cluster-id. Compared against the mirror’s declared source_cluster field.

§latest_snapshot_lsn: u64

The highest snapshot LSN the source can offer for this database. If the mirror’s last_applied_lsn equals this value, no snapshot transfer is needed and streaming starts from last_applied_lsn + 1.

§snapshot_bytes_total: u64

Total bytes of the snapshot at latest_snapshot_lsn (0 if streaming will skip the snapshot).
